How to make biodegradable plastic bags?
Whether it is a normal plastic bag or a biodegradable plastic bag, their production process is roughly similar. First, you need to use a blown film extrusion machine to blow the plastic raw material into plastic film. The plastic film is then made into plastic bags using a bag making machine. If you need to print a pattern on a plastic bag, you need to use a printing machine to print the pattern on the plastic film before making the bag. Compared with the production of ordinary plastic bags, the production of biodegradable plastic bags requires the use of degradable plastic materials to make plastic films. For example, PLA, PBAT, corn starch and other degradable plastic materials. Since plastics are difficult to degrade naturally, with the introduction of plastic restriction orders in various countries, many plastic processors have turned to the processing of biodegradable plastics. Products processed from biodegradable plastics can be completely decomposed by environmental microorgan...
