ABSTRACT:
The extrudability of linear polymers of ethylene such as low density copolymers of ethylene and C.sub.4 -C.sub.10 olefins (LLDPE) into thin films is improved by adding small amounts, e.g., 0.02 to 2 weight percent polyvinylidene fluoride to reduce melt fracture, head pressure and to obtain films having excellent anti-blocking characteristics.
