Polypropylene

Polypropylene is a hard wearing material which offers excellent chemical resistance and low friction. As well it can withstand constant machinery vibration and is impermeable to water and will not taint sensitive substances.

These properties make it ideally suited to many applications, including packaging which involves foodstuffs and liquids.
