The Raw Material Of The Plastic Barrel
Jul 03, 2017

The main raw material for the production of plastic barrels is polyethylene (Polyethylene, PE), or PE, which is a polymer compound made of ethylene. Polyethylene is recognized as the world's best contact food materials, non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light transparent, with moisture-proof, antioxidant, acid, alkali, gas tightness general, thermal seal excellent performance, known as "Flower of Plastic" laudatory name, is the most important material in plastic packaging printing.

Pvc

PVC referred to as PVC, molecular formula (CH2-CH2CL) n, is the most important type of vinyl polymers, is currently the world's second largest plastic varieties, in the domestic production in the first place in plastic. In the printing industry, often with PVC color calendering film and transparent film production books and periodicals, folders, tickets and other wrappers packaging decoration.

Shrink film

Shrink Film (Shrinkfilm) is a thermoplastic plastic film that is stretched and directed during the production process and is contracted by hot air treatment or infrared irradiation during use. After heat treatment, the film is tightly wrapped in the packaging, the contraction force in the cooling stage to achieve the maximum value, and long-term preservation.

Low Density polyethylene

LDPE is the largest variety of plastic packaging printing industry in the world. The proportion is 0.92 ~ 0.93, can float in water. Low crystallinity (60%), in the pressure 1000 bulk polymerization, it is also called high pressure polyethylene. At 23 Shan, the density is about 0.92. The die-casting process is poor, and it is suitable to be processed into tubular film by blow moulding. Suitable for food packaging, fiber products packaging, daily chemical products packaging.
