Raw Materials For Production Of Plastic Bucket Jan 29, 2018

Production of plastic barrels of the main raw material is polyethylene (POLYETHYLENE,PE), referred to as PE, ethylene is the accumulation of polymer organic compounds. Polyethylene is the world's recognized best contact food materials, non-toxic, tasteless, odorless, in line with food packaging hygiene standards. Polyethylene film, light and transparent, with moisture-proof, antioxidant, acid, alkali, gas tightness general, excellent thermal sealing performance, known as the "Plastic Flower" laudatory name, plastic packaging printing is the most important material.

Pvc

PVC for short, the formula for (CH2-CH2CL) n, is the most important vinyl polymer, is currently the world's second only to polyethylene plastic varieties, in the domestic production in plastic is ranked first. In the printing industry, often with PVC color calendering film and transparent glazing film production books, folders, tickets and other cover packaging decoration.

Shrink film

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

Low Density polyethylene

Low density polyethylene, referred to as LDPE, is the largest variety of plastic packaging printing industry in the world. The proportion is 0.92~0.93, can float in the water. Low crystallinity (60%), in the pressure 1000~3000kg/c㎡ polymerization, it is also known as high-pressure polyethylene. At 23 ℃, the density is about 0.92. The formability of calendering is poor, and it is suitable for blow molding process into tubular film. Suitable for food packaging, fiber products packaging, daily chemical supplies packaging. Marking of degradable plastic bags.
