Reinforced thin film for flexible packaging

The invention provides a thermoplastic film comprising: a base film wherein the base film comprises a stretchable polyolefin material comprising one or more layers; and a plurality of extruded fiber elements; wherein the extruded fiber elements are located on at least one surface of the base film; wherein the extruded fibers form one or more protrusions relative to the plane of the base film; wherein at the location where the fiber elements are provided on the base film, a domain of a material mixture comprising the base film material and the fiber material is present between a domain of pure base film material and a domain of pure fiber material, and wherein the average thickness of the base film is less than the average thickness of the protrusion.

Shim for a compression mold with improved sealing

A shim for a compression mold for manufacturing a component from reinforced plastic, typically from SMC, comprising a fixed molding element, a mobile molding element, and a mobile shim that can be moved by an actuator. The mobile shim comprises a conventional part made of steel but also a part made of a high expansion material with a mean coefficient of expansion that is high enough that its own expansion at the molding temperature places the shim in compression against the molding element and seals against this element, thus eliminating flash on the molded part. This material is advantageously a polyetheretherketone, or PEEK. A mold comprising this shim and a compression molding method are also disclosed.

FUEL TANK

A fuel tank includes: a tank main body made of a resin material; and a cover member which is formed using threads made of a fiber-reinforced composite material containing a thermoplastic resin fusible to a surface of the tank main body. The cover member has a twill weave structure at least in its portion fused to the upper surface of the tank main body. The threads each have a core-sheath structure in which a fiber made of a polypropylene resin is coated with a polyethylene resin.

METHOD OF MANUFACTURING POLYMER COMPOSITES COMPRISING AGRO-WASTE PARTICLES

A method of manufacturing a polymer composite comprising a polymer phase and agro-waste particles dispersed in the polymer phase, wherein the polymer phase is preferably obtained from polyolefin containing waste plastics, and the agro-waste particles are preferably obtained from date palm wood flour particles. Various combinations of embodiments are provided.
