POLYOLEFIN FILM WITH ANTI-FOGGING PROPERTY FOR AGRICULTURE

PROBLEM TO BE SOLVED: To provide a polyolefin film for agriculture excellent in low temperature anti-fogging property from an extension initial period even when being preserved in a low temperature and anti-fogging property persistence, and having excellent transparency and no stickiness. SOLUTION: This polyolefin film for agriculture contains based on 100 pts. wt. of a polyolefin resin 0.5-5 pt(s). wt. of an anti-fogging agent as a polyglycerin fatty acid ester. The polyglycerin fatty acid ester satisfies the following three conditions: 1. A constituent polyglycerin comprises ≥20 wt.% of diglycerol and ≥30 wt.% of triglycerol. 2. A constituent fatty acid is composed of C12-22 saturated fatty acid and unsaturated fatty acid. The weight ratio of the saturated fatty acid to the unsaturated fatty acid is (50:50)-(90:10). 3. The esterification ratio of the polyglycerin fatty acid ester compound is 15-65%. Alternatively, the film contains based on 100 pts. wt. of the polyolefin resin the mixture of an additive comprising an ester compound composed of an 8-22C fatty acid and 1-100 mol of ethylene oxide, and the anti-fogging agent. The mixture ratio (wt.% ratio) of the additive to the anti-fogging agent is (5-30):(70-95). COPYRIGHT: (C)2004,JPO
