Abstract: PURPOSE:To obtain a polymer-coated metal laminate adapted for a metal can in which impact resistance and taste characteristics are excellently compatible by coating a polyester layer having a specific melting point obtained by mixing ethylene glycol, butanediol residue, telephthalic acid residue and isophthalic acid residue at specific molar ratio by extrusion laminating. CONSTITUTION:A layer formed of polyester having a melting point of 120-265 deg.C obtained by mixing ethylene glycol residue and butanediol residue at a molar ratio of 20:80-95:5 and terephthalic acid residue and isophthalic acid residue at a molar ratio of 50:50-100:0 is covered by extrusion laminating. That is, in order to extrusion laminate the polyester having a specific melting point in which the ethylene glycol and butanediol are introduced on metal, in the case of molding to manufacture a can, excellent impact resistance is obtained even via many heat history such as heat treatment in the can forming step and retorting after the can forming.

Abstract: PURPOSE:To enable shock resistance of a coated metal which is formed to be extremely improved by a method wherein when one side surface of a metal sheet is coated with a polyester film, ultrasonic vibration air is blown against the surface of the film at coating time or at least just before coating. CONSTITUTION:When a metal sheet is coated with a polyester film, ultrasonic vibrating air is blown against the surface of the film in coating or at least just before coating. In a carboxylic acid component of polyester, terephthalic acid, and isophthalic acid are preferable from standpoints of shock resistance and a taste characteristic. In a glycol component, ethylene glycol is preferable from stand-points of shock resistance and the taste characteristic. Herein ultrasonic air is blown against a surface of the polyester film at least just before coating, and the ultrasonic wave is so set as to have many peaks within a range of 20-60kHz. By this blowing, a coated polyester in a baking treatment after squeezing and drawing a coated metal and after retort treatment is made difficult to generate fissure, pinhole, breaking, crack, etc., and indicates excellent performance as the metal coating.

Abstract: PURPOSE:To make a biaxially oriented film having a specified Young's modulus and thrust strength applicable appropriately to agricultural houses and tents by improving such properties as weathering, workability, durability, and impact resistance by incorporating a given amount of an ultraviolet absorbent. CONSTITUTION:A biaxially oriented film of flexible polyester from polyethylene terephthalate as a main component is obtained which has a Young's modulus of 10-250kg/mm and thrust strength of 10kg/mm or more. This flexible polyester film is incorporated with 5wt.% or less of an ultraviolet absorbent, which gives the film weatherbility and flexibility. The flexible polyester preferably contains 1-40mol% of a long-chained aliphatic dicarboxylic acid having 10 or more C alkylene group, e.g. dimer acid, as a monomer component. Moreover, a polyester layer having a glass transition point of 45 deg.C or higher is preferably laminated on one side of the flexible polyester film.
