First Pasteurizeable PET Beer Bottle Due in China.
The three-layer PET barrier bottles are able to withstand the 67 C (153 F) temperatures of tunnel pasteurization for beer. Until now, beer contained in plastic has typically been sterilized in bulk prior to bottling rather than in the bottle after filling. A heat-resistant bottle "means existing pasteurization equipment can be used without any modification," says Paul Swenson, president of Kortec.
The three-layer container has inner and outer skins of PET, with a core layer of a barrier resin--both nylon 6 and EVOH are approved--blended with an an oxygen scavenger. The structure is designed to provide a six-month shelf life.
Kortec is supplying a turnkey preform molding system based on a specially modified 300-ton injection press from Husky Injection Molding Systems Ltd., Bolton, Ont. Kortec itself developed the 48-cavity, hot-runner coinjection mold. Coinjection is used partly because it minimizes delamination during pasteurization.
