Description

Technical Field

[0001] The utility model relates to the technical field of films, in particular to a high-barrier biaxially stretched film. Background Art

[0002] High barrier film is made by simultaneously extruding a material with strong gas barrier properties and a polyolefin with strong heat-sealing and moisture barrier properties. It is a multi-layer polyethylene film, which refers to a film produced with PE film. PE film is moisture-proof and has low moisture permeability. Polyethylene film (PE) can be manufactured into products with different properties such as low-density, medium-density, high-density polyethylene and cross-linked polyethylene according to different manufacturing methods and control methods. Biaxially oriented polyethylene film is made of special LLDPE raw material and is stretched longitudinally and then transversely. It has greatly improved physical properties compared to polyethylene films produced by original blow molding or cast film methods. It has high transparency, heat sealability, good moisture resistance, good longitudinal and transverse tensile strength, and has the advantages of moisture resistance and foldability. Especially when the thickness is reduced by 50%, the key performance still reaches the performance of other polyethylene films.

[0003] For example, a high-barrier biaxially oriented polyamide film disclosed in the authorization announcement number CN 210553485 U actually includes a first surface layer, an intermediate layer and a second surface layer, and the aluminum-plated layer covers the first surface layer. However, it does not solve the problem that the previous high-barrier biaxially oriented film is often designed with a single structure, poor ductility, short service life and easy breakage.
