We all know that HDPE is a very high density material, and it also happens to be one of the main materials for making undershirt bags. This polyethylene material (HDPE) has a very good hardness, although in the production process there is a certain degree of difficulty and technically stringent requirements, but the resulting product has a very good nature, as well as very good performance.
HDPE material itself has a very good stability, so this is also to a large extent to ensure that the plastic bag in the use of the situation. The material used to make the undershirt belt is a very high crystallinity and non-polar thermoplastic resin material, no matter in the material storage stage, or in the production to the use of the stage has a very good safety and convenience, for the user is very good.
