A lidstock film adapted to form a peelable seal with a substrate upon heat sealing comprises, a first layer of high density polyethylene, a second layer of ethylene vinyl acetate, and a third seal layer of a blend of a polyionomer and a low density polyethylene is disclosed. Also disclosed is a forming web adapted to form a peelable seal with a lidstock upon heat sealing, the forming web comprising a first seal layer of a mixture of a rubber and ethylene vinyl acetate, a second layer of a mixture of ethylene vinyl acetate and a linear low density polyethylene, and a third layer comprising linear low density polyethylene. The lidstock film and forming web are heat sealable at temperatures between 250 DEG F. and 350 DEG F. to form packages with peelable seals.
