Problems solved by technology

[0002] At present, multi-layer packaging materials have the following disadvantages: when the package is sealed, high-frequency heating welding must be used for the aluminum foil, which increases the equipment requirements; the aluminum foil cannot be bonded with high-strength linear polyethylene, and can only be bonded It is bonded by polyethylene, so the strength of this packaging material is low; aluminum foil and polyethylene must be bonded together by special glue, and special glue is expensive; this kind of packaging material cannot be directly used for beverages in microwave ovens. Heating; due to the low strength of aluminum foil, it is easy to be broken during processing, so the processing technology is complicated; in the recycling process, it can only be incinerated, which is not conducive to environmental protection

Abstract

The invention discloses a multilayer composite packaging material. An aluminum layer is arranged on a polyethylene layer, two polypropylene layers are arranged on the aluminum layer, and the surface of the outer polypropylene ethylene layer is coated with a layer of ultraviolet radiation cured membrane. The multilayer composite packaging material provided by the invention has strong adhesion and large buffering damping functions. The packaging product prepared from the packaging material has high strength and good impact resistance, thus being conducive to protecting the appearance quality of packaged objects.
