ABSTRACT:
A polymer composition comprising (a) 99 to 75 weight percent of LLDPE and (b) 1 to 25 weight percent of a copolymer of propylene (CP) with 7 to 40 weight % o one or more C.sub.4 to C.sub.12 alpha-olefins and 0 to 10 weight % of ethylene. The propylene copolymer (CP) has a fusion enthalpy not more than 75 J/g. The composition is readily converted into uniform thickness film by extrusion blowing, and exhibits good hot tack strength during heat-sealing operations.
