How are all biodegradable plastic bags made?

Plastic bags are something everyone knows more about. Basically, everyone touches and uses them every day. However, over the years, such things have been too obvious to our air pollution. It's like paying for environmental pollution and raising your own feet with a knife. With the announcement of the plastic restriction order, traditional plastic bags are not allowed to be used in all regions of China, and production and manufacturing are strictly prohibited. The application of all biodegradable plastic bags is fully promoted and the application of recycling system is advocated. So how are these plastic bags that can get marketing promotion from government agencies made? What characteristics does it have that can have such a great style.

After repeated deliberation and experiments, most biodegradable plastic bags can be divided into four processes: film blowing, inhibition of forming, packaging and printing, cutting and binding at the back. After the raw materials come in from the inlet, according to the extruder screw, after melting at high temperature and high pressure of 100 ℃, thin and thick are set according to the requirements. After annular air cooling, film blowing is carried out to form a thin and long plastic film cylinder. After cooling in the air, it is rolled to meet the processing of semi-finished products of biodegradable plastic bags, and then the rolled plastic is put on the machinery and equipment, The finished products are processed according to the process flow of setting, packaging and printing, pattern design, cutting and so on. This kind of plastic bag is different from the traditional plastic bag except for the raw materials. Most of the other production processes are similar. Only this kind of packaging bag is relatively soft, which needs a little attention in the cutting process. The key advantages also depend on raw materials. Most manufacturers use PBAT as raw materials because it is also a degradable material.
