 One is PE, which is mainly used to wrap heavy objects, such as optical cables, pipes, and whole packages of cola. Most of the materials coming out are tubular materials. Inspection specifications also depend on clarity and purity? Is the film uniform?

The second type is POF, which is made of compressed rock and usually comes out with bags. If using tubular materials, the order quantity should be several tons or more. Conventional color: Tongming. Printing can be done as required. Products are mainly used in packaging of pharmaceuticals, cosmetics, disinfected tableware, etc. Inspection specification: Is it an opening when shortening? Does printing fade? Visibility?

The third type of PVC, which is made by blow molding, usually comes out of coiled materials. (It can also be made into bags or cut into single search cylinders based on customer needs.) The colors commonly used are sapphire and light green. The thickness is usually 5 threads. PVC film is currently the most widely used film material. It is inexpensive, has a large scale of temperature reduction, and has a low demand for heat sources. The primary processing heat source is hot air, infrared, or a combination of the two. However, PVC is difficult to recover and generates toxic gas during incineration, which is not conducive to environmental protection. Its use has been banned in Europe and Japan. The first thing to check is: Is there a node in the transparency, glossiness, and film? Is the film uniform?
