There is provided a metal-organic composite which exhibits synergistic improvement in thermo-mechanical properties when compared with either of the components alone. The composites of this invention can be readily fabricated into various shapes by conventional molding processes including injection or compression molding. As a result, the composites of this invention find a variety of applications in fabricating a variety of three dimensional articles including automotive parts among others.

Provided are a liquid crystal polymer (LCP) film and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and a ratio of a ten-point mean roughness relative to a maximum height (Rz/Ry) of the first surface is from 0.30 to 0.62. By controlling Rz/Ry of at least one surface of the LCP film, the peel strength of the LCP film stacked to a metal foil can be increased, and the laminate comprising the same can still maintain the merit of low insertion loss.

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.
