Preferably, the breathable layer is made of ePTFE (expanded polytetrafluoroethylene), and the side surface of the breathable layer is provided with a plurality of uniformly distributed breathable holes.

Preferably, the PP base layer, the CPP layer, the breathable layer and the PET surface layer are formed by extrusion compounding.

Preferably, the CPP layer is a polypropylene film manufactured by adopting a casting process.

Preferably, the inside wall of PP basic unit is provided with the adsorbed layer, the adsorbed layer adopts the PE material.

Preferably, the side of the PET surface layer is provided with a decorative ink layer.

Compared with the prior art, the utility model provides the high-strength high-oxygen-permeability PP packaging film for the beverage bottle, which has the following beneficial effects:

1. this high strength high oxygen permeability type beverage bottle PP packaging film through the PP basic unit and the CPP layer that are equipped with, can increase packaging film's structural strength for packaging film is not fragile, and through the ventilative layer that is equipped with, ventilative layer adopts the ePTFE material, and the side on ventilative layer is provided with the bleeder vent, can increase packaging film's oxygen permeability.

2. This high strength high oxygen permeability type beverage bottle PP packaging film, through setting up the adsorbed layer on PP basic unit's inner wall, and the adsorbed layer adopts the PE material, can make the packaging film produce the outer wall that electrostatic adsorption comes the adhesion beverage bottle to make the difficult not hard up phenomenon that produces of packaging film.

The parts which are not involved in the device are the same as or can be realized by adopting the prior art, and the packaging film has high strength and oxygen permeability and has good pasting and fixing effects.
