Patent ID: 8173748

Claim:
A heat-seal resin, comprising: 5 wt % to 95 wt % of a first copolymer and 95 wt % to 5 wt % of a second copolymer based on the total weight of the resin, wherein the first copolymer and the second copolymer together are 90 wt % or more of the total weight of the resin, wherein the first copolymer includes a first monomer of an alphaolefin of 2 to 4 carbon atoms and a second monomer selected from a second monomer of an alphaolefin of 2 to 8 carbon atoms, wherein the first monomer and the second monomer of the first copolymer are different, wherein the first copolymer has an MFR of from 5 to 1000 g/10 minutes and a T fm , of 66° C. to 80° C., wherein the second copolymer includes a first monomer of an alphaolefin of 2 to 4 carbon atoms and a second monomer selected from a second monomer of an alphaolefin of 2 to 8 carbon atoms, wherein the first monomer and the second monomer of the second copolymer are different, wherein the second copolymer has an MFR of from 0.5 to 5 g/10 minutes and a T fm of 45° C. to 66° C., wherein the first copolymer has an MFR of at least 2 g/10 minutes greater and a T fm of at least 10° C. greater than the second copolymer.
