The United States has developed a polyester resin that can produce single-layer PET beer bottles

Recently, the United States Invista has successfully developed PolyShield, a polyester resin with excellent gas barrier properties, which has made breakthroughs in the production technology of PET beer bottles. The technology that would previously require multi-layer composites to produce beer bottles will be replaced, as long as the single layer Make it.

It is reported that the single-layer PET beer bottles produced using this new type of polyester resin can meet the EU beer packaging food safety standards. This new material is a new PET blend resin with oxygen absorption and gas barrier properties, which can significantly improve the barrier properties of single-layer PET beer bottles to oxygen and carbon dioxide gas, and meet all beer shelf life standards. PolyShield has recently been approved by the European Union for beer packaging food safety laws and can be directly used for beer packaging.

PolyShield's single-layer beer bottle technology can use common injection molding machines to produce preforms without significant additional investment and without increasing the complexity of the production process, leading to a significant reduction in product costs. At present, this technology has begun trials in several beer production plants around the world.
