Parafilm® M is a semi-transparent, flexible, thermoplastic film with two-way stretch.

• Creates tight moisture-barrier that holds a strong seal and doesn't release from glassware, despite off-gassing
• Reduces 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

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. Resistant up to 48 hours against many polar substances such as saline solutions, inorganic acids and alkaline solutions.
