What is the wear resistance of PVC blanket packaging bag?

The wear resistance of PVC blanket packaging bags depends on the quality of its manufacturing process and materials. Generally speaking, PVC blanket bags have a certain wear resistance and can withstand a certain amount of friction and pressure. However, if the manufacturing process is poor or the material quality is poor, it may lead to a decline in the wear resistance of the PVC blanket bag.

In order to improve the wear resistance of PVC blanket packaging bags, methods such as increasing the thickness of the bags, adding anti-wear agents or surface treatment can be used. These methods can improve the wear resistance of PVC blanket packaging bags to a certain extent, so that it can better protect the blanket from wear and damage.

It should be noted that the wear resistance of PVC blanket packaging bags is still limited and cannot be compared with some high-quality polyethylene or polypropylene other plastic materials. Therefore, when using PVC blanket packaging bags, care should be taken to avoid excessive friction and pressure to protect the blanket from damage.

What are the manufacturing processes of PVC blanket packaging bags?

The manufacturing process of PVC blanket packaging bag mainly includes the following steps:

Ingredients: According to the production requirements, PVC resin, plasticizer, stabilizer, filler and other additives are mixed according to a certain proportion, stirring evenly.

Plasticizing: The mixed raw materials are put into the extruder, heated and melted to make it a uniform melt.

Film blowing: the melt is blown into a film by the film blowing machine, and the thickness and width of the film are controlled by adjusting the film blowing process parameters.

Printing: Printing patterns and text on the film can be done by intaglio printing, flexographic printing or inkjet printing.

Cutting: According to the requirements of the printed film cut into a certain size of the bag, you can use manual or automatic cutting equipment.

Packing: The cut bags are arranged, folded and packed for transport and sale.

The above is the main step of the PVC blanket packaging bag manufacturing process, each step has its own specific technical requirements and process parameters, which need to be strictly controlled to ensure the quality of the bag and the stability of production.
