- the fluidity index is calculated according to ASTM D1238 standard.
- the density of the polyethylene used for layers 36 and 38 is preferably between 0.920 and 0.940.
- this density is between 0.930 and 0.936. It is preferably substantially equal, for example, to 0.933.
- layers 36 and 38 are formed from LDPE (polyethylene low density), LLDPE (linear polyethylene), MDPE (polyethylene medium density) or an ionomer (for example "SURLYN” sold by Dupont de Nemours), a mixture of these products, or polypropylene (homo or copolymer).
- LDPE polyethylene low density

- the cover 14 is separated from the tray 12, following at least part of the length of the rim 22. It forms a welded bead denoted 40.
- the layer of permanent adhesive 28 breaks in its intermediate part or delaminates at its interface with the film 24 or film 26.
- part, denoted 42, of the layer of permanent adhesive remains on the welded bead 40, while the complementary part, noted 44, remains on the support film 24.
- the two complementary parts 42, 44 each have a thickness substantially equal to half the thickness total of layer 28.
- a packaging sheet as described here and comprising a layer forming a barrier to gases and to molecular migrations interposed between the layer of permanent adhesive and a sealant layer suitable for sealing with the complementary part of the packaging the foodstuffs contained in the packaging do not have their degraded taste and / or olfactory properties.
- the cover is obtained by association of films extruded separately, these being linked to each other in particular by collage.
- the cover is formed by coextrusion of the different films, the layers constituting the welding film then being coextruded simultaneously with the other films of the cover.
- the laminated sheet has a layer permanent adhesive only in areas to be welded on the edge of the tray.
- the support film and the weldable film are linked to each other by a layer of glue of any suitable type.
- the sheet according to the invention is described here applied to the obturation of a tray. However, it could be used to form a resealable bag. In the latter case, the permanent adhesive can also be placed only in the sealing areas of the bag.
- a barrier layer integrated into the weldable film also provides a solution to the problem the ineffectiveness of a possible barrier layer when it is arranged, as is the case in the prior art, on the side of the film base relative to the layer of permanent adhesive.
- the layer forming a barrier to gases and molecular migrations is arranged on the inner side of the package relative to the layer permanent adhesive, even if this layer is delaminated, the layer forming barrier to gases and molecular migrations remains maintained over the entire surface of the packaging opening since this layer forming a barrier to gases and molecular migrations is integrated in the welding film.
- the layer forming barrier to gases and molecular migration is formed of polyester or copolyester. These are advantageously formed from copolyester amorphous.
- the amorphous copolyester used is of the PETG type or PCTG.
- the amorphous copolyester of the PETG type is an amorphous polyester obtained from terephatalic acid and a pre-eminent mixture of ethylene glycol with, in a lesser amount by mole of 1,4-cyclohexanedimethanol.
- PCTG type amorphous polyester is an amorphous polyester obtained from terephthalic acid and a pre-eminent mixture of 1,4-cyclohexanedimethanol with, in a lesser amount by mole of ethylene glycol.
- the welding layer and the layer forming barrier to gases and molecular migrations are advantageously a one and the same layer.
