Heat-sealable tubular laminate

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 connecte...

Beschreibung
Zusammenfassung:	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° 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.
