Abstract
The invention relates to a polymer film laminate (1), which can be heat-sealed to form tubular packaging, in particular a tube and which comprises at least one self-sealing outer printed film (5) consisting of an HDPE-based material and an inner polymer self-sealing support film (3) that is connected to the printed film (5) and whose melting point is identical to or a maximum 200.degree. C. less than that of the printed film (5). The edges of the tube can abut or overlap to form the tube seam. If the seam edges abut and form a height misalignment (h) between opposing seam edges (1a, 1b), the support film (3) of one edge bonds to the printed film (5) of the opposing edge, maintaining a highly stable seam even under said conditions.
