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 ethylene-vinyl polymer to reduce melt fracture, head pressure and to obtain films having excellent anti-blocking characteristics. Optionally, diatomaceous earth is added to further reduce blocking.
