ABSTRACT:
A heat sealed, easy-opening and reclosable package, which comprises a packaging material comprised of a heat sealable base member material, and an elongate, multilayer, flexible, peelable and reclosable strip positioned between the surfaces of juxtaposed portions of base member material and comprised of an interior tacky adhesive layer, a first and second surface sealant layers, the strip including a rupturable layer proximate the tacky adhesive layer. The base member material is heat sealed together along and by means of the strip whereat the sealant layers of the strip are heat sealed to the base member. The heat seal has sufficient initial seal strength to remain closed during handling of the package and yet is manually readily openable and reclosable.
The base member material can be heat sealed together by each sealant layer being heat sealed to the same base member heat sealable surface, or by one strip sealant layer being heat sealed to one base member heat sealable surface and the other sealant layer being heat sealed to another heat sealable surface of the base member or of a base structure, which can be a container or a flat base structure.
