Description

Field of the Invention

[0001] The present invention generally relates to an ecologic packaging with separable composite materials, and more specifically to a vacuum skin package having a fiber-based packaging base from which a skin package composite is peelable and removable without fiber-tear.

Background of the Invention

[0002] In recent years, there has been an increasing awareness of the environmental impact caused by traditional food packaging materials. The extensive use of non-biodegradable and non-recyclable packaging has led to significant waste generation and pollution, resulting in adverse consequences for our ecosystems. To address this pressing issue, the development of ecologically friendly food packaging solutions has become paramount. One promising approach is the use of composite materials that can be easily separated, enabling efficient recycling and reducing the environmental burden.

[0003] The objective technological problem of designing a novel packaging with separable composite materials revolves around achieving effective separation of the different components while maintaining the functionality and integrity of the packaging. Some specific challenges include:

[0004] Material Compatibility: Selecting composite materials that can be easily separated without compromising the overall performance and functionality of the packaging. The materials should have compatible properties, such as similar melting points or adhesion properties, to ensure proper separation during recycling or composting processes.

[0005] Mechanical Strength: Ensuring that the separable composite packaging maintains its structural integrity throughout its lifecycle, including handling, transportation, and storage. The packaging should be able to withstand mechanical stresses without compromising the separability of its components.

[0006] Barrier Properties: Maintaining the necessary barrier properties, such as moisture resistance, oxygen barrier, and aroma retention, to preserve the quality and shelf life of the packaged food. The separable composite materials should not compromise these critical attributes.

[0007] Manufacturing Efficiency: Developing manufacturing processes that allow for efficient and cost-effective production of the separable composite packaging. The manufacturing methods should be scalable and compatible with existing machinery and infrastructure.

[0008] Recycling Infrastructure: Considering the existing recycling infrastructure and facilities to ensure the separable composite materials can be effectively sorted, separated, and recycled. Compatibility with current recycling processes and technologies is crucial for widespread adoption and environmental impact reduction.

[0009] Consumer Acceptance and Education: Encouraging consumer acceptance and proper disposal practices through effective communication and education. Consumers need to understand the importance of separating the different components for recycling or composting and be aware of the environmental benefits associated with these actions. Large improvements can be made in this area.

[0010] A particular challenge is to use the various packaging materials, in particular biodegradable materials such as paper fiber-based packaging parts, with film-based packaging materials that are used for adequate product protection in such a way that they are also available for improved waste separation.

Summary of the Invention

[0011] To this aim, according to a first aspect of the invention, there is provided a packaging as set out in Claim 1, comprising a fiber-based packaging base, a product carrier film, that is adhesively attached to a front side of said packaging base such that it can be peeled from said packaging base without causing fiber-tear, a skin film, which fixates at least one product on the front side of said packaging base by adhering to said product carrier film by means of a sealing area that provides a sealable connection between said skin film and said product carrier film, said skin film and said product carrier film forming a composite in which said product is enclosed, said fiber-based packaging base together with said adhesively attached product carrier film is half cut along a folding line that is located outside said sealing area, and said fiber-based packaging base is half cut along an undulating line that is undulating along said folding line.

[0012] The fiber-based packaging base or packaging base referenced in this invention may be preferably a sheet of paper, cardboard, wood-fiber, bio-degradable polymers or similar material that is preferably bio-degradable since it is an object of the invention to provide for an eco-friendly packaging. The fiber-based packaging base preferably has a minimal thickness in order to provide the necessary rigidity and support for the product to be packaged. Since fiber-based materials often consist of highly compressed fibers, such a fiber-based sheet of material may intrinsically have a minimal thickness. Typical thicknesses of fiber-based compressed materials may range from a few tenths of a millimeter to a centimeter.

[0013] Also fiber-based materials may provide a certain capability to expand in areas where the material is bent or folded. When folding the material, the compressed material may fray out in the zones where the material is bent.

[0014] The fiber-based packaging base preferably consist of materials that provide the necessary rigidity and support to allow for the packaged product to maintain its shape after packaging, or that the packaged product may be stacked by means of the rigid packaging base. Fiber-based packaging materials tend to be less expensive since they mainly comprise recycled materials.

[0015] The product carrier film within the context of this invention has to be interpreted as a functional separating layer that prevents that the product comes into direct contact with the fiber-based packaging base material. The product carrier film is adhesively attached to the fiber-based packaging base.

