Embodiment

[0028] A kind of preparation method of high barrier performance anti-expansion packaging bag of the present invention, it comprises the following steps,

[0029] 1. Inner bag making:

[0030] (1) LLDPE / LDPE, PET and TPU are blown into PET film through a three-layer co-extrusion film blowing machine. The temperature is controlled between 150-170°C, the frequency of the host is between 25-35Hz, and the traction frequency is 8- 10Hz, and then through the laminating machine, use the adhesive to laminate the PET film on both sides of the aluminum foil, and then cut the laminated aluminum film into pieces;

[0031] (2) Blow LDPE, TiV, and PA into five-layer co-extruded PA film through a five-layer co-extrusion blown film machine. 8-10Hz, then cut into film strips with a width of 5cm and the same length as the mesh spacer;

[0032] (3) Melt and extrude the PP particles, the melting temperature is between 140-150°C, and form a film by cooling, the film is punched by a die to form a ...
