High Density Polyethylene (HDPE for short) is a non-polar thermoplastic resin with high crystallinity. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial or chemical preservation properties, and will produce chemical and acid resistant fermentation products….
