Patent number: 7381462Abstract: The invention relates to a biaxially-oriented opaque polypropylene multi-layer film, made from a base layer, at least one first intermediate layer arranged thereon and a first surface layer arranged on the first intermediate layer. The first intermediate layer has essentially no vacuoles. The first surface layer comprises at least 80 wt. % of a propylene/ethylene copolymer with an ethylene content of 1.2 to <2.8 wt. % and a propylene content of 97.2-98.8 wt. %, a melting point in the range 145 to 160° C. and a fusion enthalpy of 80 to 110 J/g. The base layer comprises vacuoles and has a density in the range 0.35 to 0.6 g/cm3. The invention further relates to the use of said film for the in-mould labeling of containers made from thermoplastic polymers.Type: GrantFiled: July 23, 2003Date of Patent: June 3, 2008Assignee: Treofan Germany GmbH & Co. KGInventors: Karl-Heinz Kochem, Albert Lauer, Mathias Roth, Wilfrid Tews

Patent number: 7381454Abstract: A tubular product has a tubular base layer, a tubular innermost layer made of plastic by continuous extrusion, and a tubular tie layer of foamed plastic between and adhered to the base layer and the innermost layer. The tie layer is made of melt processable adhesion plastic, is extruded simultaneously with the innermost layer against the base layer, and has better adhesions to the base and innermost layers than the base and innermost layers have to each other.Type: GrantFiled: December 18, 1997Date of Patent: June 3, 2008Assignee: Uponor B.V.Inventors: Kari Kirjavainen, Jyri Järvenkylä

Patent number: 7316841Abstract: An eraser is constituted by an elastic material containing a rubber component or a resin component, and a skeleton structure for reinforcing the elastic material, and the skeleton structure is made from a porous structural material such as from an organic polymer that is broken when rubbed. Void portions in the porous structural material of the skeleton structure contain the elastic material of the eraser composition. Here, the skeleton portions of the skeleton structure may have an average thickness of 1 to 100 ?m, and the void portions may have an average pore size of 10 ?m to 3 mm. The eraser may have a surface hardness of 50 to 80, and also a sticking strength of 1.5 to 20 (kgf).Type: GrantFiled: August 24, 2000Date of Patent: January 8, 2008Assignee: Sakura Color Products CorporationInventors: Shinichiro Hayashi, Ryuzo Yamamoto
