Structure and Application of PET Packing Box

Basic material composition of PET packaging box

PET is a milky white or light yellow highly crystalline polymer with smooth and shiny surface. It has good creep resistance, fatigue resistance, abrasion resistance and dimensional stability, small wear and high hardness, and has the largest toughness among thermoplastic plastics: good electrical insulation performance, less affected by temperature, but poor corona resistance. It is non-toxic, weather resistant, stable against chemicals, low water absorption, resistant to weak acids and organic solvents, but not resistant to hot water immersion and alkali.

Advantages of PET packaging box

1. It has good mechanical properties, impact strength 3~5 times of other films, and good folding resistance;

2. It is oil resistant, fat resistant, enoic acid resistant, dilute alkali resistant, and most solvents resistant;

3. It has excellent high and low temperature resistance and can be used for a long time within the temperature range of 120 ℃,

Short term use can withstand 150 ℃ high temperature and - 70 ℃ low temperature, and high and low temperature have little impact on its mechanical properties;

4. The permeability of gas and water vapor is low, and it has excellent gas resistance, water, oil and odor performance;

5. High transparency, UV blocking and good gloss;

6. It is non-toxic, tasteless, hygienic and safe, and can be directly used for food packaging.

PET is widely used, mainly for fiber, film and engineering plastics. PET fiber is mainly used in textile industry. PET film is mainly used for electrical insulation materials, such as capacitor, cable insulation, printed circuit wiring substrate, electrode slot insulation, etc. Another application field of PET film is film base and baseband, such as film, X-ray film, audio tape, electronic computer tape, etc; PET film is also made of metallized film by vacuum aluminum, such as gold and silver wire, micro capacitor film, etc. The film sheet can be used for all kinds of food, medicine, non-toxic and sterile packaging materials. Glass fiber reinforced PET is applicable to the electronic, electrical and automotive industries, and is used for various coil frames, transformers, TV sets, recorder parts and shells, car lampholders, lampshades, incandescent lampholders, relays, solar rectifiers, etc.

PET packaging box is a very good choice. There is a large 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 PET packaging box.