[0016] The skin film in this invention is a plastic sheet that is pulled over the product which is positioned on the packaging base. The skin film is sealed by a sealable connection to the plastic material of the product carrier film. The sealable connection fixates the product on the front side of the fiber-based packaging base.

[0017] The fiber-based packaging base onto which the product carrier film is applied is preferably arranged with a first half-cut along a folding line. This first half-cut through the packaging base and product carrier film provides a folding line for folding back a corner or portion of the fiber-based packaging base while unpacking the product. Folding back means bending a corner or portion away from the front side of the packaging base, in other words bending away from the side where the product is located, in other words towards the back side of the packaging.

[0018] The fiber-based packaging base is preferably arranged with a second half-cut at the front side of the fiber-based packaging base material, and this preferably along an undulating or zig-zagging line that is undulating along the folding line mentioned above. This second half-cut through the packaging base alone provides an expansion line of the fiber-based packaging base while unpacking the product.

[0019] According to a second aspect of the invention a packaging is provided wherein the product carrier film is adhesively attached to said packaging base by means of an adhesive with a low peel strength. Peel strength, expressed in N/mm, is a measure of the adhesive's ability to resist being pulled apart or peeled away from a surface to which it has been applied. When the peel strength is low, it means that the adhesive may not effectively bond or stick to the surfaces it is meant to join. A peel strength may be considered low when between 0.1 N/mm (Newton per millimeter) and 1.0 N/mm. Such a low peel strength is advantageous in that it can guarantee peeling without fiber-tear.

[0020] According to a third aspect of the invention a packaging is provided wherein said fiber-based packaging base is coated, varnished, lacquered, impregnated or covered with another non-adhesive surface material on the front side such that said product carrier film can be peeled from said packaging base without causing fiber-tear.

[0021] According to a fourth aspect of the invention a packaging is provided wherein said folding line is applied in a corner of a polygon shaped fiber-based packaging base. This aspect is advantageous since this folding line configuration will result in the most accessible placement of the grip-area or grip-tab for the packaging.

[0022] According to another aspect of the invention, a packaging is provided wherein the undulating line is weaving across said folding line. This aspect of the invention is advantageous in that it offers an optimal positioning of the second half-cut with regards to the first half-cut that produces an optimal expansion of the fiber-based material in the area of the folding line. By providing a second half-cut that weaves over the first half-cut that forms the folding line, the small portions or pieces of the fiber-based material that are cut loose by the two half-cuts will expand the most, providing the desired expanding effect.

[0023] According to yet another aspect of the invention, a packaging is provided wherein said undulating line is not crossing over said folding line, and weaves in parallel alongside said folding line. This aspect provides an alternative half-cut positioning that yields a similar effect as above. Also here the small portions or pieces of the fiber-based material that are cut loose by the two half-cuts will expand the most, providing the desired expanding effect.

[0024] According to yet another aspect of the invention, a packaging is provided wherein at least one portion of said undulating line is fully cut. This aspect foresees that a part of a portion of any of the half-cuts are fully cut through the packaging base. This feature may further facilitate the action of folding back the packaging base by requiring less force to perform this action. In another aspect, in the most extreme case, at least one fiber-based packaging base element is punched out between said undulating line and said folding line. This configuration being advantageous that the folding along the folding line may require the least possible effort to bend back the corner portion of the fiber-based packaging base.

[0025] According to another aspect of the invention, a packaging is provided wherein the folding line comprises a protruding lobe shape providing a grip-tab for initiating peeling off said product carrier film from said fiber-based packaging base. In yet another aspect, the protruding lobe is 0,5-2cm in height.

[0026] According to another aspect of the invention, a packaging is provided wherein said skin film provides for a grip portion corresponding to said grip-tab for initiating peeling off said product carrier film from said fiber-based packaging base, allowing easy opening of said composite by separation of said skin film and said product. This aspect of the invention is advantageous in that the grip portion that is part of the skin film substantially aligns with the grip tab of the product carrier film that is cut-out by the first half-cut, such that both the grip-tab as the grip portion are gripped together by the user to remove the composite from the packaging base. And when the composite is separated from the packaging base, the grip portion and the grip-tab can be gripped separately in order to open the composite to remove the product, by splitting the composite in the two plastic portions, the product carrier film and the skin film.

[0027] According to another aspect of the invention, a packaging is provided wherein the sealing area substantially follows the contour of the skin film, except that a grip portion is excluded from said sealing area, such that said product carrier film can be separated from the skin film, by gripping both the grip portion from the skin film and the grip tab from the product carrier film. The grip tab thus corresponds to the portion or area of the skin film that is not included in the sealable area determined by the sealing area.

