Over standard laboratory stretch films, Dura Seal Stretch Film, a strong, heat- and solvent-resistant stretch film, offers a number of significant advantages. Due to its better heat resistance, containers can be heated in boiling water baths without melting as they would with paraffin-based substitutes. This is very effective and safe to use. Dura Seal Stretch Film is made of polyethylene and contains no adhesives, it is resistant to almost all caustic substances and organic solvents. This has excellent cohesion, stretching, and tear resistance.
