Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to an EPE protective film with a wear-resistant function. Background Art

[0002] EPE generally refers to pearl cotton. Polyethylene foam is a non-cross-linked closed-cell structure, also known as EPE pearl cotton. It is a new type of environmentally friendly packaging material. EPE has many advantages such as waterproof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc. It also has good chemical resistance, so it is widely used.

[0003] According to a disclosed composite EPE plastic protective film (publication number: CN214324463U), in the above application, a protective cushion layer made of foamed EPE material is provided, so that the plasticity and toughness of the protective film are extremely strong, and cross-distributed reinforcing steel wires are provided inside the protective cushion layer to improve the strength of the protective cushion layer and improve the tear resistance.

[0004] However, during the use of this protective film, its horizontal tensile strength and deformation recovery capabilities are limited. In particular, when the protective film is subjected to lateral friction, the EPE protective film is prone to lateral displacement, and the steel wire that serves as a shape-maintaining function cannot effectively prevent the deformation of the protective film and restore it, reducing the EPE protective film's wear-resistant protection ability during protection. In view of this, we propose an EPE protective film with wear-resistant function. Utility Model Content