[0028] In the case of the known cardboard trays and cardboard blanks, however, a relatively large amount of foil material is consumed by the use of a first film for the complete lining of the cardboard tray or as a full-surface foil coating of the cardboard blank and a further skin foil designed as a lid. In addition, due to the material bond between the first film and the cardboard tray or cardboard blank used as a carrier, a relevant material separation is complicated and tends not to be carried out by the end user.

[0029] Preferably new packaging types will make it easier for a consumer to easily separate the different materials from each other in a clean and straight forward fashion. This means that the separation should lead to a preferably 100% separation into the composing material types, and this without too much hassle. Preferably, by opening the packaging to get to the product, the first steps are taken to separate the different material components of the packaging.

[0030] While encouragement of the public to improve its waste separation habits may change the behavior of a large audience on the long term, a better approach for obtaining better waste separation results would be to design packaging such that when a consumer opens the package, the correct separation of the different components is the automatic result.

[0031] The claimed invention is advantageous in that it allows for a clean separation of the different packaging materials. It is advantageous that the fiber-based packaging base can be removed without fiber-tear from the composite containing the product. Moreover, when opening the packaging of the invention, the consumer is obliged to first remove the composite from the packaging base in its entirety, before the composite containing the product can be opened. This ensures that all plastic material is separated from the fiber-based material. A further advantage of the invention is that the consumption of plastic material is minimized .

[0032] To this aim, according to another aspect of the invention, there is provided a method for separating respective packaging materials of a packaging according to independent method claim 13.

[0033] Another aspect of the invention is the manufacturing method according to method claim 14, wherein the manufacturing process of the packaging of the invention is provided.

[0034] Further advantages and embodiments of the present invention will become apparent from the following description and drawings.

Detailed Description of Embodiment(s)

[0037] In the following detailed description, reference is made in sufficient detail to the above referenced drawings, allowing those skilled in the art to practice the embodiments explained below.

[0038] In Figure 1, a top view of the front side of the packaging of the invention 10 is shown, the packaging of the invention comprises a packaging base 20, a product carrier film 40 and a skin film 60. The product carrier film 40 and skin film 60 are plastic sheet components that are sealed together to envelop the product P completely and form a so-called composite 70.

[0039] The shape and size of the product or products P to be packaged determines the size of the product carrier film 40 on which the product P is positioned, and therefore also the shape and size of the packaging base 20. Preferably, the size of the product carrier film 40 exceeds the size of the product P by at least the width of a contour that can serve as a sealing area 80 connecting the product carrier film 40 with the skin film 60. In one embodiment, the product carrier film 40 covers the entire surface of the packaging base 20. The size of the product carrier film 40 should ideally be limited to the amount of material needed to allow for a proper sealing area 80 to be foreseen between the two plastic layers in order to minimize the total amount of material used in the packaging, and to minimize packaging material consumption. In addition to this, extra material should be foreseen of the product carrier film 40 outside of the sealing area 80 to provide the grip-tab 95.

[0040] The product carrier film 40 is attached to the packaging base 20 by means of the adhesive layer that is foreseen on one side of the plastic sheet of the product carrier 40, and that is oriented towards the front side of said packaging base 20.

[0041] The front side of the fiber-based packaging base 20 may be treated such that an optimal adhesion is ensured between the fiber-based packaging base 20 and the product carrier film 40. The front side surface of the fiber-based packaging base 20 may be treated such that the adhesion with the product carrier film 40 is better controlled, in other words that the level of adhesion between the treated surface of the fiber-based packaging base and the product carrier film is controlled. To this extent, the front surface of the fiber-based packaging base may be coated, varnished, lacquered, impregnated or covered with another non-adhesive surface material. As such may the amount of coating, varnish or lacquer applied on the surface of the fiber-based packaging base control the level of adhesion between the product carrier and the fiber-based packaging base, and thus find a compromise between a good adhesion strength and the risk of occurrence of fiber-tear when separating the product carrier from the packaging base. Fiber-tear is an undesired effect wherein a portion of the fiber-based packaging base remains adhered to the product carrier when separating the product carrier from the packaging base. In other words, a portion of the fiber-based packaging base material remains attached to the plastic material of the product carrier film when fiber-tear occurs. This effect is preferably minimized in order to ensure optimal separation of the two materials.

