Zusammenfassung:Anti-blocking polymer compositions comprise at least one ethylene/a-olefÊninterpolymer and at least one anti-blocking agent comprising an amide. The ethylene/a-olefÊn interpolymers are a multi-block copolymer comprising at least one soft block and at least one hard block. The anti-blocking agent can be erucamide or other amides. The anti blocking polymer composition has a pellet blocking strength of equal to or less than (100) lbs/ft2 (4800 Pa). When the anti-blocking polymer composition is made into a film, the film has a blocking force of less than about (100) grams, measured according to ASTM method (D-3354).
