The polyethylene material for undershirt bags is milky white before processing, but after some primary processing, its form will be changed, for example, the material is translucent in the state of thin section, which is also the pre-molding state of plastic bags.
The polyethylene material used to make the undershirt bag has a very good durability, and it can also have its own characteristics in a certain Chengdu and within the range of life and chemical products. As we can find in the process of use, the undershirt bag material has a very good non-hygroscopic properties, and can be very good resistance to water vapor, which also greatly extends its field of use. Very special is the production of undershirt bags of this material has a very good electrical properties, at the same time, its insulation dielectric strength is also very high. It is worth mentioning that this material can be well used in different temperatures, which also greatly improves the use of undershirt bags.
