ABSTRACT:
The present invention is directed to a resealable 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 indentations, involving multilayer 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.
