Easy open package

Claim 1

An easy open package adapted to be heat sealed to a closed condition to contain and protect product disposed therein, but which is readily openable by application of force, said package including a first package wall having a first thermoplastic polymeric film construction comprising a first outer layer, a first inner sealant layer of polymer and a first tie layer disposed between said first outer layer and said first inner sealant layer, said tie layer comprising a combination of polybutylene and one other constituent and being peelably bonded to one of either said first outer layer or said first inner sealant layer and being permanently bonded to the outer layer to which said tie layer is not peelably bonded, a second package wall joined at a portion of its perimeter to said first package wall, said second package wall having a second thermoplastic polymeric film construction with a second inner sealant layer of the same polymer as, and disposed adjacent to, said first inner sealant layer of said first film construction, whereby when said first inner sealant layer of said first film construction is heat sealed to said adjacent second inner sealant layer of said second film construction along a heat seal, a bond is formed between said inner sealant layers having greater bond strength than the peelable bond between said tie layer and said one layer of said first film construction to which said tie layer is peelably bonded such that upon application of force to open said package, the first and second inner sealant layers will remain bonded together and opening will take place between the peelably bonded layers at said heat seal.
