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.

Abstract: The present disclosure provides a process. In an embodiment, a process for producing a packaging article includes providing a body having a geometric shape and composed of a three-dimensional random loop material (3DRLM). The 3DRLM is composed of an olefin-based polymer. The body has a sleeve with opposing ends on respective opposing surfaces of the body. The sleeve extends through an interior portion of the body and has an opening at each respective end. Each opening has a closed width. The process includes providing a product having an insert shape. The insert shape has an insert width that is greater than or equal to the closed width of the sleeve opening. The process includes inserting the product into the sleeve.

The packaging article includes a product having an insert shape. The insert shape has an insert width that is greater than or equal to the closed width of the sleeve opening. A portion of the 3DRLM moves from a neutral state to a stretched state when the product is inserted into the sleeve.
