Problems solved by technology

In the corona discharge treatment method, although higher treatment intensity can make the surface more active and improve the bonding strength between the metal film and the surface layer of the base material film, it is well known that this simultaneously degrades the base material, so the described The surface layer of the matrix material film may be detached from the interior of the matrix material film

Embodiment 1

[0041] A three-layer polyethylene outer film with a total thickness of 120 μm is in contact with an ethylene acrylic connection layer with a thickness of 25 μm. The tie layer bonds the polyethylene layer to a metalized ethylene acrylic layer that is also 25 μm thick. The metalized ethylene acrylic acid layer is in contact with another multilayer polyethylene film with a combined thickness of 75 μm. The multilayer polyethylene film is bonded to the multilayer sealant layer by an extruded polyethylene layer with a thickness of 25 μm. The structure of the metalized polyethylene laminate is as follows:

[0042] 30μm PE / 60μm PE / 30μm PE / / 25μm EAA (tie layer) / / Metalized 25μm EAA film / 50μmPE / 25μm PE / / 25μm extruded PE (tie layer) / / 12.5μm PE / 25μm PE / 12.5μm PE.

Embodiment 2

[0044] A double-layer polyethylene outer film with a total thickness of 90 μm is in contact with a metalized ethylene acrylic acid layer with a thickness of 30 μm, which is in turn bonded to the thickness by an ethylene acrylic acid connecting layer with a thickness in the range of 20 μm to 30 μm Another metallized ethylene acrylic layer of 30 μm. The two-layer polyethylene inner film with a thickness of 90 μm is in contact with the metalized ethylene acrylic acid layer.

[0045] The structure of the metalized polyethylene laminate is as follows:

[0046] 30μm PE / 60μm PE / metalized 30μm EAA / / 20μm to 30μm connecting layer or adhesive layer (EAA) / / metalized 30μm EAA / 60μm PE / 30μm PE.

Abstract

The present disclosure provides a metallized polyethylene laminate comprising: an outer polyethylene layer; a metallized acid copolymer layer; an inner polyethylene layer in contact with the metallized acid copolymer layer; and optionally an extruded polyethylene layer; and a sealant layer of polyethylene.

Description

Technical field [0001] The invention relates to metallized polyethylene laminates. The metallized polyethylene laminate of the present invention can be made into products for storing items that need to maintain texture and smell, such as food and cosmetics. Compared to articles made from laminates known in the prior art, the articles exhibit enhanced vapor and / or gas barrier properties. The present invention further relates to a method of manufacturing the metalized polyethylene laminate. Background technique [0002] Laminates are generally used in large quantities for the packaging and distribution of various products including personal care products and food. Due to inherent properties such as mechanical and physical properties, light weight, durability, non-toxicity, light and heat resistance, and chemical inertness, laminates are usually made of plastic polymers. The above properties make laminates a suitable choice for applications in the packaging industry. [0003] A me...
