Embodiment 1

[0025] like figure 1 As shown, an easy-to-tear film for a plastic container includes a film body, the film body includes an inner film 1 and an outer film 2 compounded on the inner film 1, and the inner film 1 includes the following components: 60 to 70 weight 10-20 parts by weight of polypropylene, 10-20 parts by weight of ethylene-vinyl acetate copolymer, 10-20 parts by weight of ethylene-acrylic acid copolymer and 5-10 parts by weight of ionic polymer.

[0026] The inner membrane formed by polypropylene, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer and ionomer, due to the heating of polypropylene, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer and ionomer After melting, the inner membrane is not only physically bonded to the plastic container, but also has the ability to produce chemical bonds on the surface of the inner membrane. Since vinyl acetate and acrylic acid have acid radical bonds, both acid radical bonds and ionic bonds are...

Embodiment 2

[0030] An easy-to-tear film for a plastic container, comprising a film body, the film body including an inner film and an outer film on the composite inner film, the inner film comprising the following components: 62 parts by weight of polypropylene, 15 parts by weight of Ethylene-vinyl acetate copolymer, 17 parts by weight of ethylene-acrylic acid copolymer and 6 parts by weight of ionomer.

Embodiment 3

[0032] An easy-to-tear film for a plastic container, comprising a film body, the film body including an inner film and an outer film compounded on the inner film, the inner film comprising the following components: 62 parts by weight of polypropylene, 14 parts by weight of Ethylene-vinyl acetate copolymer, 16 parts by weight of ethylene-acrylic acid copolymer and 8 parts by weight of ionomer.

Abstract

The invention relates to an easy-to-tear film for a plastic container. The easy-to-tear film for the plastic container comprises a film body; the film body comprises an inner film; the inner film comprises the following components in parts by weight: 60-70 parts of polypropylene; 10-20 parts of an ethylene-vinyl acetate copolymer; 10-20 parts of an ethylene-acrylic acid copolymer; and 5-10 parts of an ionic polymer. According to the method, after the polypropylene, the ethylene-vinyl acetate copolymer, the ethylene-acrylic acid copolymer and the ionic polymer are heated and melt, the inner film is in contact with the plastic container, physical combination is realized; chemical bonds can be generated on the surface of the inner film, and therefore, the easy-to-tear film can be used for sealing various plastic containers at the same time; one material can be used for replacing various materials, so that the flexibility of the product in later use is greatly improved. In addition, the invention further discloses a preparation method of the easy-to-tear film for the plastic container. The preparation method is used for preparing the easy-to-tear film for the plastic container.

Description

technical field [0001] The invention relates to an easy-tear film for a plastic container and a preparation method thereof. Background technique [0002] The sealing film is mainly used for the sealing of container packaging products, and has airtightness and moisture resistance. At the same time, because it is a disposable product, it also has certain anti-theft and anti-pollution properties. Among them, the easy-to-tear sealing film can be peeled off smoothly, so that the packaging will not be spilled and cause unnecessary waste, and it does not require a lot of effort in the tearing process, which is more convenient for people's lives. Therefore, easy-to-tear parafilm is becoming more and more a trend in the market. The current easy-to-tear sealing film is basically formulated according to the material of the plastic container, and a sealing film matching its performance is formulated. Such plastic containers of different materials need to customize the sealing film co...
