Packaging for food products
The packaging has two sheets, one flexible (2) and other rigid or semi-rigid (1) which is essentially flat, both being joined at their edges with the exception of a mouthpiece including a seal (5, 6) for introducing the product to be packaged. Said seal is selected between adhesive means (5) with removable protective strip (6) and mechanical seal pressure. The constitution of the flexible sheet (2) is selected from a completely transparent material and a partially transparent material. The constitution of the rigid or semi-rigid sheet (1) is selected between a plastic material and a cardboard material laminated at least on its inner face. This allows advantageously replacing the classical non-planar, polystyrene or the like, trays.
