摘要
The invention relates to a laminated material which comprises a carrier layer of paper or cardboard and an outside layer of extruded polythene applied to one side of the carrier layer. To the other side of the carrier layer is applied a first binder layer of polythene and a layer of aluminum foil placed against the binder layer. A second binder layer of EAA is provided for the bonding together of the aluminum foil with an inner polythene layer which has been produced by blowing and which has a substantially higher modulus of elasticity and strength than the slot-extruded polythene layer. The invention also relates to a method for the manufacture of the laminate by making use of the heat content of the first slot-extruded binder layer of polythene for heating up the second binder layer of EAA to such a temperature that an effective bonding on the aluminum foil is obtained.
