Abstract (en)
[origin: WO7900170A1] Packing comprising one part of cardboard and a film of thermoformed synthetic material. A cardboard blank is cut up in the desired shape and grooved to allow the folding of its elements. Between the bottom (1) and the walls (8), a grooving line (18) is formed in the opposite direction to that of the known method to favour the expulsion of air during the thermoforming of the film (20). Between the walls (8) and the edges (16), a cutting up half-way down the thickness (19) is formed on the same face of the blank. The film (20) covers the cutting up (19) and maintains the walls as well as the bottom (1) despite of the wrong direction of the grooving (18). Packaging of various products, including food products.
