Cellophane

Chemical Properties

Transparent, strong, flexible, and highly resistant to grease, oil, and air. The base cellulose film is modified by softeners, flame-resisting materials, and dyes, also by coating with other materials. On exposure to heat the untreated film loses strength at 149C, decomposes at 176–204C, does not melt, burns readily, and is not self-extinguishing.

Uses

Wrapper or protective package for fabricated articles and industrial applications.

Definition

Film produced from wood pulp by the viscose process.

Hazard

Flammable, moderate fire risk.

Safety Profile

Questionable carcinogen with experimental tumorigenic data by implant. See also POLYMERS. When heated to decomposition it emits acrid smoke and irritating fumes.
