<p>PROBLEM TO BE SOLVED: To provide a multilayer film for use in farming, excellent in the effect for inhibiting UV rays in a wide wavelength range, the long lasting effect for inhibiting UV rays, and the long lasting weatherability.SOLUTION: A multilayer film 1 for use in farming includes an A-layer 2, a B-layer 3, and a C-layer 4 which are laminated in the order mentioned. The A-layer 2 includes a polyolefin resin, a triazine-based UV ray absorber, and a hindered amine-based light stabilizer including an organic group or an organic functional group bonded directly to, or through an oxygen atom to the nitrogen atom of a piperidine ring. The B-layer 3 includes a single or a plurality of layers including a polyolefin resin, and at least one of the layers includes benzotriazole-based UV absorber. The C-layer 4 includes a polyolefin resin. The multilayer film 1 for use in farming includes 0.05 to 0.5 parts by mass of the triazine-based UV ray absorber, 0.1 to 1.0 parts by mass of the benzotriazole-based UV ray absorber, and 0.1 to 1.0 parts by mass of the hindered amine-based light stabilizer, relative to 100 parts by mass of the polyolefin resin.</p> |
