发明名称 Bending line along overlapping layers in folding box
摘要 In a folding box consisting of a cardboard blank part (1) and a plastic foil blank part (3) glued thereto, thinned-down areas (17) are placed in the foil blank part (3) at the overlap spots between the two blank parts in the area of the box edges, which directly adjoin the bend lines (13) and extend at least across the overlap length. The thinned-down areas (17) compensate stresses arising in the foil material at the overlap spots during folding, this compensation being by deformation, without which the cardboard material is stretched at the edge overlap spots so that it tears.
