Disclosed is a composition useful for forming blown films. The composition includes (a) an ungrafted ethylene-based polymer, (b) a nanocomposite containing a polyamide and montmorillonite, (c) a compatibilizer comprising a maleic anhydride grafted ethylene-methyl acrylate copolymer and/or a maleic anhydride grafted ethylene-butyl acrylate copolymer, and (d) optionally, an ethylene-vinyl alcohol (EVOH) copolymer. Also disclosed is a blown film made from a composition containing an ungrafted ethylene-based polymer, a nanocomposite containing a polyamide and montmorillonite, a compatibilizer comprising a maleic anhydride grafted ethylene-based polymer, and optionally, an EVOH copolymer. These films can have improved optical and/or mechanical properties compared to films made without the nanocomposite.

A panel is disclosed, including a first facesheet, a second face sheet, and a plurality of pultrusion-formed web structures. Each web structure has a middle support portion, a first end portion, and a second end portion. The first end portion of each web structure is attached to the first facesheet and the second end portion of each web structure is attached to the second facesheet. The middle support portion, first end portion, and second end portion of each web structure form a single monolithic structure.

Described herein is an additive manufacturing method of making a three-dimensional (3D) object with a polyamide composition comprising at least 50% by weight (wt %) of a polyamide comprising at least 50% by mol (mol %) recurring units of NH(CH.sub.2).sub.8C(O) and/or NH(CH.sub.2).sub.9C(O); from 0 wt % to 50 wt % of at least one reinforcing agent and from 0 wt % to 30 wt % of at least one additive, with excellent thermal stability. The present invention also relates to an article or composite material manufactured by the additive manufacturing method.

The present disclosure provides a polypropylene film including particles.

A method for manufacturing biotic gloves and a hypoallergenic biotic glove are provided. The method includes dipping the molds into a coagulant solution and performing a pre-vulcanization treatment using alkaline protease, ultraviolet irradiation, and polyols derived from cellulose materials. The latex-coated molds undergo drying, washing, vulcanization with specific curing agents and accelerators, chlorine washing, and a secondary dipping in polyurethane to form a hypoallergenic inner layer. The resulting gloves feature a multilayer structure, including a first layer, a second layer, and a third layer. The first layer includes nitrile butadiene rubber, chloroprene rubber, or isoprene rubber combined with polysaccharide biotic materials. The second layer includes a natural rubber layer or other synthetic rubber combined with polysaccharide biotic materials, and the third layer includes a polyurethane layer. The final gloves have a biotic content of 3-40%, a tensile strength of 14-40 MPa, and an elongation at break of 350-800%.
