Heathrow Scientific® Parafilm® M Sealing Film

Semi-transparent, flexible, thermoplastic film with two-way stretch. Non-toxic and free from plasticizers, 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. Protect the integrity of research applications with a tight moisture-barrier that holds a strong seal and doesn’t release from glassware, despite off-gassing. 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 more than 200% of original length. Resistant up to 48 hours against many polar substances such as saline solutions, inorganic acids and alkaline solutions. Two color options available in 2” rolls (natural and purple) for color coding purposes. Disposable.
