Cover foil designed as push-through foil for a blister package

摘要

A cover foil designed as a push-through foil for a blister package for packing moisture-sensitive products comprises an aluminum foil as a barrier layer against the penetration of water vapor and gases and a sealing layer for sealing against a blister bottom part. A plastic layer containing a moisture-adsorbing desiccant is arranged on the side of the aluminum foil that is equipped with the sealing layer.
