The dicarboxylic acid component (a) contains 60 mol % or more and 100 mol % or less of terephthalic acid. The diamine component (b) contains 60 mol % or more and 100 mol % or less of 1,9-nonanediamine and 2-methyl-1,8 octanediamine. The fiber-reinforced resin composite sheet has a volume content rate Vf of the reinforcing fibers of 20% or more and 70% or less and a thickness of 20 μm or more and 70 μm or less.

A multilayer laminate (100) comprises an oriented polyethylene film (102), a biaxially oriented film (104) adhered to the oriented polyethylene film (102), a barrier film (106) adhered to the biaxially oriented film (104), and a multilayer polyethylene (PE) film (108) adhered to the barrier film (106). The biaxially oriented film (104) comprises one or more components selected from biaxially oriented polyamide (BOPA), biaxially oriented polyethylene terephthalate (BOPET), and biaxially oriented polypropylene (BOPP).

A spunbond non-woven fabric includes a nonbonded projected part and a bonded recessed part. Bending resistance in a machine direction of the spunbond non-woven fabric is 20 mN or more and 40 mN or less, and in a non-woven fabric cross-section, a thickness from one surface to another surface of the projected part is determined to be t.sub.A, a thickness from one surface to another surface of the recessed part is determined to be t.sub.B, and respective distances from one surface of the projected part to one surface of the recessed part are determined to be t.sub.C and to (t.sub.C<t.sub.D), and the spunbond non-woven fabric has a relation represented by formulas (1) and (2) below:

0.5≤1−t.sub.B/t.sub.A<1.0  (1)

0.35<t.sub.C/t.sub.D<0.65  (2).

The present invention provides a laminated sheet for manufacturing a packaging container. The laminated sheet comprises a pair of plastic sheets, a barrier sheet, a barrier region, an easily peelable region, and a fixing region. The barrier sheet has flexibility and is disposed between the pair of plastic sheets. The barrier region is formed by overlapping the pair of plastic sheets and the barrier sheet with each other. The easily peelable region is provided in the barrier region. The fixing region is located in a circumference of the easily peelable region, in which the pair of plastic sheets are fixed to each other directly and/or via the barrier sheet. A peel strength between the pair of plastic sheets and the barrier sheet in the easily peelable region is smaller than a direct peel strength between the pair of plastic sheets and/or a peel strength between the pair of plastic sheets via the barrier sheet in the fixing region. This improves recyclability of a packaging container having gas barrier property.

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 present invention relates to a polypropylene composition comprising —10 to 50 wt. % of recycled polypropylene (R-PP) and/or linear polypropylene (L-PP); —40 to 89.95 wt. % of a high melt strength polypropylene (HMS-PP) having an F30 melt strength of more than 25.0 cN and a v30 melt extensibility of more than 205 mm/s, wherein the F30 melt strength and the v30 melt extensibility are determined according to ISO 16790:2005; and —0.05 to 10 wt. % of a nucleating agent (NA); a foamed sheet formed from the polypropylene composition; an article comprising the foamed sheet and a process comprising the step of forming the polypropylene composition. Furthermore, the invention is further directed to the usage of the polypropylene composition for the formation of foamed sheets.

A laminate includes a substrate layer and a heat-sealing layer. A fold of the laminate produced by a weight of a 2 kg roller has a folding angle of 20 to 55°, and a content of polyethylene in the laminate is 90% by mass or more. The folding angle may be 25 to 55°. The substrate layer may contain high-density polyethylene. The substrate layer may be a uniaxially oriented linear low-density polyethylene film or an unstretched film made of polyethylene.

Provided is a display protector including: a first transparent base layer having a first surface and a second surface which face each other; a second transparent base layer having a third surface and a fourth surface which face each other, and arranged so that the third surface faces the second surface; an intermediate stress relief adhesive layer arranged between the second surface and the third surface; a first outer stress relief adhesive layer over the first surface; a second outer stress relief adhesive layer over the fourth surface; and an ultra-thin glass (UTG) layer on the first outer stress relief adhesive layer.

A composite cover includes a generally rectangular main portion having four main portion edges about a perimeter of the main portion and having opposing top and bottom surfaces defining respective upward and downward directions, and four generally rectangular side portions each contiguous with and extending downward from a respective one of the main portion edges. The main portion and the four side portions generally enclose an interior space and are made of a sandwich structure comprising an interior layer of continuous fiber reinforcements and resin and an exterior layer of metallic foil bonded to the interior layer. A method of manufacturing the cover, having a desired shape generally of a five-walled open box, includes attaching a formed sheet made of metallic foil and having the desired shape onto a shaped composite preform disposed in the desired shape, wherein the shaped composite preform is made of continuous fiber reinforcements and resin.
