发明名称 Packing for single films
摘要 The packing has a smooth, tension-proof, plastic and metallic foil arrangement which surrounds a stack of films in a light-proof and weather-proof manner. Two parallel weld seams weld the foil together at the stack edges and a third weld seam extends vertically thereto. The film stack is embraced somewhat loosely between the welds. The foil extends as a holding strip beyond one of the parallel weld seams and as a substantially longer pull strap beyond the other weld seam. A gusset of the foil arrangement disposed between one weld seam and the film stack has a width allowing the gusset to be cut open and off.
