    摘要: A hydrogenated block copolymer containing polymer blocks (A1) and (A2) each mainly containing an aromatic vinyl compound-derived structural unit and polymer blocks (B) and (C) each mainly containing a conjugated diene compound-derived structural unit, at least one of the polymer blocks (B) and (C) being present between the polymer blocks (A1) and (A2), the hydrogenated block copolymer having a total content of the polymer blocks (A1) and (A2) of 5 to 30% by mass, a 3,4-bond and 1,2-bond content in the polymer block (B) of 1 to 40% by mole, a 3,4-bond and 1,2-bond content in the polymer block (C) of 50 to 100% by mole, and a mass ratio [(C)/(B)+(C)] of the polymer block (C) to the sum of the polymer blocks (B) and (C) of 26/100 to 63/100.

    摘要: Provided is a heat-shrinkable multilayer film having high strength and excellent followability to its contents.
    The heat-shrinkable multilayer film according to the present invention is composed of at least three layers of a surface layer (a) including a thermoplastic resin; an intermediate layer (b) including a polyamide-based resin; and a surface layer (c) including a sealable resin. (A) The load per unit width at 10% elongation is 0.70 N/mm or less in both a longitudinal direction (MD) and a transverse direction (TD) in a tensile test at 90°C. (B) The puncture strength per unit thickness is 0.200 N/µm or greater.

    摘要: A decorative film having: a pattern display layer formed by a transparent heat-resistant layer and a printed layer on a surface of the transparent heat-resistant layer to provide a first pattern, and the pattern display layer having a first side and a second side opposite to the first side; an extrusion-embossed microstructure layer formed on a surface of the second side of the pattern display layer and having a microstructure to provide a second pattern; and a reflective layer overlying the microstructure; when the decorative film is in use, an observer can see a display pattern composed of the first pattern and the second pattern on the first side of the pattern display layer. In addition, the present invention also proposes a packaging material using the decorative film and a label sticker using the decorative film.
