A method for producing a multilayer member having a first member containing a crystallizable thermoplastic resin, an adhesion layer, and a second member includes performing a dry treatment on a surface of the first member containing a crystallizable thermoplastic resin so as to satisfy conditions A and B, applying an adhesive to the surface of the first member to form an adhesive layer on the surface, and adhering the second member to the adhesive layer. (A) The ultimate temperature of the first member is lower than the peak temperature of endothermic peak obtained by DSC of the crystallizable thermoplastic resin. (B) The high temperature holding time of the first member is less than 3.0 seconds, which is when the first member is continuously held at a temperature not lower than a temperature at the starting point of the endothermic peak obtained by DSC of the crystallizable thermoplastic resin.

A multilayer film is herein provided. The film, which is useful for packaging, comprises: a core barrier layer having an outer side and an inner side, said core barrier layer comprising one or more barrier polymers that exhibit moisture and/or oxygen barrier properties, wherein said barrier polymer is optionally coupled to a slow crystallizing polyamide or a polymer blend thereof; an outer layer bonded to the outer side of the core barrier layer comprising a rigid polymer having an inherent viscosity (IV) in the range of about 3.2 to 4.7, wherein the outer layer optionally comprises slow crystallizing polymer (SCP) or a polymer blend thereof; and a sealant layer bonded to the inner side of the core barrier layer comprising one or more polyolefins sufficient to provide a seal.

The surface roughness of a polymer film laminated to a metal substrate can be improved through the use of sufficient heating after application of a wax layer to the polymer film. In some cases, a thin liquid film or layer of a waterborne wax dispersion can be applied to the surface of a metal substrate laminated with a polymer film. After heating the polymer film and wax layer to a point at which the polymer film and wax layer begin to become molten, the surface roughness of the polymer film can become improved due to the presence of the wax.

Infrared transmitting glasses bonded into an optical element without interlayer voids by stacking at least two different infrared transmitting glasses inside a vessel where each glass has a different refractive index, a different dispersion, or both, and where the glasses all have similar viscosities, thermal expansion coefficients, and glass transition temperatures; placing a weight on top of the stack; applying a vacuum to the vessel; applying an isostatic pressure of at least 1500 psi; and after releasing the isostatic pressure, annealing at a temperature within 10 C. of the glass transition temperature at a pressure between 0 and 1000 psi. Applying the vacuum, applying the isostatic pressure, and annealing are done sequentially and with no intermediate transitions to ambient temperature or pressure.
