Abstract
Abstract A flexible plastics film laminate comprises two layers of thermoplastic film directly joined together face-to-face by a layer of adhesive, wherein each film is metallised on at least one face and at least one of the films consists of polyolefine, the other said film being polyolefine, cellulose or polyamide. The laminate exhibits high gas and moisture barrier properties and is especially useful as a packaging material for oxygen-and/or water vapour-sensitive materials.
