Single-layer PET technology achieves breakthrough in the UK

With the successful development of a new PolyShield resin with excellent gas barrier properties, the Invista company in the United States has made breakthroughs in PET beer bottle technology. The technology that would previously require multi-layered composites to produce beer bottles will be replaced, as long as single-layer production You can.

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. Poly Shield was approved by the European Union on food safety for beer packaging on July 20, 2004, and can be directly used for beer packaging. This accreditation includes Germany and other EU countries.

The Poly Shield single-layer beer bottle technology can be used to produce preforms using ordinary injection molding machines, which does not require significant additional investment and does not increase the complexity of the production process, resulting in greatly reduced product costs. This technology has been tested at several beer production plants around the world.
