Parafilm M Sealing Film 20″ x 50 ft

A Semi-Transparent, Flexible, Thermoplastic Film with Two-Way Stretch
Parafilm is a versatile, flexible, and waterproof laboratory film used extensively in scientific, medical, and industrial settings for sealing and protecting containers. Made from a blend of waxes and polyolefins, Parafilm can stretch up to 200% of its original size, providing a tight, moisture-resistant seal over test tubes, beakers, flasks, and petri dishes. This adaptability makes it an excellent choice for covering irregularly shaped containers and ensuring the contents are protected from contamination and evaporation.
