    Abstract: PROBLEM TO BE SOLVED: To provide a film having excellent hand-cutting properties, in particular one having good transparency which is suitably applicable to an easy-openable packaging material for foodstuffs, medicines, etc., to provide an adhesive tape having excellent hand-cutting properties, and to provide, in addition, a material which is favorable in sanitation from the aspect of having a fungicidal property, antibacterial activity and the like. SOLUTION: The film is a polylactic acid film wherein haze is ≤20%, a melting point is ≥150°C and the value of breaking strength (MPa)×thickness (μm) is in the range of 100-2,100. A laminate comprising at least two layers consisting of a layer A composed of the polylactic acid film and a sealant layer (layer B), and having 50-700 g tear starting strength, is also provided. The packaging film and the adhesive tape are obtained by using the polylactic acid film. COPYRIGHT: (C)2004,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To prepare a polyester film for lamination which is excellent not only in environmental friendliness but also in embossability and foldability. SOLUTION: In the expansion and contraction curve of the polyester film in the temperature rise under a load of 0.1 Mpa, T1 and T2 of the film satisfy the relation represented by the equation: T2-T1>=8( deg.C), wherein T1( deg.C) is the highest temperature at which the slope of the expansion and contraction curve in the temperature rise changes from a negative value to a positive value; and T2( deg.C) is the temperature at which the expansion in the temperature rise reaches 25%.

    Abstract: PROBLEM TO BE SOLVED: To obtain a polyester film which has a high hiding power, is free of unevenness and excellent in beautifulness and has a high abrasion resistance by incorporating a specified amount (per unit thickness) of titanium oxide containing a specified amount of an inorganic and/or an organic surface-treating agent into the same. SOLUTION: This polyester film contains titanium oxide which has an average particle size of 0.1-0.5 μm and is surface-treated with 0.01-2 wt.% inorganic and/or an organic surface-treating agent. The content of titanium oxide per unit thickness of the film is 1.2-2.5 wt.%/μm. If necessary, the film further contains 0.01-2 wt.%/μm cohesion-type inorganic particles having an average particle size of 0.01-10 μm. Preferably, a layer having a titanium oxide concentration of 2-15 wt.%/μm is formed on at least one side of the film in order to reduce the abrasion of a roll, An aluminum oxide compound or an aluminum hydroxide compound in an amount of 0.01-1.5 wt.%, based on titanium oxide, is preferable as the inorganic surface-treating agent. A silicone compound in an amount of 0.02-2 wt.% or a polyhydric alcohol compound in an amount of 0.01-1.5 wt.%, based on titanium oxide, is preferable as the organic surface- treating agent.
