In synthesis, 25% used in packaging industry, therefore an important sector in the plastic packaging, plastic packaging is one of the four materials in the packaging industry
plastics for bag packing
1.Plastics are the main features: first, the density is small, higher than strength, can obtain a higher rate of packed, namely "unit mass packing volume or packing size.
2.most of the plastic good chemical resistance, good acid resistance, alkali resistance, resistance to all kinds of organic rong agent, placed for a long time, without oxidation.
3.Has the good transparency, easy coloring. Fifth, has good strength and unit weight of high strength, impact resistance, easy modification.
4., the processing cost is low. Seventh, insulation.
