Recently, the United States Invista successfully developed a PolyShield resin with excellent gas barrier properties, which has made breakthroughs in the production technology of Pet Resin beer bottles. The technology that would previously require multi-layered composites to produce beer bottles will be replaced. Monolayer production can be.
Industry insiders analyzed that single-layer Pet Bottle Resin produced using this new type of polyester resin can meet the EU food safety standards for beer packaging. This material is a new kind of PET blend resin with strong oxygen-absorbing and gas-barrier properties. It significantly improves the barrier properties of single-layer PET beer bottles to oxygen and carbon dioxide gas, and meets all beer shelf-life standards. PolyShield has recently been approved by the Rubber And Plastic European Union for beer packaging food safety laws and can be directly used for beer packaging.
An ordinary injection molding machine can produce PolyShield single-layer beer bottle preforms, downstream manufacturers do not need significant additional investment and will not increase Boric Acid Flakes the complexity of the production process. Multi-layer conversion to a single layer, which greatly reduces the cost of the product. At present, this Melamine Powder technology has already begun trials in several beer production plants around the world and is expected to produce good economic benefits.
