Abstract

A layered material such as a packaging laminate for a packaging container possessing superior oxygen gas and aroma barrier properties is disclosed. The packaging laminate comprises a first laminate unit (10a) and a second laminate unit (10b) which are bonded together by the intermediary of an interjacent layer of an adhesive (11). The first laminate unit has a rigid, but foldable core layer (12) and outer, surrounding layers (13; 14) of thermoplastic, and the second laminate unit has a flexible substrate or carrier lays (15) of thermoplastic which, on its surface, carries a layer (16) acting as an oxygen gas and aroma barrier and consisting of a silicon oxide deposited by chemical plasma deposition and having the general chemical formula SiO x, in which x may vary within the range of between 1.5 and 2.2. A flexible laminate having an SiO x barrier layer is also disclosed.
