DuraSeal® Sealing Film, Diversified Biotech


DS4-500 DS2-500 DS12-250 DS4-250 DS5-150
Durable, heat-resistant stretch sealing film is polyethylene-based and resists all caustic agents and organic solvents

DuraSharp® Shears are ideal for cutting DuraSeal® film. Shears are sold separately.

Allows containers to be incubated in boiling water baths without suffering the characteristic melting of paraffin-based alternatives. Film stretches symmetrically over a container and contracts inwardly around container opening or neck to provide a waterproof seal. Film can be elongated 500–800% before tearing.
