ABSTRACT:
A first web having an ionomer, or ionomer/ethylene vinyl acetate copolymer (EVA) sealant layer, heat sealed to a second web having an EVA/ethytlene butene copolymer (EBC)/polypropylene (PP) sealant layer, forms an easily opened package. A layer adjacent the sealant layer of the second web optionally includes PP or ethylene propylene copolymer. With this optional layer, the sealant layer of the first web may comprise a polymeric material which forms strong interweb adhesion upon heat sealing.
