Films with improved blocking resistance and surface properties

摘要: The invention discloses methods of improving blocking resistant properties and reducing the coefficient friction a multilayer film comprising providing at least one layer an ethylene-propylene impact copolymer having from about 3 % to 30 by weight ethylene, wherein said has no more than two peaks in melting curve within range 110 °C 165 °C, is non-heat sealable, core polypropylene, high density polyethylene (HDPE) or linear low (LLDPE), whereby anti-blocking characteristics improved without necessity adding antiblock slip agent.
