金属化フィルム
Document Type and Number:
Japanese Patent JP2010521340
Kind Code:
A
Abstract:
Provided herein are multilayer film structures that may be used in packaging applications, for example. The multilayer film structures include a first metallized thermoplastic film and a second thermoplastic film. These first and second films are joined directly to each other over at least a portion of their surface area to form a laminate having the structure "first thermoplastic film/metallic layer/second thermoplastic film". The thermoplastic layers of the films may be the same or different and comprise one or more ethylene acid copolymers or ionomers thereof. The first metallized thermoplastic film has an optical density of 3 or less. When the first metallized thermoplastic film and the second thermoplastic film are joined by heat sealing to form the structure "thermoplastic film/metallic layer/thermoplastic film", its internal seal strength is at least about 4 N/15 mm.
