The present disclosure provides a method. In one embodiment, the method comprises providing pellets of regrind material. The regrind material is a post-consumer recycled 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 an Mw/Mn of from 1.5 to less than 3.5 and a melt index of from 0.5 g/10 min to less than 25 g/10 min. The method comprises extruding the pellets to form an extrudate, molding the extrudate, and forming a molded article having a surface from the extrudate. The surface of the molded article has a surface roughness value Sa of less than 1000 nm and a root-mean-square roughness value Sq of less than 1400 nm.
