AI Technical Summary

Technical Problem

The existing PE stretch wrap film is prone to accidental breakage due to its tear lines and tear holes, which affects the packaging effect.

Method used

The composite structure consists of a unidirectional easy-tear film layer, a self-adhesive film layer, an antistatic film layer, and an adhesive layer. The unidirectional easy-tear film layer is designed to be easy to tear along its width and difficult to tear along its length. Tear openings are made at equal intervals on the unidirectional easy-tear film layer. The self-adhesive film layer provides a self-adhesive effect, and the antistatic film layer provides an antistatic effect.

Benefits of technology

It achieves secure wrapping and quick tearing of items, improves the effectiveness of stretch film, and avoids accidental breakage of stretch film during use.

Abstract

The utility model relates to a wrapping film technical field especially relates to a kind of PE stretch wrapping film, including hollow reel and the PE film body wound on its outside, PE film body includes the unidirectional easy-to-tear film layer as intermediate layer, the inside of unidirectional easy-to-tear film layer is compounded with self-adhesive film layer by first adhesive layer, the outside of unidirectional easy-to-tear film layer is compounded with antistatic film layer by second adhesive layer;The width of self-adhesive film layer and antistatic film layer is equal and the both ends of width direction alignment, the both ends of unidirectional easy-to-tear film layer along width direction are outward bulging relative to self-adhesive film layer or antistatic film layer, and the protruding part equidistance is provided with several tear openings.The utility model designs the width direction of unidirectional easy-to-tear film layer as easy-to-tear direction, length direction is designed as difficult tear direction, so that wrapping film can firmly wrap article, simultaneously tear opening of unidirectional easy-to-tear film layer can be used to realize the quick tearing of wrapping film along width direction, and use effect is better.
