What is packing material?
Packaging materials refer to the materials used for manufacturing packaging containers, packaging and decoration, packaging and printing, packaging and transportation to meet the product packaging requirements. They include metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fiber, chemical fiber, composite materials and other major packaging materials, as well as coating, adhesive, strapping, decoration, printing materials and other auxiliary materials Supporting materials.
Today, Aokai plastic mainly introduces two kinds of plastic packaging materials. One is PVC, the other is pet.
Application of PVC packaging materials
PVC is mainly composed of PVC. In addition, other ingredients are added to enhance its heat resistance, toughness, ductility, etc. It is one of the most popular and widely used synthetic materials in the world. It is the second most widely used synthetic material in the world.
At present, PVC packaging industry is developing rapidly in the world, with a broad prospect. All countries are optimistic about the potential of PVC and its benefits to the ecological environment. PVC is proving its role and position to the world with its superior and unique performance. It is irreplaceable by any other product at present. Social development needs it, and environmental protection needs it. It is the inevitable trend of our social civilization and progress.
Application of PET packaging materials
Pet is a milky white or light yellow, highly crystalline polymer with smooth and glossy surface. As a packaging material, pet has the following advantages:
1. It has good mechanical properties, impact strength is 3 ~ 5 times that of other films, and good bending resistance.
2. Resistant to oil, fat, enoic acid, alkali and most solvents.
3. It has excellent high and low temperature resistance.
4. The permeability of gas and water vapor is low, and it has excellent properties of gas resistance, water, oil and peculiar smell.
5. High transparency, UV blocking, good gloss.
6. It is nontoxic, tasteless, hygienic and safe, and can be directly used in food packaging.
PVC and pet have their own advantages in packaging materials, so we need to choose suitable packaging materials according to your needs. For the application of PVC and PET packaging materials, plastic packaging materials will continue to grow steadily, still full of vitality in the field of packaging materials, and will continue to play a positive role in protecting goods and improving the value of goods.
