ABSTRACT:
Packaging laminate with excellent sealing and barrier properties comprising a skeletal layer (11) of plastic and filler mixed in the plastic and a barrier layer (12) of plastic of the same type as the plastic in the skeletal layer in a mixture with plastic of another type than the plastic in the skeletal layer, placed against one side of the skeletal layer.
In order to improve the sealing properties of the packaging laminate the barrier layer (12) has been provided with electrically conducting material finely distributed in the barrier layer, preferably soot (carbon black) with the aid of which the packaging laminate can be sealed by means of inductive heating (IH) and dielectric sealing.
