Skived copper heat sinks offer the maximum heat dissipation in applications that have high airflow and small space. The thermal conductivity of copper (~400 W/m-K) is the highest among all the commercial metals, and the skiving technology allows the heat sinks to have very thin fins http://www.baoyuechina.com/skiving-machine/copper-skiving-machine/

Polypropylene or PP is a low cost thermoplastic of high clarity, high gloss and good tensile strength. It has a higher melting point than PE, which makes it suitable for applications that require sterilization at high temperatures. It also has less haze and higher gloss. http://www.hengxinfilming.com/polypropylene-film/

Blown films, sometimes referred to as tubular films, are manufactured by extruding molten resin vertically through a circular die. Introducing air through the center of the die creates a bubble.
