Embodiment approach 1

[0117] This embodiment is shown schematically in figure 1 middle. The embodiment consists of the following:

[0118] Outer layer 20 made of CPP,

[0119] the first adhesive layer 50,

[0120] carrier layer 34 made of BOPP,

[0121] The oxide material barrier layer 32 made of SiOx,

[0122] The second adhesive layer 50,

[0123] Inner layer 10 made of CPP.

[0124] Laminate 1 is obtained by adhesive lamination of these various layers. The outer layer 20 has a thickness of 100 μm. Carrier layer 34 and barrier layer 32 of oxide material represent barrier layer 30 . The SiOx barrier layer 32 has a thickness of less than 0.1 μm. The barrier layer has a thickness of 20 μm. The inner layer 10 has a thickness of 100 μm. Laminate 1 had a total thickness of 228 μm.

Embodiment approach 2

[0126] The embodiment consists of the following:

[0127] The surface layer 24 made of CPP,

[0128] The core layer 22 made of CPP,

[0129] The surface layer 24 made of CPP,

[0130] the first adhesive layer 50,

[0131] carrier layer 34 made of BOPP,

[0132] The oxide material barrier layer 32 made of SiOx,

[0133] The second adhesive layer 50,

[0134] Surface layer 14 made of CPP,

[0135] The core layer 12 made of CPP,

[0136] Skin 14 made of CPP.

[0137] Laminate 1 is obtained by extrusion lamination of these various layers. The skin layer 24 and the core layer 22 represent the outer layer 20 . Each of the skin layers 24 has a thickness of 10 μm, and the core layer 22 has a thickness of 80 μm. Therefore, the outer layer 20 has a thickness of 100 μm. Carrier layer 34 and barrier layer 32 of oxide material represent barrier layer 30 . The SiOx barrier layer 32 has a thickness of less than 0.1 μm. The barrier layer has a thickness of 18 μm. The skin layer ...

Embodiment approach 3

[0139] This implementation: mode is shown schematically in figure 1 middle. The embodiment consists of the following:

[0140] Outer layer 20 made of CPP,

[0141] the first adhesive layer 50,

[0142] carrier layer 34 made of BOPP,

[0143] The oxide material barrier layer 32 made of AlOx,

[0144] The second adhesive layer 50,

[0145] Inner layer 10 made of CPP.

[0146] Laminate 1 is obtained by extrusion lamination of these various layers. The outer layer 20 has a thickness of 100 μm. Carrier layer 34 and barrier layer 32 of oxide material represent barrier layer 30 . The AlOx barrier layer 32 has a thickness of less than 0.1 μm. The barrier layer has a thickness of 16 μm. The inner layer 10 has a thickness of 100 μm. Laminate 1 had a total thickness of 224 μm.

Abstract

A flexible tube skirt (200) formed by rolling a sheet (100) of a recyclable polypropylene (PP) based laminated material (1), said laminated material (1) comprising an inner layer (10) comprising PP, an outer layer (20) comprising PP and an barrier layer (30) 5 comprising an oxide material barrier (32) and a carrier layer (34) coated by said oxide material barrier (32), said carrier layer (34) being made of PP, the inner layer (10) having an higher ability to flow than the carrier layer (34).

Description

technical field [0001] The present invention relates to a laminate for forming a container, and more particularly to a flexible skirt comprising the laminate. Background technique [0002] Today, global plastic production is one of the largest sources of waste. The recycling of these plastic products is a major concern of national and regional organizations. Currently, non-recyclable plastic materials are disposed of through a variety of processes, ranging from landfill disposal to energy recovery through thermal and chemical treatment. [0003] In the cosmetic packaging industry, laminates comprising multiple layers are widely used because of their advantages in product protection and mechanical properties. [0004] In particular, aluminum barriers are often employed to improve impermeability. The aluminium layer is firmly bonded to the plastic material layer. This would create problems for the recycling of laminates as the plastic material and aluminium cannot be easil...
