Nonplastic → It is formed from "non-" (meaning not) and "plastic" (from Greek "plastikos", meaning capable of being shaped or molded). The word "nonplastic" refers to something that is not capable of being shaped or molded.
Think of 'non-' meaning 'not' and 'plastic' meaning 'capable of being shaped' — so nonplastic means something that cannot be shaped.
