The structure and application of PET packaging box-film supplier
The basic material composition of the PET packaging box PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, abrasion resistance, good dimensional stability, low abrasion and high hardness, with the greatest toughness among thermoplastics: good electrical insulation, low temperature influence, but poor corona resistance. Non-toxic, weather resistance, good chemical resistance stability, low water absorption, resistance to weak acids and organic solvents, but not immersed in hot water and alkali. Advantages of PET packaging box 1. It has good mechanical properties, impact strength is 3 to 5 times that of other films, and has good folding resistance; 2. Oil resistance, fat resistance, acrylic acid, dilute alkali resistance, and most solvents; 3. It has excellent resistance to high and low temperatures. It can be used for a long time within a temperature range of 120°C, and can withstand high temperatures of 150°C and low temperatures of -70°C in short-term use, and has little effect on its mechanical properties at high and low temperatures; 4. Gas Low water vapor permeability, excellent gas, water, oil and odor resistance; 5. High transparency, UV blocking, good gloss; 6. Non-toxic, odorless, good hygiene and safety, and can be used directly Food packaging. PET is widely used, mainly for fibers, films and engineering plastics. PET fiber is mainly used in the textile industry. PET film is mainly used for electrical insulation materials, such as capacitors, cable insulation, printed circuit wiring substrates, and electrode slot insulation. Another application area of u200bu200bPET film is film base and base tape, such as movie film, X-ray film, audio tape, electronic computer tape, etc.; PET film also uses vacuum aluminum to make metalized film, such as gold and silver wire, micro capacitor film Wait. The film sheet can be used for all kinds of food, medicine, non-toxic and sterile packaging materials. Glass fiber reinforced PET is suitable for electronic, electrical and automotive industries. It is used in various coil bobbins, transformers, televisions, tape recorder parts and shells, automotive lamp holders, lampshades, incandescent lamp holders, relays, rectifiers, etc. The PET packaging box is a very high-quality choice. There is a great demand for the use of PET packaging boxes in life. Many manufacturers and consumers will use PET packaging boxes during processing and production. There is a high demand for PET packaging boxes in life. The above simply expresses the structure and application of the PET packaging box.
