Title:
A packing tube provided with the manufacturing method of the tube-like object for packing tubes, and a tube-like object
Document Type and Number:
Japanese Patent JP6185460
Kind Code:
B2
Abstract:
A method for manufacturing tubular bodies (1) exhibiting an inner circumferential surface and outer circumferential surface (8) for packaging tubes out of a strip-shaped film substrate (2) that encompasses a barrier layer (19) against moisture and/or oxygen, exhibits at least one weldable plastic layer (3), and comprises a beveled first edge face (5) extending in the longitudinal direction of the film substrate (2) and a beveled second edge face (6) spaced apart from the first edge face (5) by the width of the film substrate (2), wherein the first edge face (5) and second edge face (6) are arranged opposite each other with the formation of a tube shape, and welded together during exposure to heat, the first and second edge face (5, 6) are pressed against each other during welding so as to compress the barrier layer (19), accompanied by the formation of a wave geometry encompassing several wave peaks and/or several wave valleys and exhibiting at least three zero crossings and/or at least two equiphase zero crossings.
