Patent ID: 8048521

Claim:
A multilayer structure comprising first and second multilayer heat sealant structures, each of the first and second multilayer structures comprising: a coextruded multilayer heat sealant structure comprising a low melt index layer comprising low density polyethylene and a high melt index layer comprising a single site catalyzed polyethylene wherein said single site catalyzed polyethylene has a melt index above about 10 g/10 min for use as a heat sealant layer wherein the high melt index layer is disposed adjacent to the low melt index layer, and further wherein the high melt index layer is coextruded with the low melt index layer and further wherein said low density polyethylene of the low melt index layer has a melt index lower than a melt index of the single site catalyzed polyethylene of the high melt index layer; and wherein at least a portion of the first multilayer heat sealant structure is sealed to at least a portion of the second multilayer heat sealant structure such that the high melt index layers of the first and second multilayer heat sealant structures abut each other.
