1. PE (PE) :
PE is the largest synthetic resin in the world and also the largest plastic packaging material. Polyethylene products are divided into low density, medium density and high density. The high density polyethylene (HDPE) with high crystallinity, the hardness, air tightness and mechanical strength, good chemical resistance are so heavily used blow molding hollow container such as made into bottles. With the characteristics of PE heat sealing, the production of various kinds of composite materials can be made into containers, and can be filled with lemon juice, juice and other beverages.
2. PVC (PVC) :
PVC can be divided into hard products, soft products and paste products. The PVC bottles produced by the injection method are not suture, the wall is thin and uniform, and can be filled with gas drinks such as coke, soda, etc. PVC bottles produced by extrusion blow molding are only suitable for fruit juice and mineral water.
3. PP (polypropylene) :
The development of polypropylene transparent packaging bottle is a hot spot in plastic packaging. With the successful development of the transparent modifier, nucleating agent, adding 0.1% to 0.4% in ordinary PP sorbitol xylene (benzaldehyde) nucleating agent, produced by the high transparent PP bottles can be widely used in thermal sterilization, such as concentrated juice needed hot filling beverage packaging, the price is appropriate, compression resistance to temperature, PS, ABS, PET, PE bottle of new rivals.
4. Polyester (PET or PETP) :
The PET bottle produced by the two-axis extension blow molding method has good transparency, high gloss and glass appearance, which is the most suitable plastic bottle to replace the glass bottle. PET bottle production in recent years, our country has developed rapidly and widely used in all kinds of tea drink, fruit juice and so on need to hot filling beverage, such as Pepsi cola company 600 ml, 1.25 L, 2 L and 2.5 L PET bottle, different volume according to the different needs of individuals, families, praised by the great majority of consumers.
