Abstract
The invention relates to a multi-layer product, in particular for producing containers, comprising a layer formed of a fiber-based packing material on one surface of which a gas-tight multi-layer plastic coating is arranged. To prevent the formation of microholes, the gas-tight multi-layer plastic coating is formed of superposed 1-4 g/m.sup.2 barrier plastic layer, 1-4 g/m.sup.2 binder layer, and surface layer 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.
