Profiled plastics bag closure strip and adhesive bonding method |
摘要 |
A closure strip (1) which incorporates a profiled closure element for use in resealable or reclosable bags is provided with a channel (4) in its surface which contacts a bag forming substrate material (6) for receiving adhesive (5). The presence of the channel ensures that a suitable thickness of adhesive is present at the time of bonding of the closure strip to the substrate. The invention also provides a method of making bag forming material by use of such a closure strip.
