Abstract (en)
[origin: WO9855359A1] This invention relates to packages, and methods of packaging, having particular application for free-flowing solids material, such as powders, granulated material and the like. Free-flowing material is contained in a first container (2), mainly formed from substantially impermeable material but including one or more gas-permeable portions (4). The or each gas-permeable portion (4) may be in the form of a longitudinal strip or patch sealing engaged in or integrally formed with the substantially impermeable portion (5). The gas-permeable portion or portions enable the application of a vacuum to the interior of the first container (2) when closed. In the preferred form of package, the first container (2) may be enclosed within an outer container (3) of substantially impermeable material, which container is vacuum sealed. For the packaging of products having stringent hygiene requirements, such as milk powders, the vacuum may be applied to the inner container (2) first and the or each gas-permeable portion (4) sealed with sealing means prior to vacuum-sealing of the inner container (2) within the outer container (3). The packaging method may employ form-filling of the inner container to produce a rectilinear block product which is more conveniently stackable and transportable.
