Pet Bottle Preform Bring Together Various Advantages

Pet Bottle Preform bring together the advantages of plastic bottles of various materials. As far as plastic containers are concerned, the earliest widely used materials are PE and PVC. For the purpose of environmental protection, improvement of barrier properties and cost reduction, the materials used now mainly include PE and PVC. , PP, PET, etc. PE is the world's largest synthetic resin and the most expensive plastic packaging material, but the lower rigidity of PE plastic bottles has certain limitations in the application of plastic bottle packaging. PET is widely used in blow molding to make hollow containers such as bottles, which can hold drinks such as lemon juice and juice. The PET bottle seamless line produced by the injection-blow method has a uniform thickness and can hold carbonated beverages; the PET bottle produced by extrusion blow molding is suitable for holding juice and mineral water. Due to the wide use of hot filling technology in various tea beverage and juice beverage canning production lines, BOPP hot-filled beverage bottles with high temperature resistance of 100 °C are excellent in high temperature resistance and cheaper than PET bottles. The price makes it a certain market, but its barrier property is worse than PET, and it is also unusable for packaging with high barrier requirements. PET bottles have developed rapidly in competition with other packaging materials (glass, PP, PE, PVC, etc.) due to their superior performance, low cost and adaptability to environmental protection. PET bottles have the proper rigidity, high strength, beautiful appearance, flexible design, and good transparency. It is the most suitable plastic bottle to replace glass bottles. However, the inherent defects of plastic materials have limited the development and application of PET bottles. For example, PET has a low glass transition temperature, shrinkage and cracking during hot filling, poor gas barrier properties for oxygen and carbon dioxide, and corrosion of polar solvents.      Jilian Plastic Mould is a pet product design and manufacturer with relatively influential and well-known in the market.
