REUSABLE CLOSURE SYSTEM FOR PACKAGING

摘要

A reusable closure system is disclosed for flexible packaging applications. The system generally includes base and lid portions. The base portion (109) can be bonded to underlying package material and includes first and second fields of touch fasteners (111) separated by a multi-layer buffer zone (113). The buffer zone can be at least in part co-located with a frangible region of underlying package material. In some embodiments, the buffer zone is substantially free of active bonding agent, such that there is little or no active bonding agent overlapping the frangible region. One of the touch fastener fields of the base can be deployed at least partially within the area defined by the frangible region (102). The other touch fastener field is deployed around the buffer zone. The lid portion can be bonded to the package material and/or base portion, and includes a hinge and another touch fastener field to mate with the base fields.
