发明名称 LAMINATED FILM AND AGRICULTURAL SHEET
摘要 PROBLEM TO BE SOLVED: To provide a laminated film adapted to use for an agricultural sheet, building surface-coated film or glass scatter-preventive film with excellent weatherability, tear resistance, executability and transparency. SOLUTION: This laminated film is obtained by laminating three or more layers in a thickness direction. The film comprises a layer containing polyester as a main component, and a layer containing 2,2-bis(4'-β-hydroxyalkoxyphenyl) propane copolymerized polyester as a main component. In this case, a ratio (La/Lb) of an elongation La of the laminated film after 60 hours of a weather test to an elongation Lb of the film before the weatherability test is 0.7 or more.
