Abstract
The present techniques provide multi-layer plastic structures and methods for making such. The multi-layer plastic structures include an inner surface made from a polyolefin resin, and resistant to environmental stress cracking, and an outer surface that includes a styrenic copolymer. The outer surface has a kinetic coefficient of friction with itself of 0.42 and a static coefficient of friction with itself of 0.44.
