DescriptionCellophane is a plastic made of regenerated cellulose. It is a plant product and biodegradable.
HistoryCellophane was patented in 1912 and became commercially available that year. Since the 1960s it has been replaced by other plastic films. However, because of its biodegradability, nowadays it is increasingly used again.
Production, Application, AppearanceCE is only produced as film and is often transparant. It makes a rustling noise and feels quite hard and smooth. It is used as packaging film, especially for cigars, food wrapping, and as a base for self-adhesive tapes (Sellotape, Scotch Tape).
Density: 1.50-1.52 g/cm3
Melting point: 175-205 °C
Glass transition temperature: ??°C
Identification propertiesCell structure (foam): not applicable
Smell: no particular smell
Touch: (no) characteristic touch
Sound: produces a crackling sound
UV-radiation (when clear): illuminates yellow
Polarizing filters (for clear CE): produce prismatic colours - reversing the effect of the filters
ProcessPhoto-oxidation (degradation by light), atmospheric degradation, soiling (electrostatic).
DetailsIs not considered a problem plastic.
SymptomsYellowing, loss of mechanical properties resulting in tears.
RecommendationsUV-RADIATION: keep below 75 µW/lm UV filter for daylight and fluorescent light - reduce intensity
LIGHT: 1 just noticeable change in approx. 30 Mlx.h Moderate light dose. Control intensity and exposure time.
OXYGEN / OZONE: ambient conditions
TEMP: common indoor conditions 10-30°C
RH: common museum conditions 40-60% RH fluctuations: setpoint ±10% or ±5% when allowing seasonal fluctations between 35-65%
