Title:
BAG-PRODUCING MACHINE, BAG-PRODUCING METHOD, AND BAG
Document Type and Number:
WIPO Patent Application WO/2022/264652
Kind Code:
A1
Abstract:
This bag-producing machine and bag-producing method successively produce a bag openable by release of a releasable portion using at least two web-shaped barrel parts. The bag-producing machine includes a coating device and a heat seal device. The coating device coats a release agent for heat seal inhibition in a surface region corresponding to a releasable portion of at least one of the two barrel parts in a pattern shape. The heat seal device heats and presses the two barrel parts over the above surface region, and heat-seals the barrel parts to each other at a place at which the release agent is not interposed between the two barrel parts.
