Huai Ning Mamiao Yousheng Plastic Factory, a professional custom plastic bag manufacturer, introduces the ingredients of plastic bags:
The plastic we usually use is not a pure substance. It is made of many materials. Among them, high molecular polymers are the main components of plastics. In addition, in order to improve the performance of plastics, various auxiliary materials such as fillers, plasticizers, lubricants, stabilizers, colorants, etc. must be added to the polymer to become Good performance plastic.
1. Synthetic resin: Synthetic resin is the main component of plastic, and its content in plastic is generally 40% to 100%. Because the content is large, and the nature of the resin often determines the nature of plastic, people often regard resin as a synonym for plastic. For example, polyvinyl chloride resin and polyvinyl chloride plastic, phenolic resin and phenolic plastic are mixed. In fact, resin and plastic are two different concepts. Resin is an unprocessed virgin polymer that is not only used to make plastics, but also a raw material for coatings, adhesives, and synthetic fibers. In addition to a very small percentage of plastic containing 100% resin, most plastics, in addition to the main component resin, need to add other substances.
2. Fillers: Fillers are also called fillers, which can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood powder to phenolic resin can greatly reduce the cost, making phenolic plastic one of the cheap plastics, and at the same time, it can significantly improve the mechanical strength. Fillers can be divided into two types: organic fillers and inorganic fillers, the former such as wood flour, rags, paper and various fabric fibers, and the latter such as glass fiber, diatomite, asbestos, carbon black and the like.
