The custom production of food packaging bags can be said to be a complicated and simple process. Why is it so contradictory to say that it is complicated and simple?

The first step is blown film Blown film is a plastic processing method

It refers to a plastic processing technology in which plastic particles are heated and melted and then blown into a film, which is the first step in the production of plastic bags. If it is a film blown out of new particles, the color is bright, clean and hygienic, the finished product stretches well, bears a large weight, and the quality of the plastic bag is good, so it can be used for food packaging.

The second step of color printing There are many ways of color printing, common printing methods are roller printing, gravure printing, screen printing.

Roller printing and gravure printing are to print the whole roll of blown plastic film, which is mechanical printing, with fast printing speed and suitable for mass production; if screen printing is used, the rolled film must be cut into individual pieces first, and then manually print. The printing speed is slow, but the plastic bags produced in this way have thick ink marks and strong three-dimensional effect.

The third step is to make bags. Roller printed and gravure printed films are generally ironed by bag making machines and cut into plastic bags; a single plastic block printed by screen printing must be ironed manually, and tools include electric soldering irons and heat sealing machines.

Traditional vacuum food packaging bags are difficult to deal with because they cannot be degraded by microorganisms, resulting in waste of land resources and environmental pollution, which has brought great pressure to human development and environmental protection. Green environmental protection food packaging bags can effectively solve the problem of environmental pollution. problem, which is very beneficial to the sustainable development of the environment.
