Abstract
A package is provided that is formed from a packaging material, such as film, having increased adhesive in critical locations, such as adjacent folds in the end seal and other areas so that that the increased adhesive can at least partially fill voids adjacent such folds. The additional, localized sealant material is applied in a plurality of discrete locations in the end seal or other region adjacent where folds are formed and overlap with a sealant layer so as to provide additional sealant material for at least partially filling the voids without being present throughout the entirety, majority or large portions of the packaging material.
Claims8
A package formed from a packaging material having at least a base layer and a sealant layer, the material having discrete and spaced apart deposits of adhesive disposed on the sealant layer in a plurality of discrete locations, wherein the sealant layer is a heat sealant layer or a cold sealant layer and made of a first material and the deposits of adhesive are made of a second material having both a lower melting point and a higher caulkability than the first material and comprising at least one of polyethylene, EVA, ionomer metallocene LLDPE, metallocene vLDPE, LDPE, VLDPE, LLDPE, acid copolymer, terpolymer, amorphous copolymer, PB-1, TPE, starch-containing polymer, and PBS, the package having one or more end seal regions having folds, with the discrete and spaced apart deposits of the adhesive being positioned adjacent to the folds such that the discrete and spaced apart deposits of the adhesive at least partially fill voids adjacent the folds.
