How Many Types can Cans and Plastic Bottles be Divided?

Bottled beverages such as mineral water, fruit juice and green tea sold in the market have different degree of hardness and softness.  It is mainly related to the molecular weight of polymers and the arrangement of PET. After all, plastic beverage bottles are linked by many PETs and there is no fixed number. The molecular weight of plastic beverage bottles can range from thousands to millions. Generally speaking, the longer the molecular bond is, the harder the material is. In addition, the neater the PET is arranged, the harder the plastic bottle is. The reason is that it is difficult to bend a number of neatly arranged wires, but if they are arranged in disorder, they will not be so strong.

General plastic beverage bottles generally refer to the plastic with large output, wide use, good moulding and low price. There are five kinds of general plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS). They are all thermoplastic.

Engineering plastic bottle generally refers to the plastic which can withstand certain external force, has good mechanical performance, high and low temperature resistance, good dimensional stability, and can be used as engineering structure, such as polyamide, polysulfone and so on. In engineering plastics, it is divided into general engineering plastics and special engineering plastics. General engineering plastics include: polyamide, polyformaldehyde, polycarbonate, modified polyphenylene ether, thermoplastic polyester, ultra-high molecular weight polyethylene, methyl pentene polymer, vinyl alcohol copolymer, etc. Special engineering plastics can be classified as cross-linked and non-cross-linked. Crosslinking type: polyaminobiamaleamide, polytriazine, crosslinked polyimide, heat-resistant epoxy tree finger, etc. Non-cross-linking: polysulfone, polyether sulfone, polyphenylene sulfide, polyimide, polyether ether ketone (PEEK), etc.

Manufacturer said that generally speaking, special plastics bottle refers to the plastic with special functions, which can be used in aviation, aerospace and other special application fields. For example, fluoroplastics and organic silicon have outstanding functions of high temperature resistance and self-lubrication. Reinforcement plastics and foam plastics have high strength and high cushioning properties. These plastics belong to the category of special plastics.
