ABSTRACT:
Packaging laminate for conversion through fold forming and sealing to a packaging container with good gas and aroma barrier properties. The packaging laminate has a skeletal layer and a gas and an aroma barrier layer, placed on one side of the skeletal layer, of an organo-functional siloxane polymer which, by means of co-valent bindings, is bound to the skeletal layer by a layer of polyolefine placed between the skeletal layer and the gas and aroma barrier layer.
The packaging laminate can be manufactured through coating one side of a strip of a polyolefine coated paper or cardboard or of polyolefine with a layer of an organo-functional siloxane polymer solution, then drying the layer and finally hardening the dried layer through electron radiation in order to bind the layer co-valently to the strip.
