Parafilm 4" X125' Roll

Parafilm 4" X125' Roll

Parafilm® 4" × 125' Roll is a flexible, self-sealing laboratory film designed to securely wrap and protect a wide range of labware. Made from a polyolefin-based thermoplastic, it stretches up to 200% of its original length, allowing it to conform tightly to irregular surfaces such as flasks, beakers, test tubes, and petri dishes. Its semi-transparent finish makes it easy to monitor contents while maintaining a clean, professional appearance in laboratory environments.

This sealing film is moisture-resistant and gas-permeable, making it ideal for short-term sample protection, evaporation control, and contamination prevention. It adheres without adhesive, relying on pressure and stretch to form a tight seal that’s easy to apply and remove without leaving residue. The 4-inch width and 125-foot roll length provide ample material for high-volume use, supporting both research and routine lab operations.

Parafilm® is widely used in clinical, pharmaceutical, and academic labs for sealing reagent bottles, culture plates, and temporary sample storage. Its −45°C to +50°C temperature tolerance ensures reliable performance across refrigerated and ambient conditions. Whether used for daily lab tasks or specialized protocols, Parafilm® offers a cost-effective, versatile solution for maintaining sample integrity and lab hygiene.
