PCT No. PCT/US95/10112 Sec. 371 Date Feb. 5, 1997 Sec. 102(e) Date Feb. 5, 1997 PCT Filed Aug. 9, 1995 PCT Pub. No. WO96/05056 PCT Pub. Date Feb. 22, 1996A seal layer formed from a thermoplastic polymer blend comprising (a) a non-polar, non-ionomeric polyolefin, and (b) a polar ethylene copolymer having carbon monoxide functionality, and its use to adhere adjacent thermoplastic films together to form a package. Since the bonding strength of the thermoplastic films to one another and to the seal layer is greater than the internal cohesion strength of the seal layer itself, the seal layer provides for an easy open package.
