COMPOSITE STRUCTURES FOR PACKAGING ARTICLES AND RELATED METHODS
The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.
PROCESS FOR PRODUCING RESINOUS PANEL
A process for producing a resinous panel which is for use as at least some of the front panel of an article, the process including (A) a step in which a resin sheet having a thickness of 0.5-10 mm is fixed to a working table and (B) a step in which the resin sheet is punched out by forcing a Thomson blade into the resin sheet approximately perpendicularly thereto from the side where the surface of the resin sheet is to be the outer surface of the article, thereby obtaining the front panel, wherein (C) the Thomson blade is a double-edged blade having an edge angle of 30-60 degrees. The resin sheet has a tensile modulus of preferably 1,500 MPa or greater. Preferably, the resin sheet includes a transparent resin sheet layer and a colored resin sheet layer in this order from the surface that is to be the outer surface of the article. The colored resin sheet is one which does not break when a DuPont impact test was conducted in accordance with ASTM-D2794 in a 0° C. environment under the conditions of a height of 50 cm, an impactor diameter of 1 inch, an impactor weight of 1 Kg, and a pedestal diameter of ½ inch.
Transparent conducting film laminate and processing method thereof
Provided are a transparent conducting film laminate to which a curl generated during a heating step and after the heating step can be controlled, and a method for processing the same. A transparent conducting film laminate comprises a transparent conducting film 20 and a carrier film 10 stacked thereon, wherein the transparent conducting film 20 comprises a transparent resin film 3, transparent conducting layer 4, and an overcoat layer 5 stacked in this order, the transparent resin film 3 having a thickness T.sub.1 of 5 to 25 μm and being made of an amorphous cycloolefin-based resin, the carrier film 10 is releasably stacked on the other main face, the face opposite to the face having the transparent conducting layer 4, of the transparent resin film 3 with an adhesive agent layer 2 therebetween, and a protection film 1 has a thickness T.sub.2 which is 5 times or more of the thickness T.sub.1 of the transparent resin film 3 and is 150 μm or less, and is made of polyester having an aromatic ring in its molecular backbone.
SEALANT FILM, LAMINATE FILM, AND PACKAGING MATERIAL
A sealant film is provided in which a surface resin layer (A), an adhesive resin layer (B), a release resin layer (C), and a heat seal resin layer (D) are laminated. The adhesive resin layer (B) contains a thermoplastic elastomer (b1) and a tackifier resin (b2). The release resin layer (C) contains 40% by mass or more of an ethylene ionomer (c1) with a polar group concentration exceeding 5.5 mol % in a resin component contained in the release resin layer (C). The release resin layer (C) further contains 0 to 60% by mass of an ethylene ionomer (c2) with a polar group concentration of 5.5 mol % or less in the resin component contained in the release resin layer (C). The heat seal resin layer (D) contains an ethylene resin (d1).
Polymer film containing an amorphous and a partially crystalline polyamide
The present invention relates to a polymer film (P) containing a polyamide composition (PC) that comprises an amorphous polyamide (A) and a semicrystalline polyamide (B) and to a method for producing the polymer film (P).

METHOD OF FORMING A BALLOON
A balloon formed from a lamination. The lamination includes a first layer, a second layer, a graphic design and a third layer. The first layer including from about 10 to about 90 wt. % crystalline polyester and from about 10 to about 90 wt. % of a formability enhancer to assist in increasing the polymeric chain flexibility. The formability enhancer has a melting point less than about 230° C. The first layer has a MD and a TD Young's Modulus of at least 10% lower than a crystalline polyester film in the absence of the formability enhancer. The second layer is a metallic barrier layer. The graphic design is printed onto a surface of the metallic barrier layer. The third layer is a sealant layer. The first layer is located between the second and third layers. The balloon contains a gas lighter than air.
