A protected substrate includes a planar substrate having a surface and a burn-off temporary protective layer positioned over at least a portion of the surface. The burn-off temporary protective layer includes a wax, a polyolefin, a polyester, a polycarbonate, a polyether, or some combination thereof. The burn-off temporary protective layer is removable by a heat treatment process that does not substantially damage the surface. Various other protected substrates and methods for protecting a substrate are also disclosed.

The present invention is a liquid-repellent film that exhibits an excellent liquid repellency, and a packaging material of which a surface is formed of the same. The liquid-repellent film comprises: an undercoat part (90) formed unevenly on the substrate surface by microparticles (70) and a thermoplastic resin (80); and a topcoat part (60) having: (i) a minute uneven structured part that includes hydrophilic microparticles (20) having a smaller particle size than the microparticles (70); (ii) a liquid-repellent moiety (40) that bonds to the surface of the minute uneven structured part; and (iii) a binder resin (50) that is present between the surface of the undercoat part (90) and the minute uneven structured part, and is distributed to cover the bonding part of the minute uneven structured part and the liquid-repellent moiety (20).

The present invention relates to a fully moisture-tight multilayer material, which is also able to absorb, retain and not release the absorbed moisture or free water into the formulations containing pharmacological active substances and/or instable components with biological activity and/or effervescent and/or easily perishable formulations; said material being useful for preparing bags, envelopes and sachets for packaging food, dietary and cosmetic products, medical devices and medicinal products. The multilayer material of the present invention is a multilayer material that is useful for preparing containers in the form of bags, envelopes, sachets and sticks coming into direct contact with the formulations of the food, dietary and cosmetic products as well as of the medical devices and medicinal products in the form of e.g. lactic bacteria and/or bifidobacteria in powders or granules, either dried or freeze-dried.

Provided is a packaging material for batteries, which has excellent insulating properties. A packaging material for batteries, which is formed of a laminate that is obtained by sequentially laminating at least a base layer, a bonding layer, a metal layer and a sealant layer, and wherein the base layer comprises a resin layer A that is formed of a thermoplastic resin having a volume resistivity of 1×10.sup.15 Ω.Math.cm or more.

A film-shaped packaging material for a cell in which a coating layer is provided as the outermost layer instead of a substrate layer and an adhesive layer in a conventional film-shaped packaging material for a cell, thereby making it possible to produce a thinner film; wherein the packaging material is provided with exceptional moldability and insulation performance and enables lead time to be reduced. The packaging material is a laminate having at least a coating layer, a barrier layer, and a sealant layer in the stated order, the coating layer including a single- or multiple-layer configuration formed by a cured product of a resin composition containing a heat-curable resin and curing accelerator, the laminate having a piercing strength of at least 5 N, as measured in compliance with JIS 1707:1997, and the coating layer having a breakdown voltage of at least 1.0 kV, as measured in compliance with JIS C2110-1.

An apparatus includes first, second, and third layers. The first layer includes a plurality of flanges. The second layer includes a deformable membrane. The second layer is connected to the first layer along a first major surface of the deformable membrane. The third layer is connected to the second layer along a second major surface of the deformable membrane opposite the first major surface. The third layer includes a first series of internal structures.

Disclosed herein films and packages formed therefrom for packaging oxygen-sensitive products. The films include a product contact layer comprising COC and catalyst. Introduction of a gas flush including hydrogen gas to a package made from said films helps provide for the catalytic combination of molecular hydrogen and molecular oxygen to remove oxygen from a headspace of the package.
