The United States developed a successful gas polyester resin PolyShield

PET beer bottles can be divided into single-layer and multi-layer structures. The latest technological breakthrough in the single-layer structure is the newly developed PolyShield Polyester resin with excellent gas barrier properties developed by Invista USA. 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 type of PET blend resin with oxygen absorption and gas barrier properties. Its breakthrough technology is to make single-layer PET beer bottles greatly improve the barrier properties to oxygen and carbon dioxide gas, which is particularly excellent Oxygen absorption avoids the problem of “empty bottle life” for other similar products and meets all beer shelf life standards. PolyShield has obtained the European Union's beer packaging food safety related laws and regulations on July 20th, 2004, and can be directly used for beer packaging. This accreditation includes Germany and other EU countries.
