Parafilmn.

Brit.

/ˈparəfɪlm/, U.S.

/ˈpɛrəˌfɪlm/

Forms: also with lower-case initial.

Origin: Probably formed within English, by compounding. Etymons: paraffin n., film n.

Etymology: Probably < para- (in paraffin n.) + film n., on account of paraffin being one of the constituents of the coating of the film (compare A. H. Warth Chem. & Technol. Waxes (1947) ix. 443).

A proprietary name for: any of various thermoplastic materials manufactured as sheets, membranes, etc., for wrapping or sealing.
