发明名称 RECLOSABLE PACKAGING SEAL AND METHODS RELATING THERETO
摘要 The present invention is directed to a releasable bond between two or more overlapping multi-layer film surfaces comprising a plurality of closely spaced, interconnecting indentations. More specifically, the releasable seal of the present invention is directed to the simultaneous embossing of precisely configured identations, involving multi-layer films which can heat seal together during the embossing operation; the resulting seal layer is designed and configured to delaminate and tear when the package is initially opened, while the indentations are designed and configured to re-engage and partially re-seal when the package is later closed.
