Beschreibung
Zusammenfassung:	The present invention provides a linear low density polyethylene (LLDPE) resin composition for a weathering resistance agriculture film and a preparation method thereof. The resin composition comprises, by weight of LLDPE, (1) 100% of LLDPE, (2) 0.05-0.3% of a compound cross-linking aid, and (3) 10-30% of ultra-low density polyethylene (ULDPE) weathering resistance master batch. With the composition, a broad width shed plastic film (a width of more than or equal to 8 m and a thickness of more than or equal to 80 mum) can be blown out without any blending, fisheyes on the surface of the shed plastic film are less, weathering resistance is excellent, and natural damage can not occur after the shed plastic film continuously covers a greenhouse for more than 40 months. The present invention further provides a preparation method for the resin composition, wherein the preparation method has advantages of short procedure, simple process, low development cost, stable product quality and the like.
