A method of refining a polymer resin material is provided. The method comprises melting and subjecting the resin material to shear stresses in a range of 250 kPa to 400 kPa to form a refined resin material. The refined resin material may be extruded, solidified and cut into reduced microgel resin pellets, which may be subsequently melted and extruded to form a reduced microgel film.

Processing aid for aiding in orienting an extruded film layer including a preponderance, by weight, of a high crystalline polypropylene is a crystalline polypropylene wax. An oriented film layer including a blend of crystalline polypropylene wax and high crystallinity polypropylene homopolymer is part of the invention. The invention includes a method of forming an oriented film layer including a preponderance by weight of a high crystallinity polypropylene and includes the steps of blending a high crystallinity polypropylene with a crystalline polypropylene wax, directing the blend through an extruder to form a film layer and then orienting the film layer. The invention includes a biaxially oriented, multi-layer film including a base layer and at least one skin layer. The base layer includes a blend of crystalline metallocene catalyzed polypropylene wax and a high crystallinity polypropylene.

Multilayer polyethylene (PE) geomembrane liners for unconventional thermal conditions and methods of making them are disclosed. The liners have N co-extruded stacked layers, each layer being made from a PE masterbatch composition comprising a given amount of PE resin and additives, and of a PE metallocene based resin free of acid neutralizer compounds. Also disclosed are customized multilayer PE geomembrane liners of N co-extruded stacked layers, each layer being made from a PE masterbatch comprising a specific additive providing specific behaviour property to the layer; wherein at least two of the N layers comprise a different specific additive in order to provide a geomembrane liner having at least two layers with different behaviour property. The liners have a water-bath aging performance for about 6 months immersion at about 80°C per ASTM D5322 - modified for water, such that about 80% of high pressure OIT value retained per ASTM D5885.
