This film-shaped firing material is a film-shaped firing material containing sinterable metal particles and a binder component, in which, when the average thickness of the portion of the film-shaped firing material excluding the edge portion is deemed 100%, the average thickness of the edge portion of the film-shaped firing material is at least 5% thicker than the average thickness of the portion of the film-shaped firing material excluding the edge portion.

The invention provides a polyester composition in which the primary repeating units contain an aromatic dicarboxylic acid component (Component A) and an ethylene glycol component (Component C) and a long-chain alkyl dicarboxylic acid component having not less than 6 carbons (Component B) or a long-chain alkyl diol component having not less than 6 carbons (Component D), wherein a sum (WB+WD) of a relative amount (WB) of Component B as calculated based on a total number of moles of Component A and Component B plus a relative amount (WD) of Component D as calculated based on a total number of moles of Component C and Component D are within a range of 2-13 mol %. The invention also provides a polyester film prepared from the polyester composition and having excellent dimensional stability, as well as a magnetic recording medium utilizing the polyester film.

The present invention relates to a multilayer film including at least one film surface which has an increased surface roughness achieved by protrusion creating particles. The at least one film surface may have a surface roughness characterized by a coefficient of roughness (CR) of ≥0.02 or a Parker Print Surf roughness of at least 2 μm.

A polyester film laminated with other polymers to form a sheet. A laminated tube for liquid and paste products such as toothpastes, and the like can be manufactured from said sheet. The laminate comprises an outer polyethylene film, adhesive agent layers, a polyester film, and a composite polyethylene film comprising at least one co-extruded polyethylene layer sandwiched by at least one polyethylene film and an inner polyethylene film.

The invention relates to a packaging container (1, 2) for loose or free-flowing filling material, said packaging container consisting of plastic monofilm or composite film with at least one layer of plastic and forming, in a filled and closed form, a wrapping of the filling material with two mutually opposing main walls (3, 4) which act as bearing faces in a stack with other filled packaging containers and consist of thermoplastic, at least on the outer surfaces (15) thereof. The packaging container according to the invention is designed to be stackable in a non-slip manner but also easily removable from the stack and to this end, for practical production and processing, is designed such that the two surfaces (15) are embossed for a surface roughness having a roughness depth of 20-40 μm.

The present utility model provides an easy-to-clean protective film, which belongs to the technical field of protective films for vehicles and other vehicles, and can solve the problems that lasting scratches are easily caused to the existing vehicle coatings and surface stains are not easy to clean. The easy-to-clean protective film provided by the present utility model comprises a polyvinyl chloride (PVC) bottom film and an easy-to-clean layer consisting of silicon dioxide particles, wherein the water contact angle of the easy-to-clean layer is small and thus the adhesive force of dust and oil stains can be reduced. After the surface of the easy-to-clean layer is contaminated by dust and oil stains, the dust and oil stains can be easily cleaned with a simple cleaning. The easy-to-clean protective film provided by the present utility model is suitable for use as protective coatings of various substrates, especially for attachment to the body surfaces of vehicles such as automobiles.

A prepreg includes composition elements [A], [B], and [C] described below, [A] a reinforcing fiber, [B] a thermosetting resin, and [C] a thermoplastic resin. [C] is present on a surface of the prepreg, [B] contains a first curing agent [b1] and a second curing agent [b2], and the reinforcing fiber of [A] that crosses over a boundary surface between a resin region containing [B] and a resin region containing [C] and that is in contact with both resin regions is present.

The invention relates to a method to produce a linerboard exhibiting a high bending resistance and a high compression strength, which in turn provides high resistance to interflute buckling and sagging in a thereof formed corrugated board. This is achieved by the inventive combination of an optimized fiber refining level of the furnish in each layer of the linerboard, the separate formation of the top layer and the use of a multi-layer headbox to form the two-layered ply. In addition, the linerboard made according to the invention provides good printing properties in a thereof produced corrugated board, especially in flexographic printing, without the fluting structure being negatively affected.

A composite cooling film including a reflective nonporous inorganic-particle-filled organic polymeric layer, an ultra-violet-protective layer or layers, and an antisoiling layer.

A surface-treated copper foil includes a treated surface, where the peak extreme height (Sxp) of the treating surface is 0.4 to 3.0 μm. When the surface-treated copper foil is heated at a temperature of 200° C. for 1 hour, the ratio of the integrated intensity of diffraction peak of (111) plane to the sum of the integrated intensities of diffraction peaks of (111) plane, (200) plane, and (220) plane of the treating surface is at least 60%.
