Manufacturing Method And Raw Material Description Of Bottle Cap Gasket

The bottle cap gasket is stamped on the basis of PE, PS (blown paper) foam material, and is suitable for various wines, cosmetics, food, medicine, agricultural drugs, etc., and the inner sealing gasket of the bottle cap.

Polyethylene is a high polymer chain connected by repeating -CH2- units through the addition reaction and polymerization of ethylene (CH2=CH2). The properties of polyethylene depend on the way it is polymerized; high-density polyethylene (HDPE) is produced by Ziegler-Natta polymerization under moderate pressure (15-30 atmospheres) catalyzed by organic compounds. The polyethylene molecules polymerized under this condition are linear, and the molecular chain is very long, and the molecular weight is as high as several hundred thousand. If it is radically polymerized under high pressure (100-300MPa), high temperature (190-210 C), and peroxide-catalyzed conditions, low-density polyethylene (LDPE) is produced, which is a branched structure.
