Packaging with cycloolefin food/beverage contact layer

Packaging with cycloolefin food/beverage contact layer

A method of food packaging employs a flavor-preserving food contact layer of cycloolefin copolymer characterized by a total extractable concentration of less than about 30 ng per cm2 of surface area when incubated in a 40 ml solution of 10% ethanol in distilled water for 24 hours at 60° C. with cons...

Zusammenfassung:A method of food packaging employs a flavor-preserving food contact layer of cycloolefin copolymer characterized by a total extractable concentration of less than about 30 ng per cm2 of surface area when incubated in a 40 ml solution of 10% ethanol in distilled water for 24 hours at 60° C. with constant agitation. The food contact layer preferably exhibits a flavor scalping value lower than polyethylene.
