What are the raw materials made of glass and plastics?
Low density polyethylene, referred to as LDPE is the amount of varieties of plastic packaging and printing industry in most countries. The proportion is 0.92 ~ 0.93, can float in water. Low crystallinity (60%), under the pressure of 1000 ~ 3000kg/C square meters of bulk polymerization of high pressure polyethylene. At 23 degrees Celsius, the density of rolling around 0.92. The molding is poor, for blow molding processing into tubular film. It is suitable for food packaging, packaging, cosmetics packaging fiber products.
PVC PVC formula (CH - CH) n, is one of the most important types of vinyl polymers, is currently the world's second largest after the polyethylene plastic varieties. In domestic production in the plastic is in the first place. In the printing industry, often with PVC color rolled thin film and transparent glazing film making books, folders, tickets and other packaging decoration cover.
Polyethylene (Polyethylene, PE), referred to as PE. is ethylene organic polymer compound. Polyethylene is the best material in contact with food. Non-toxic, tasteless and odorless, conform to the hygiene standards of food packaging. Polyethylene film, transparent, with moisture, oxygen, anti acid and alkali resistance, air tightness in general, excellent heat sealing properties. Known as "plastic flowers" reputation. Plastic packaging and printing volume is the largest and most important materials.PVC-- PVC
