It is suitable for blowing low-density polyethylene (LDPE), high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE) and other plastic films. It is widely used in civilian and industrial packaging such as food, clothing, garbage bags, and vest bags. Low-density polyethylene films are generally made by blow molding and casting processes. The thickness of cast polyethylene film is uniform, but due to its high price, it is rarely used at present. High Density Polyethylene (HDPE) is a non-polar thermoplastic resin with high crystallinity. Linear low-density polyethylene has natural color, cylindrical or oblate particles, and the size of the particles should be 2-5mm in any direction. There is no metal or mechanical impurities. The structure is different from ordinary low-density polyethylene because it does not exist. Long chain branch.