[0042] The fiber-based packaging base 20 can be shaped into different shapes and forms, and may be adapted to shape, size and number of products to be packaged in order to minimize material consumption. The size and shape of the packaging base is chosen such that the packaged product(s) comfortably fit to its surface, but leaving at the same time sufficient space on the front side of the packaging base beyond the contour of the packaged products to allow for good adhesion between the product carrier film 40 and the skin film 60.

[0043] The fiber-based packaging base may be for instance shaped as a flat sheet or plate, a tray, a cup, as a rectangle or as another geometric shape. In general, the packaging base preferably provides a sufficiently large contact surface to accommodate the product carrier 40 on which the product or products P are arranged. The product carrier film may at the most assume the same surface and shape as the packaging base itself, but may also be smaller.

[0044] The product carrier film 40 serves as an impermeable layer that prevents liquid, moisture or product to come into contact with the fiber-based packaging base 20. Especially when the packaged product P comprises moisture or fat, such as a food product, a water and fat resistant barrier is preferably foreseen between the product and the fiber-based packaging base to prevent that this moisture or fat partially ingresses the fiber-based material, or that the moisture or fat is partially absorbed by the fiber-based material. The product carrier film 40 therefore is preferably made from plastic sheet material with an at least partially adhesive surface allowing it to adhere tightly to the front side of the packaging base. The front side of the packaging base 20 being the side that is facing the product P.

[0045] The skin film 60 is a plastic sheet that is pulled over the product P which is positioned on the packaging base 20. The skin film 60 is sealed by a sealable connection to the plastic material of the product carrier film. The sealable connection fixates the product on the front side of the fiber-based packaging base. The skin film may form a vacuum package together with the product carrier film. The plastic material of the skin film is preferably the same plastic material as the product carrier in order to form a composite consisting of the same material. The composite preferably fully encloses the product by means of plastic material, and forms a sealed plastic baglike enclosure. The two parts forming the composite may then be disposed of together.

[0046] The skin film 60 is sealed or welded to the product carrier film 40 in a so-called sealing area 80 that is an area that fully encircles the contact surface of the product to be packaged P and the product carrier film 40. The sealing area 80 is preferably sufficiently broad to ensure sufficient sealing quality and prevent leakage from within the composite.

[0047] However, in order to make a portion of the skin film 60 accessible to a user for gripping, a gripping portion 100 is foreseen of the skin film 60 that is kept outside the sealing area 80. The gripping portion 100 is therefore not welded to the product carrier film 40. The gripping portion 100 covers a portion of the product carrier film 40 having a protruding lobe shape providing a grip-tab 95 for initiating peeling off said product carrier film 40 from the fiber-based packaging base 20. The shape of the gripping portion 100 may be adapted to the shape of the grip-tab 95 as is illustrated in Figure 2. In case that the gripping portion 100 substantially aligns with the grip-tab 95, both present themselves as a single plastic tab portion of the composite 70.

[0048] In Figure 3, a side view of different parts of the packaging of the invention 10 is shown indicating the composite 70. The composite 70 consists of the product carrier film 40 and skin film 60. The composite 70 therefore ideally consists only of plastic material, and has a bag-like shape when removed from the packaging base 20, and that fully envelopes the product P.

[0049] Figure 4 shows another side view of the assembled packaging of the invention 10. The fiber-based packaging base 20 onto which the product carrier film 40 is applied is preferably arranged with a first half-cut along a folding line 90. The first half-cut therefore fully cuts the product carrier film 40, and partially cuts the fiber-based packaging base 20 along the same folding line 90 as indicated in the drawing. The folding line 90 is preferably arranged outside the sealing area 80, such that when the fiber-based packaging base 20 is bent backwards along the folding line 90, a portion of the product carrier film is released 41, shown in Figure 10, from the fiber-based packaging base 20 without further releasing the product carrier film from the fiber-based packaging base in the sealing area 80. This first half-cut 90 through the packaging base and product carrier film provides a folding line 90 for folding back a corner or portion of the fiber-based packaging base while unpacking the product P.

[0050] The fiber-based packaging base is preferably arranged with a second half-cut 91 at the front side of the fiber-based packaging base material, and this preferably along an undulating or zig-zagging line that is undulating along the folding line 90 mentioned above. This second half-cut 91 through the packaging base 20 alone provides an expansion line 91 of the fiber-based packaging base 20 while unpacking the product. The undulation or zig-zag pattern along the folding line 90 enlarges the cutting surface caused by the half-cut through the fiber-based material 20, and this specifically in the vicinity of the folding line 90 mentioned above.

