Film blowing machine definition

definition
The film blowing machine heats and melts plastic particles and then blows them into a film.

There are many types of film blowing machines, including PE, POF, etc.

The material blown out with brand new particles has uniform color and luster, clean, and the bag is well stretched.

Some people also use recycled plastic bags to make particles. This kind of particles is generally called old material. When it is made into particles, it is usually gray. When making bags, pigments are usually added. The bags are unevenly colored, brittle and easy to break. , the price is also lower.

Although they are recycled plastic bags, they are generally waste bags in the bag making process. There is a big difference between them and ordinary garbage plastics.

composition
The film blowing machine consists of nine parts: ① motor, ② cylinder, ③ head, ④ dies, ⑤ v plate, ⑥ counter wheel, ⑦ smooth wheel, ⑧ counter wheel 2, ⑨wind

The temperature of raw material LLDPE and LDPE is 160--180 degrees

HDPE temperature is 210-230 degrees

The most important factors for the work of film blowing machine are three factors

1. Temperature (machine temperature, indoor temperature)

double helix

Three cooling systems

application
The film blown by the film blowing machine is suitable for various high-end film packaging. This kind of film can be widely used in light and heavy packaging due to its good barrier properties, preservation, moisture-proof, frost-proof, oxygen-proof and oil-resistant. Such as various fresh fruits, meat products, pickles, fresh milk, liquid drinks, medical supplies, etc.
