    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 superior fitness to the case, a superior insulation and a heat resistance by setting the thermal shrinkage ratio of a film in hot air at a specified temp. to a specified value or higher at least in one direction and a specified value or less in a perpendicular direction thereto. SOLUTION: This thermally shrinkable polyester film for capacitor cases has such a shrinkage property that the thermal shrinkage ratio of the film in hot air at 100 deg.C is 30% or more at least in one direction and 20% or less in a perpendicular direction thereto. It prefers to add grains of a mean grain size of 0.005-5 μm by 0.01-3 wt.% in polyester at a printing point, the surface wet tension on at least one surface of the film is preferably 45 mN/m or more at a point to make the printing property better, and the glass transition point of the polyester film is pref. 60 deg.C or more.

    Abstract: PROBLEM TO BE SOLVED: To obtain a surface-protection film having moderate initial tackiness even to an adherend such as a synthetic resin plate having surface roughness, stably keeping the tacky adhesive force at high temperature and after aging and easily peelable without leaving residual adhesive on the adherend. SOLUTION: A tacky adhesive layer is formed on one surface of a substrate film composed of a polyolefin resin. The tacky adhesive layer is composed of a resin composition produced by compounding 5-100 pts.wt. of a tackifier resin to 100 pts.wt. of a hydrogenated resin of a styrene-based random copolymer composed of 7-45wt.% of a styrenic monomer and 93-55wt.% of butadiene.

    Abstract: PURPOSE:To enhans gas barrier properties and moisture proofness to a large extent by a resin layer based on a syndiotactic polypropylene polymer, an isotactic polypropylene polymer or a mixed resin of them to the single surface of a base layer based on an isotatic polypropylene copolymer. CONSTITUTION:A non-stretched polypropylene composite film for metal vapor deposition is obtained by laminating a resin layer (B-layer) based on a syndiotactic polypropylene polymer (sPP), an isotactic polypropylene polymer (iPP) or a mixed resin of sPP and iPP to at least the single surface of a base layer (A-layer) based on an isotactic polypropylene copolymer (iCPP). The mixing ratio of iPP and sPP of the B-layer is 9:1-1:9. When the m.p. of the resin constituting the B-layer is higher than that of iCPP constituting the A-layer by 5 deg.C or more, the heat loss of the composite film due to vapor deposition heat at the time of metal vapor deposition becomes hard to generate.
