  Ps lid packaging not only makes goods easy to transport and carry, but also protects and beautifies goods, and plays a role in prolonging the shelf life of goods and promoting sales. With the continuous improvement of living standards, people have higher and higher requirements for the packaging of goods, which leads to the rapid development of the packaging industry. However, packaging not only brings convenience and benefits to people, but also causes serious harm to the living environment of human beings. On the one hand, packaging consumes a lot of resources and energy; on the other hand, the increasing plastic packaging waste has become the fourth largest pollution source of human beings after water pollution, marine lake pollution and air pollution. However, the new generation of Ps lid packaging has many advantages, so Ps lid packaging occupies the dominant position of market packaging.

  Compared with other materials, Ps lid has the following performance characteristics:

  1. Light weight

  Plastic is a light material with a relative density ranging from 0.90 to 2.2. Obviously, because there are micropores inside, the texture is lighter, and the relative density is only 0.01. This characteristic makes plastic can be used in the production of products that require weight reduction.

  2. Excellent chemical stability

  Most plastics have good corrosion resistance to acids, alkalis and other chemicals. Especially polytetrafluoroethylene (F4), commonly known as plastic king, has better chemical stability than gold. F4 is an ideal corrosion-resistant material because of its excellent chemical stability. For example, F4 can be used as the material of pipelines for transporting corrosive and viscous liquids.

  3. Excellent electrical insulation performance

  Ordinary plastics are poor electrical conductors, and their surface resistance and volume resistance are very large, which can reach 109-1018 ohms in digital terms. The breakdown voltage is high and the tangent value of dielectric loss angle is very small. Therefore, plastics are widely used in electronic industry and mechanical industry. Such as plastic insulated control cables.

  Ps lid, with its excellent performance, has brought great influence to modern civilization, and has developed rapidly. It has penetrated into various fields of industry, agriculture, national defense and daily life, and brought great convenience to people's lives.