[0051] Folding back the packaging base along this expansion line 91 causes the compressed fibers of the fiber-based material to expand 200 in the half-cut area, which results in lifting up of the product carrier film in this area.

[0052] The expansion of the fibers 200 in the area of the folding line 90 lifts up and liberates a grip-tab 95 portion of the product carrier film 40 that is situated between the first half-cut line 90 and the sealing area 80. This grip-tab 95 portion of the product carrier film 40 becomes readily accessible for a user opening the packaging 10 by folding back the corner or portion of the fiber-based packaging base 20. The grip-tab 95 can be easily accessed and gripped, and allows an easy separation of the product carrier film 40 from the packaging base 20. Since a portion of the skin film overlaps with the grip-tab, both plastic materials of the composite, being the combination of the product carrier firm and the skin film are necessarily removed simultaneously.

[0053] Figure 5 shows a top view of a detail of a corner of the packaging 10 of the invention showing an embodiment of the folding line 90 and an undulating line 91. The folding line 90 marks the path of the first half-cut through the product carrier film 40 that is adhesively attached to the packaging base 20. The folding line 90 is shaped comprising a protruding lobe 95, the protruding lobe having a height 96. Along this folding line 90, the product carrier film 40 is fully cut, and the packaging base 20 is half-cut, meaning that the fiber-based material of the packaging base 20 is not cut all the way through to the other side. This figure shows an embodiment where the position of the undulating line 91 is positioned more towards the center of the packaging base thank the folding line 90, but that both lines substantially touch each other.

[0054] Figure 6 shows a top view of a detail of a corner of the packaging 10 of the invention showing another embodiment of the folding line 90 and an undulating line 91. This figure shows an embodiment where the position of the undulating line 91 weaves across the folding line 90.

[0055] Figure 7 shows a top view of a detail of a corner of the packaging 10 of the invention showing another embodiment of the folding line 90 and an undulating line 91. This figure shows an embodiment where the folding line 90 is shaped as a straight line, without a protruding lobe 95.

[0056] Figure 8 shows a perspective view of a detail of a corner of the packaging of the invention in an early step of the production process. When producing the packaging of the invention 10, as a first step the fiber-based packaging base 20 is cut to its final intended size. In a next step, the second half-cut 91 is made to the packaging base 20 along the undulating line.

[0057] Figure 9 shows a perspective view of the same detail of a corner of the packaging of the invention in a next step of the production process. In this step, the product carrier film 40 is adhesively applied to the upper surface of the packaging base 20. In a next step, the first half-cut 90 is made to the combination of the applied product carrier film 40 and the packaging base 20 along the folding line 90. The result of the preceding steps is depicted in the configuration of Figure 9.

[0058] On this above configuration, the product P is positioned over which the skin film 60 is pulled. The skin film 60 is sealed onto the product carrier film 40 in the sealing area 80.

[0059] Figure 10, depicts the resulting configuration of the product carrier film 40 and packaging base 20, after the corner of the packaging is bent or folded backwards. Folding back the packaging base 20 along the expansion line 91 causes the compressed fibers of the fiber-based material to expand 200 in the half-cut area, which results in lifting up of the product carrier film 40 in this area, as is indicated by the upwards pointing arrows in the drawing. When the fiber-based packaging base 20 is bent backwards along the folding line 90, a portion of the product carrier film is released 41 from the underlying packaging base 20.

[0060] When opening the packaging, and in a first step, a corner of the fiber-based packaging base 20 is bent backwards along a folding line 90, revealing the grip-tab 95 which is a portion of the product carrier film 40. The expansion 200 of the fiber material liberates a portion 41 of the product carrier film by pushing it upwards, this portion is the grip-tab 95. The grip-tab 95 is covered by a gripping portion 100 of the skin film 60, and both present themselves as a single plastic tab portion of the composite 70. So, in order to proceed with the unpacking of the product, a user will have no choice but to separate the plastic material from the composite 70 first from the packaging base 20.

[0061] In a second step, the composite 70 consisting of the skin film 60 sealed to the product carrier film 40, is easily and cleanly removed from the fiber-based packaging base 20 by grabbing the combination of the grip-tab 95 and the gripping portion 100, and tearing both layers, skin film 60 and product carrier film 40 off from the packaging base 20. In this second step, the plastic materials are fully separated from the fiber-based material.

[0062] It is only after this second step that the skin film 60 can be separated from the product carrier film 40 to release the product from the composite 70. The product carrier film 40 is separated from the skin film 60 by separately pulling the grip-tab 95 and the gripping portion 100 to open the composite 70.
