The characteristics of plastic handbags are:
First, the density is small and the specific strength is high, which can obtain a higher packaging yield, that is, "the packaging volume per unit mass or the size of the packaging area, which is the physical advantage of plastic packaging.
Second, most plastics have good chemical resistance, excellent acid resistance, alkali resistance, and resistance to various types of organic balsamic agents. Long-term storage will not cause oxidation. This is the chemical advantage of plastic packaging.
Third, the molding is easy, and the energy consumption for molding is lower than that of metal materials such as steel. This is the low-carbon advantage of plastic bags.
Fourth, it has excellent transparency and easy coloring. Plastic bags are beautiful and elegant.
Fifth, it has outstanding strength, high strength function per unit component, impact resistance and easy modification.
Sixth, the processing cost is low. This is an easy-to-process advantage of plastic packaging. Seventh, excellent insulation.
