What is the place of plastic food bottles in life
We often use plastic bottles to contain food in our lives. Plastic bottles have the advantages of being lightweight, unbreakable, easy to carry and widely used, so they have a strong applicability in our lives. As a result, its place in our lives is becoming more and more prominent. But how many of us know much about the plastic bottles we use? Most people just use plastic bottles, but don't really know much about them. What are plastic bottles made of? What works? How do they work? How long will they last? What should I do after using them? These questions are often overlooked. Let's talk more about the classification of plastic food bottles and the precautions to be taken in their use.
　　1. Plastic bottles for general food use. This plastic bottle is a second-class plastic bottle, usually used for packaging drinks. In summer, we often drink drinks, but at this time of the year, the bottles we get can feel a certain thickness. This kind of drink is not harmful to our health, but it should not be reused for a long time.
　　2. Mineral water bottles belong to the third class of plastic bottles, which are very thin in texture and will be greatly deformed when squeezed by hand. Such plastic bottles are useless and will deform especially when they encounter hot water. The use of such plastic bottles can only be used once in science, and should be thrown away directly after use. If used repeatedly for a long time, it is not good for our health.
　　3. It can be used to heat plastic bottles. There is now a plastic bottle that can be heated, which is much better than ordinary plastic bottles. However, it is not recommended for long-term use. After all, plastic bottles have various additives added during the production process. If used for a long time, they will definitely damage our health.
　　As the manufacturing technology of food plastic bottles is constantly updated and the variety is enriched, there will be more new plastic bottles on the market in the future to satisfy people's lives.

Talk about how to improve plastic bottles without gloss
Firstly, to improve the surface gloss of plastic bottles, called brightening; secondly, to reduce the surface gloss of plastic bottles, also known as matting. Brightening of plastic bottles is to improve the surface gloss or smoothness of plastic bottles. In addition to the reasonable choice of raw materials, specific methods include adding brightening method, blending brightening method, shape control brightening method, molding preparation flatness control, secondary processing brightening method and surface coating brightening method.
　　The choice of plastic raw materials is a fundamental factor in improving the surface finish of plastic bottles. If the raw material is well selected, it is easy to improve the gloss. On the contrary, it is more difficult.
　　Many plastic bottle manufacturers believe that melamine resin, ABS, PP and other resins are better gloss: emulsion-type PVC resin than suspension-type PVC resin gloss; different polymerization methods synthesized varieties of gloss, corresponding to the greater the gloss of the product, the wider the molecular weight distribution, corresponding to the lower the gloss of the product. This is mainly because of the wider molecular weight distribution and the increased irregularity of the material.
