Laboratory Wrapping Film - 2"x250'

Waterproof/moisture-proof film prevents sample evaporation, contamination; protects anhydrous materials. Can be folded repeatedly and twisted around sharp surfaces without rupturing. Stretched lengthwise at 70 degrees, this wrapping film increases approximately 200%. When tension is removed, film only partially returns to original length. Becomes more flexible and softer as temperature increases, in a dispensing box. Qualifying Standard: Parafilm.
