Abstract: The present disclosure provides a process. In an embodiment, the process includes providing pellets of a regrind material. The regrind material is a post-consumer recycle multilayer film (PCR multilayer film) having at least three layers. The PCR multilayer film is composed of (i) a polyethylene layer, (ii) a polyamide layer, and (iii) a tie layer. The tie layer is composed of maleic anhydride grafted substantially linear ethylene polymer (MAH-g-SLEP) having a Mw/Mn from 1.5 to less than 3.5 and a melt index from 0.5 g/10 min to less than 25 g/10 min. The process includes extruding the pellets to form an extrudate, molding the extrudate, and forming, with the extrudate, a molded article having a surface. The surface of the molded article has a surface roughness value, Sa, less than 1000 nm and a root mean square roughness value, Sq, less than 1400 nm.

Abstract: The present disclosure provides a support system. In an embodiment, the support system includes a top plate and a base plate. The top plate and the base plate have a common outer perimeter. The support system includes a support structure. The support structure supports the top plate above the base plate. The support system includes a pair of parallel rails. The parallel rails extend from the top plate outer perimeter to a closed end at a center portion of the top plate. The pair of parallel rails defines a channel. The support system includes a protrusion on each respective rail. Each protrusion extends into the channel in mirror-image relation to each other. The protrusions are located a fitment width distance away from the closed end. The protrusions and the closed end together define a filling position. The support system includes a fitment for a flexible container in the channel.
