    Parafilm 4" X125' Roll

    PARAFILM® M is a versatile, self-sealing laboratory film designed to protect the integrity of sensitive research applications. Made primarily from polyolefins and paraffin waxes, it offers a tight moisture barrier that clings securely to glassware—even under off-gassing conditions. Its odorless, colorless, and semi-transparent composition ensures unobtrusive coverage, reducing the risk of contamination or tampered data. With the ability to stretch over 200% of its original length, PARAFILM conforms easily to irregular shapes and surfaces, making it indispensable in lab environments.

    Engineered for short-term chemical resistance, PARAFILM M withstands exposure to many polar substances—including saline solutions, inorganic acids, and alkaline solutions—for up to 48 hours. Its plasticizer-free formulation prevents moisture and volume loss, helping maintain sample integrity. Whether sealing flasks, petri dishes, or reagent bottles, this flexible film delivers reliable performance without requiring adhesives or complex tools. Ideal for laboratories seeking a clean, efficient sealing solution that adapts to diverse applications.
