Abstract
A packaging material suitable for forming a heat sealable, easy-opening and reclosable package is comprised of a heat sealable base member material having a first heat sealable surface and, secured to the heat sealable surface, an elongate, heat sealable, multilayer, flexible, peelable and reclosable, preferably coextruded, strip comprised of an interior tacky adhesive layer, first and second sealant layers each comprised of heat sealable polymer, and a rupturable layer, preferably comprised of an ionomer, proximate the tacky adhesive layer. One of the strip sealant layers is secured to the first heat sealable surface of the base member. The strip enables the base member to be heat sealed along and by means of the strip to form a package whose heat seal has sufficient initial seal strength to remain closed during handling and yet can be manually readily opened and reclosed.
