Easily-uncover aluminum plastic compound single film for glass bottle sealing opening

Abstract

The invention relates to an easily-uncover aluminum plastic compound single film for a glass bottle sealing opening. The film comprises a body, wherein a compound layer, a base layer, and a heat sealing layer are arranged on the body in sequence; a blocking layer is arranged on the compound layer; the body comprises the components in percentage by weight: 29.47%-30.59% of low-density polyethylene, 39.05%-40.81% of linear low-density polyethylene and 29.72-30.36% of an ethylene-(methyl) acrylate copolymer. The film has the advantages that the low-density polyethylene, the linear low-density polyethylene and the ethylene-(methyl) acrylate copolymer are mixed for preparing the body, so that the glass bottle sealing opening is proper in fastness, and is proper in stripping force when being uncovered; a stripping interface is clean, an obvious attenuation phenomenon after refrigeration does not exist, and the film is wide in application range of packaged products; due to arrangement of the blocking layer, the body has the very good blocking performance, stiffness and forming performance, the blocking layer can enable the packaged products to obtain very good protection, the stiffness enables the compound film to be conveniently cut into single pieces, the forming performance enables pressing lines to be processed and arranged conveniently, and the use effect is good.

Description

technical field [0001] The invention relates to an aluminum-plastic composite monolithic film which can be easily opened for sealing glass bottles. Background technique [0002] There have been glass bottles in our country since ancient times. In the past, academic circles believed that glassware was very rare in ancient times, so only a few ruling classes could own and use them. However, recent studies have concluded that the production and manufacture of ancient glassware is not difficult, but it is not easy to preserve, so it is rare to see it in later generations. Glass bottle is a traditional beverage packaging container in our country, and glass is also a kind of packaging material with a long history. With many kinds of packaging materials pouring into the market, glass containers still occupy an important position in beverage packaging, which is inseparable from its packaging characteristics that cannot be replaced by other packaging materials. [0003] The main ch...
