Plastic Packaging The Most Popular Packaging Ways

Plastic classificationPlastic points according to its own performance can be divided into: Can be repeated many times the molten processing forming and basic can keep its characteristics of thermoplasticity and only a molten thermosetting plastic molding two kinds. According to its uses can be devide into widely uses, cheap price, general plastic packaging with better comprehensive properties, such as PE, PP, PVC, PS and amino plastics. Have a good physical and mechanical strength, can instead the metal used in engineering machinery engineering plastics such as: ABS, nylon, polyester, POM, TPX 1, etc. And on a certain performance has a special kind of engineering plastics, such as: has the special good radiation resistance, high temperature resistance and so on the special plastic, such as: aromatic sulfone, liquid crystal polymer, etc. According to the thermoplastic resin molecular crystal size, can put the thermoplastic plastic divided into two categories, the amorphous polymer and crystalline polymer.

Main FeaturesPlastic main features are: First, the density is small, higher than strength, can obtain a higher rate of packed, per unit of the quality of the packing volume or packing size. Second, most of the plastic has good chemical resistance, good acid-proof, alkali resistance, resistance to all kinds of organic solvents, placed for a long time, no oxidization. Third, forming easily, required for forming energy consumption is lower than metal materials such as steel. Fourth, has the good transparency, easy coloring. Fifth, has good strength, the strength of the unit weight of high performance, impact resistance, easy modification. Sixth, the processing cost is low. Seventh, excellent insulation.
Packing containerIn terms of packaging container, original packing beverage container is glass bottle secondly paper composite cans, and then is PET bottle, and now the rigid PET bottle has been the biggest packaging material of carbonated soft drinks and non-carbonated beverages. To be sure, even in the country that plastic packaging industry with the most maligned, plastic will remain at the speed of far more quickly than the other packing materials in period of development, because a lot of characteristics of plastic are irreplaceable by any other kinds of packaging materials. Plastic packaging industry has been in occupation of sales package field at the same time, has been develop to the transport packaging aspect, will eventually compel "transport packaging" still is given priority to with metal, is given priority to with plastic.
