1. What is PET material？ PET is a polymer material, the full name is polyethylene terephthalate, which is synthesized by transesterification of dimethyl terephthalate and ethylene glycol or esterification of terephthalic acid and ethylene glycol, and then the condensation reaction. This material is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface....

1. Introduction of the material:  PVC is polymerized from vinyl chloride monomer and is one of the commonly used thermoplastics. Its trade name is referred to as "Chloroplastic".  Pure polyvinyl chloride resin is a hard thermoplastic material, its decomposition temperature is very close to the plasticization temperature, and its mechanical strength is poor. Therefore, it is impossib...

1. What is PP material?  pp stands for polypropylene material in plastics. Polypropylene is a thermoplastic resin obtained by polymerizing propylene. The copolymer-type PP material has lower heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but has stronger impact strength. The impact strength of PP increases with the increase of ethylene content.  ...

1. What is the product made of : PS (polystyrene plastic) refers to a class of plastics including styrene groups in the macromolecular chain, including styrene and its copolymers. Its characteristics are colorless, odorless and tasteless. PS is a relatively old plastic. After many years, its production process is relatively perfect. PS has good transparency (light transmittance of 88%-92...

1. Introduction of CPET: CPET is a polyethylene terephthalate material, which is odorless, tasteless, colorless and non-toxic. It is recognized as the best food packaging material in the world today.  Products made of CPET material can be processed directly in the oven for various foods. It will not release any harmful substances and gases during the heating process, which is called gree...

Commonly used sheet materials include PVC, PET, PP, PS and flocking sheets, gold-plated sheets and anti-static sheets based on these plastic. 1. Polyviny Chloride(PVC) : PVC is the most commonly used plastic material, its texture is very soft, strong toughness, and good plasticity. This material can be made into transparent and various colors, and is often used in various electronics, cosmetics, t...

The Lifecycle of a Cornstarch Container We briefly touched upon the lifecycle of cornstarch packaging in our previous section, but it is worth going into more detail about why this material is so much better than traditional plastics. For starters, at the beginning of this package’s lifecycle, it is derived from renewable resources, unlike petroleum-based plastic. And in the processing and manufac...
