Abstract

A heat-weldable covering film suitable for use in a blister pack, especially in PTP packs. The heat-weldable covering film comprises a thin card, a filling layer of a polyurethane resin formed on a surface of the thin card, an intermediate layer of a vinyl chloride copolymer modified with acid, and an upper heat-welded covering. The covering film does not give rise to either any resin creep patterns or colour shading in the heat welding operation. <IMAGE>
