2. container

A. The use of plastic bottles, barrels, cans and hose containers of high and low density polyethylene and polypropylene-based, but also useful polyvinyl chloride, polyamide, polystyrene, polyester, polycarbonate and other resins The This type of container capacity can be as little as a few milliliters, as large as several thousand liters. Chemical resistance, air tightness and good impact resistance, light weight, easy transportation, low damage rate. Such as polyester blown film vials, low permeability, can withstand the pressure, has generally come to drink drinking water, soft drinks and other beverages.

B. Cups, boxes, plates, boxes and other containers to high, low density polyethylene, polypropylene and polystyrene foam or non-foam sheet, made by thermoforming method for the packaging can reduce the packaging products the cost of. With a variety of high-density polyethylene made of turnover box, easy to clean than the wooden box, disinfection, long service life.

3. Shock-proof packaging materials made of polystyrene, low-density polyethylene, polyurethane and polyvinyl chloride made of foam. Foam foam degree and cross-linking or not, divided into hard and soft two categories; according to the foam structure, split hole and hole two, density 0.02 ~ 0.06g / cm³, for packaging food, medicine, cosmetics And small precision instruments. Polystyrene or low-density polyethylene in the extruder into the pressurized easy gasification of the gas, the extrusion blow molding into a low foam sheet, known as foam paper, in the thermoforming method can be made Food packaging trays, plates, boxes and fast food boxes and other food.
