Abstract

Abstract: PE-LD, m-PELLD,and EVA were compared as agricultural film in their weathering resis- tance.The mechanical properties of m-PE-LLD were better than PE-LD and EVA, however, the haze of EVA was lower than PE-LD and m-PELLD.The aging behavior was tested with tensile property reservation.Theagricultural films made ofm-PELLDand EVA exhibited a higher reservation in elon gation at break but a lower in tensile strength than that of PE-LD.

Key words: agricultural film;polyethylene, molecular weight, molecular weight distribution, anti-aging property
