- Moisture-proof film molds to surface and protects the integrity of research applications with a tight moisture-barrier that holds a strong seal and doesn't release from glassware, despite off-gassing
- Non-toxic and free from plasticizers, film is primarily composed of polyolefins and paraffin waxes offering good resistance against acids, alkalis and some organic solvents – use not recommended with acetone, diethyl ether or tetrachloride
- Reduce the risk of tampered data with a covering that is odorless, colorless and semi-transparent
- Prevents moisture and volume loss due to material composition and tight seal
- Flexible and self-sealing material allows it to cling around irregular shapes and surfaces
- Stretches to more than 200% of original length
- Resistant for up to 48 hours against many polar substances such as saline solutions, inorganic acids and alkaline solutions
