Document Type and Number:
Japanese Patent JP3148463
Kind Code:
B2
Abstract:
PURPOSE: To obtain an agricultural film having excellent transparency, heat insulation, dust adhesion preventiveness, non-dripping properties, film strength, etc., and excellent safety to an environment at the time of incinerating.
CONSTITUTION: An agricultural film is obtained by laminating ethylene-vinyl acetate copolymer saponified material having an ethylene content of 20-50mol%, saponification value of 90mol% or more, a melting point (Tm) of satisfying a formula of Tm<220-1.46Et+3.31 (Sv-99.6) and preferably a formula of 120-1.46Et+3.31 (Sv-99.6)<Tm<220-1.46Et+3.31 (Sv-99.6) at least on one side surface of a polyolefin resin film, wherein Tm is a melting point (°C) by measurement of a differential scanning type calorimeter, Et is ethylene content (mol%), and Sv is a saponification value (mol%).
