Description

Multilayer separation PE film

Technical Field

The utility model relates to the technical field of PE films, in particular to a multilayer barrier PE film.

Background

PE film is the most simple polymer organic compound, and the most widely used polymer material in the world today. The PE film has the greatest advantages that the protected product is not polluted, corroded and scratched in the production, processing, transportation, storage and use processes, and the original bright and clean surface is protected.

For example, the Chinese patent with the application number of 202021787321.8 comprises a surface layer, a base layer and a bottom layer, wherein a flame retardant layer is arranged between the surface layer and the base layer, a heat insulation layer is arranged between the flame retardant layer and the base layer, a tensile layer is arranged between the base layer and the bottom layer, and an antifouling layer is arranged on one side, deviating from the base layer, of the surface layer. The flame retardant coating can limit the open flame of top layer to spread to the basic unit, and the insulating layer can reduce the heat of transferring to the basic unit, and tensile properties of PE membrane can be improved to the tensile layer simultaneously, avoids the PE membrane to be accidentally torn, and the clean and tidy degree on PE membrane surface can be kept to the antifouling layer.

However, the PE film cannot be torn off rapidly, and has high production cost and limitations.

Disclosure of Invention

In order to achieve the above purpose, the utility model provides a multilayer barrier PE film, which comprises a PE film body, wherein a tearing crease is arranged in the middle of the PE film body, the PE film body comprises a surface layer, a heat insulation layer and a base layer, and a plurality of air bubbles are connected to the outer surface of the surface layer.

Preferably, openings are formed in the left side and the right side of the PE film body, and the openings are connected with tearing crease marks.

Preferably, the upper end face of the PE film body is connected with a reserved crease, and the reserved crease is positioned at the front side of the tearing crease.

Preferably, the air bubbles comprise an outer surface layer with an arc-shaped cross section, and an inner cavity filled with air is arranged inside the outer surface layer.

Preferably, the lower end of the inner cavity is connected with an inner surface layer, and an air cavity filled with air is arranged in the inner surface layer.

Preferably, the tear crease is in a wavy arrangement.

Compared with the prior art, the utility model has the beneficial effects that:

according to the PE film, the PE film body is convenient to tear rapidly through the tearing crease, the PE film is convenient to use, and the articles packaged in the PE film body are effectively protected through the arranged air bubbles, so that the practicality of the PE film is improved.
