Abstract: A method of fused filament fabrication (FFF) additive manufacturing comprises employing a thermoplastic blend comprised of high density polyethylene and a second thermoplastic polymer, wherein the second polymer is a low density polyethylene (LDPE), functionalized polyolefin or combination thereof and the amount of high density polyethylene to the amount of second thermoplastic polymer by weight is a ratio from 1.5/1 to 20/1. LDPE means a polyethylene that have been radically polymerized at high pressure. The method allows for the additive manufacturing article that retains the desirable mechanical properties of HDPE without experiencing the problems inherent in FFF printing of HDPE or use of solid fillers. In a particular embodiment, the additive manufactured article has a continuous phase and the second thermoplastic polymer is present as a discontinuous phase within the additive article manufactured article and the filament used to make the article.

Abstract: Laminate film structures including an adhesive layer having gas and moisture barrier properties are disclosed. The disclosed laminate film structures comprise films bonded together with an adhesive composition, the adhesive composition having barrier properties, e.g., controlling oxygen and/or water vapor transmission rates. The disclosed laminate film structures comprise films made from polymers and/or metallized polymers whereby the weight, thickness, and/or number of film layers has been reduced by using a barrier adhesive in place of a standard adhesive while still achieving similar barrier properties. Methods for forming laminate structures having a desired barrier performance are also disclosed, the methods comprising determining the desired barrier performance of the laminate structure, selecting a barrier adhesive, selecting two or more film layers, including at least a first film layer and a second film layer, applying the barrier adhesive on a surface of the first film layer, and bringing a surface of the second film layer into contact with the barrier adhesive applied on the surface of the first film layer, thereby forming the laminate structure having a desired barrier performance.

Abstract: The present disclosure provides a die assembly for producing a microcapillary film. The die assembly includes a first die plate, a second die plate, a plurality of multi-jackbolt tensioners connecting the first die plate to the second die plate, a manifold, and a plurality of nozzles. The manifold is located between the pair of die plates and defines a plurality of film channels therebetween. The plurality of film channels converge into an elongate outlet, wherein a thermoplastic material is extrudable through the plurality of film channels and the elongate outlet to form a microcapillary film. The plurality of nozzles are located between the plurality of film channels. The plurality of nozzles are operatively connected to a source of channel fluid for emitting the channel fluid between layers of the microcapillary film, whereby a plurality of microcapillary channels are formed in the microcapillary film.
