What material is generally used for clothing packaging bags?


Nowadays, clothing processing factories are generally processing factories, and the clothing packaging of the processing factories generally uses the cheapest packaging bags. The material of this packaging bag is generally HDPE. Then the clothing is shipped to the customer who customizes the clothing, and the customer chooses a better packaging bag according to their needs. At this time, PE plastic bags are generally used, and some customers will use CPE matte bags or PE matte bags for higher requirements. If some customers’ garments are to be exported to developed countries, then fully biodegradable packaging bags must be used. The material of this packaging bag is mainly PLA+PBAT.

Next, let us understand the advantages and disadvantages of various packaging materials:

HDPE is short for high-density polyethylene. In addition to being a white opaque waxy material, it is also a thermoplastic resin. It has the advantages of high crystallinity, non-polarity, heat resistance, cold resistance, stability and rigidity. And it is safe, non-toxic, and odorless.

PE material refers to polyethylene, the English name is polyethylene, so it is referred to as PE. Polyethylene is a thermoplastic resin made by polymerizing ethylene. Polyethylene is odorless, non-toxic, feels like wax, has good chemical stability, has excellent low temperature resistance, and can withstand most acids and alkalis. It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation.

PE matte is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120°C. The electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good, but the corona resistance is poor. Creep resistance, fatigue resistance, friction resistance, and dimensional stability are all very good.

CPE (chlorinated polyethylene material) generally refers to chlorinated polyethylene. It is a saturated polymer material. The appearance is white powder, non-toxic and odorless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. Oil resistance, flame retardancy and coloring properties. Good toughness (flexibility at -30°C), good compatibility with other polymer materials, and high decomposition temperature.

PLA is a new type of bio-based and renewable biodegradable material, made from starch raw materials proposed by renewable plant resources (such as corn, cassava, etc.). Starch raw materials are saccharified to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis.

PBAT is a thermoplastic biodegradable plastic. It is a copolymer of butylene adipate and butylene terephthalate. It has both the characteristics of PBA and PBT. It has both good ductility and elongation at break, as well as Good heat resistance and impact performance; in addition, it also has excellent biodegradability, which is very active in the research of biodegradable plastics and one of the best degradable materials for market applications.
