Problems solved by technology

Another consequence of this is that the pouches thus formed cannot be sealed
This is because this delamination can also be accompanied by a rupture of the metal layer, with the risk that the existing product escapes from its packaging, and that the gases, solvents or aromas present therein disperse from the capsule, in all cases There is a phenomenon of gas penetration, resulting in product deterioration and cannot be used
In these cases, long-term corrosion protection of the product cannot be guaranteed

Embodiment Construction

[0059] figure 1 Shown is a material 1 in the form of a layer that crosses its thickness; this material 1 forms a multilayer composite with a layered structure, which includes at least the following layers superimposed on each other in the following order:

[0060] -Metal layer 4,

[0061] -An adhesive 5 comprising a copolymer containing at least 7% by weight of carboxyl and / or carboxylate units, the carboxyl units may be in the form of acid or salt, and

[0062] -The non-metallic material layer forming the first outer layer structure 6.

[0063] Preferably, when the material 1 is selected to package the product, the non-metallic material 6 layers form the first outer layer structure 6 suitable for contact with the product, and the metal layer 4 is covered by the second outer layer structure 2 on the reverse side, the first outer layer Structure 6 is located on the opposite side of the second outer structure.

[0064] The second outer layer structure 2 may be made of one or more ...

Abstract

The invention relates to a packaging device comprising: i) at least one film at least partially delimiting a casing, said film constituting a multilayer composite (1) comprising: a) a metal layer (4); b) an adhesive comprising a copolymer A mixture (5), the copolymer comprising at least 7% by weight of carboxyl and / or carboxylate units, the carboxyl units may be in acid form or in salt form, and c) bonded to the metal by the adhesive A layer of non-metallic material on the layer (6); ii) a cosmetic composition within the housing.

Description

Technical field [0001] The subject of the present invention relates to a packaging device prepared at least in part from layers formed by a multilayer composite, which makes it possible to package products that are sensitive to light, gas and / or moisture. Background technique [0002] It is known to use packaging materials to protect such sensitive products. A particularly suitable packaging material is provided in the form of a sheet that can surround the product, regardless of its size. For example, these sheets can be adjusted to form flexible bags or pouches surrounding the product. [0003] In order to make this type of packaging material impermeable to light, air and water vapor, the material made of the packaging material must have at least one barrier forming layer. A particularly suitable barrier forming layer may be composed of, for example, a metal layer. Since the metal layer cannot meet all the requirements of the packaging material, in practice, other layers, especi...
