A method of recycling a mixed plastic waste comprising plastics having different melting temperatures includes conveying the mixed plastic waste through an extruder such that at least some of the higher melting point plastic is passes through the extruder without melting and is present in the extrudate as solid material.

A multi-layer film or laminate is disclosed in which an olefinic polymer layer is adhered to a metal foil layer without the use of an adhesive. The olefinic polymer layer contains an olefinic polymer in combination with a transition metal salt. The addition of the transition metal salt greatly improves the peel strength of the laminate.

A laminate which comprises a first resin layer and a second resin layer, and wherein: a resin constituting the first resin layer and a resin constituting the second resin layer are incompatible with each other, the first resin layer contains a polyolefin; the second resin layer contains a first thermoplastic resin and a second thermoplastic resin; and the first thermoplastic resin and the second thermoplastic resin are incompatible with each other, while having different solidification temperatures.

A multilayer film includes an extruded first polymer layer confined between extruded second polymer layers. The first polymer layer includes a high aspect ratio crystalline lamellae. The multilayer film is substantially impermeable to gas diffusion.

Disclosed herein are a thermoplastic resin sheet having excellent mechanical strength and excellent conformability during molding, a laminated sheet using such a thermoplastic resin sheet, and a molded body. The thermoplastic resin sheet includes a thermoplastic resin containing a polyolefin resin, a polyamide resin, and a compatibilizer, wherein the compatibilizer is a modified elastomer having a reactive group that reacts with the polyamide resin. The laminated sheet includes a base layer containing a polyolefin resin and the thermoplastic resin sheet bonded to one surface of the base layer. The molded body includes a base body containing a polyolefin resin and the thermoplastic resin sheet or the laminated sheet bonded to one surface of the base body.

Polymer-based sheet materials having a variegated appearance are provided. The polymer-based-sheet material may have a core with one or more caps. The cap(s) may be on a first primary surface, a second primary surface, and/or sides. The variegation may be within and/or on the cap and/or the core. Methods, systems, articles, and materials effective for a polymer-based sheet material having a variegated appearance are provided.

A polyolefin material that is formed by solid state drawing of a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and nanoinclusion additive is provided. The nanoinclusion additive is dispersed within the continuous phase as discrete nano-scale phase domains. When drawn, the nano-scale phase domains are able to interact with the matrix in a unique manner to create a network of nanopores.

Provided is a resin composition having high conductivity without blending a high concentration of carbon fibers. The resin composition includes a thermoplastic resin, carbon black, and carbon fibers coated with a conductive liquid, wherein a content of the thermoplastic resin is 65 mass % or more and 94.9 mass % or less, a content of the carbon black is 5.0 mass % or more and 30 mass % or less, and a content of the carbon fibers coated with a conductive liquid is 0.1 mass % or more and 5.0 mass % or less.

It discloses a lignin enhanced wood-plastic composite, belonging to the field of polymer based composites. The wood-plastic composite is composed of one or more of plant fiber, lignin, a recycled thermoplastic plastic, mineral powder and a processing aid, and is processed by a screw granulating extrusion process. Compared with the prior art, the mechanical properties, heat stability and aging resistance of a wood-plastic material are improved by adding lignin into the wood-plastic material according to the present invention.

An ion exchange resin membrane or an ion exchange precursor resin membrane having a thickness of 25 microns or less and having an orientation ratio of 1.5 or less; which may be produced by co-extruding an ion exchange precursor resin with an incompatible polymer to form a multilayer film having a layer of the ion exchange precursor resin supported on a layer of the incompatible polymer. The layer of incompatible polymer is then removed from the layer of ion exchange precursor resin to provide the ion exchange precursor resin membrane. The ion exchange precursor resin membrane may be converted to an ion exchange resin membrane by hydrolysis, and subsequent acidification if desired.
