Title:
AGRICULTURAL FILM
Document Type and Number:
Japanese Patent JP3235897
Kind Code:
B2
Abstract:
PURPOSE: To obtain an agricultural film excellent in heat insulating properties and durability by arranging a layer composed of a hydrophobic resin to both surfaces of a layer based on an ethylene/vinyl alcohol copolymer resin.
CONSTITUTION: An agricultural film is composed of a laminated film constituted by laminating a layer composed of a hydrophobic resin on both surfaces of a layer composed of a resin compsn. prepared by adding 5-100 pts.wt. of a copolymer selected from a polyamide/polyether copolymer, a polyester/polyether copolymer and a polyamide/polyester/polyether copolymer to 100 pts.wt. of EVOH. EVOH to be used contains 20-70mol%, pref., 25-65mol% of ethylene and has a saponification degree of 80% or more, pref., 95mol% or more.
