Abstract A laminated material for the manufacture of packing containers with good gas and aroma barrier properties and or parts for such containers, and a method for the manufacture of the laminated material (1). The laminated material (1) comprises a first partial laminate (1) comprising a carrier layer (2) of thermoplastics and a barrier layer (3) of inorganic material of 50-500 Å thickness serving as a gas and aroma barrier and a second partial laminate (1b) comprising a carrier layer (4) and a barrier layer (5) of inorganic material of 50-500 Å thickness serving as a gas and aroma barrier, these partial laminates being joined to one another by means of an intermediate layer (6) of bonding agent, their respective barrier layers facing inwards towards one another.
A laminated material comprising: a first partial laminate comprising a thermoplastic carrier layer and a barrier layer consisting of a silicon compound; a second partial laminate comprising a thermoplastic carrier layer and a barrier layer consisting of a silicon compound; and an intermediate layer of bonding agent joining the first and second partial laminates with their respective barrier layers facing the intermediate layer.
