Abstract:
A package comprising:a first package wall having a multilayer film construction, said multilayer film construction comprising:a first, external layer; a second, tie layer comprising a blend of about 65% to 90% by weight an anhydride modified polyethylene and about 10% to 35% by weight of a compound selected from the group consisting of polybutylene, polypropylene and a styrene-butadiene copolymer such that a peelable bond is formed between said first, external layer and said second, tie layer; a third, core layer comprising ethylene vinyl alcohol; a fourth, tie layer comprising an anhydride modified polyethylene and a fifth, external layer; anda second package wall joined at a portion of its perimeter to said first package wall; wherein said first, external layer of said first package wall is heat sealed to said second package wall to create a sealed package such that a bond is formed between said first, external layer of said first package wall and said second package wall having a greater bond strength than said peelable bond such that upon application of digital pull-apart force said first and second package walls will remain bonded together and delamination will occur at said peelable bond between said first, external layer and said second, tie layer of said first package wall wherein said package is opened by the use of digital force.
