Parafilm® M Sealing Film, 4 Inch x 125 Foot

A wider 4-inch by 125-foot roll of Parafilm® M covers larger glassware in a single wrap — moisture-proof film that molds to surfaces, holds a strong seal despite off-gassing, and stretches beyond 200 percent of its length.

Non-toxic and free of plasticizers, it resists many polar substances for up to 48 hours while staying odorless, colorless, and tamper-resistant. The extra width suits flasks and larger vessels across test tubes, beakers, vials, and petri dishes.

Key Benefits

• 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
