1. Raw material preparation: First of all, you need to prepare raw materials for degrading plastics. This may include biodegradable polymeric materials such as starch, polylactic acid (PLA), polyhydroxyalkanoate (PHA), etc.
2. Material preparation: send the prepared raw materials into the mixer or extruder for melting and mixing to form a uniform plastic melt.
3. Extrusion molding: extrude the plastic melt into a film with a certain shape and size through the extruder. This can be achieved with a single layer extruder or a multilayer extruder, depending on the requirements of the product.
4. Bag making: The extruded plastic film is sent to the bag making machine, and the film is cut and sealed through heating and cooling steps to form the final form of the degradable plastic bag.
5. Printing and decoration (optional): According to needs, it can be printed and decorated on degradable plastic bags to add trademarks, logos and other information.
6. Packaging and quality inspection: The degradable plastic bags produced are packaged and quality inspected to ensure that they meet the relevant standards and requirements.
7. Finished product out of the warehouse: through warehousing and logistics, the finished product degradable plastic bags are exported to the warehouse and prepared to be sent to customers or sales channels.
