Multi-layer product

The invention relates to a multi-layer product, in particular for producing containers, comprising a layer (1) formed of a fiber-based packing material on one surface of which a gas-tight multi-layer plastic coating (3) is arranged. To prevent the formation of microholes, the gas-tight multi-layer p...

More Information
Summary:The invention relates to a multi-layer product, in particular for producing containers, comprising a layer (1) formed of a fiber-based packing material on one surface of which a gas-tight multi-layer plastic coating (3) is arranged. To prevent the formation of microholes, the gas-tight multi-layer plastic coating (3) is formed of superposed 1-4 g/m barrier plastic layer (4a,4b,4c,4d,4e), 1-4 g/m binder layer (5), and surface layer (6) of a heat-sealable polyolefin material having sufficient thickness for liquid-tight heat sealing, so that the barrier plastic layer is the closest of said layers to the fiber-based packing material layer (1).
