HEAT-SEALABLE TUBULAR LAMINATE

摘要

The tubular foil laminate has at least a sealable outer print foil (5) of a material based on high-density polyethylene, and an inner polymer support foil (3) which can be sealed with the print foil and whose melting point is the same or a maximum of 20 degrees centigrade less than that of the print foil. Independent claims are included for: (1) a tubular packing shaping body made from a polymer foil laminate whose opposing laminate edges are butt-welded together along the end sides (1a,1b); and (2) manufacturing method for a tube which involves assembling and welding opposite edges of polymer foil laminate to form a tube at a temperature at which the support foil of one edge is welded to the print foil of the opposite edge.
