Nowadays, there are many plastic bags, and the types of plastic bags are constantly increasing. In order to strengthen environmental protection, all-bio-plastic bags are used. For all-bio-degradable plastic bags, many people wonder how to make all-bio-explanatory plastic bags?

After repeated scrutiny and testing, most of the biodegradable plastic bags can be divided into four processes: film blowing, suppression of forming, packaging and printing, cutting and bundling at the back. When the raw material comes in from the feed inlet, according to the extruder screw, after being melted by the high temperature and high pressure of 100 degrees Celsius, the thickness is set according to the requirements, and the film is blown into a circular air-cooled form to become a thin and long plastic. The film cylinder, after being cooled in the air, is rolled to meet the semi-finished processing of biodegradable plastic bags, and then the rolled plastic is placed on machinery and equipment, and finished products according to the process of shaping, packaging and printing pattern design, and tailoring. This type of plastic bag is different from the traditional plastic bag except for the raw materials. The other production processes are mostly similar, except that this type of packaging bag is relatively soft and requires a little attention during the cutting process. The key advantage also depends on the raw material. Most manufacturers use PBAT as a raw material because it is also a degradable material.
