Plastic bags are widely used in our daily lives, and there is a high demand in shopping malls. Next, the plastic packaging factory will tell you the production process of plastic bags. The first process is mixing, which involves mixing one or more plastic raw materials or additives evenly through a mixing machine.
The process is the process of blowing film. The prepared PE raw materials are processed into plastic films by heating and melting, primarily using a film blowing machine for operation. After cooling, the granular plastic film forms the raw material film for manufacturing plastic bags.
Plastic film is blown into different widths and thicknesses according to customer order requirements, as well as whether it is embossed. The process is printing, where each plastic bag usually has a certain amount of text or image, and related printing operations are carried out during this process.
If the plastic bag does not have any text or images, and the plastic bag is transparent, then this process can be omitted. The process is sealing and cutting, where a roll of printed plastic film is cut and sealed, and a specific punching knife is used to form the plastic bag required by the customer.
