Polypropylene raffia, or PP raffia is a packaging material made from weaving ribbons of oriented polypropylene. It is named after the raffia palm, which the packaging emulates to some extent. Polypropylene raffia is considered to be a "widely used material for atmospheric capture".[1]
Today's most widely used material for atmospheric capture is polypropylene raffia, also called "raschel," which is a material classified under a class of mosquito netting fabric types (manufactured using Raschel knitting machines).
