Abstract

A silage film having at least one layer of a resin composition containing an ethylene-vinyl alcohol copolymer (A) and a hydroxy group-containing compound (B). In the resin composition containing the ethylene-vinyl alcohol copolymer (A) and the hydroxy group-containing compound (B), the hydroxy group-containing compound (B) has a molecular weight of less than or equal to 200, a ratio of number of hydroxy groups per molecule to the molecular weight ranging from 0.02 to 0.03, and a melting point of greater than or equal to 23° C., and a content of the hydroxy group-containing compound (B) in the resin composition ranging from 3% to 15% by mass. The silage film has excellent oxygen barrier property and stretchability (suitability for wrapping) and can be suitably used for long-term storage of silage.
