The main characteristics of plastic packaging are:
First, the density is small, the specific strength is high, and a higher packaging yield can be obtained, that is, the “package volume or packaging area per unit mass.”
Second, most plastics have good chemical resistance, good acid resistance, alkali resistance, resistance to various organic solvents, and long-term storage without oxidation.
Third, the molding is easy, and the required molding energy consumption is lower than that of metal materials such as steel.
Fourth, it has good transparency and easy coloring.
Fifth, it has good strength, high strength per unit weight, impact resistance, and easy modification.
Sixth, the processing cost is low.
Seventh, excellent insulation.
