Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a high strength oxygen permeability type beverage bottle PP packaging film, includes PP basic unit 1CPP layer 2, decorative layer 3, waterproof ventilative layer 4 and wearing layer 5, PP basic unit 1 be provided with transparent air cushion 12. Through the transparent air cushion 12, the consumer has certain elasticity when holding the beverage bottle, and the comfort level is improved. The surface fixed connection CPP layer 2 of PP basic unit 1, the fixed surface of CPP layer 2 is connected with decorative layer 3, and decorative layer 3 is polypropylene microporous filter membrane layer, and polypropylene microporous filter membrane layer is made by polypropylene. The polypropylene microporous filter membrane is made by hot-melting and bonding polypropylene superfine fibers together, belongs to a membrane material for deep filtration, and has the following characteristics: food-grade isotactic polypropylene is used as a raw material, and no additive is added in the whole production process; the physical and chemical properties are stable, and the compatibility is good; the filter has a series of pore diameters, high porosity and large pollutant carrying capacity, and can be used for back flushing and high-temperature disinfection; the pressure resistance is good. Better ink adsorption.
