Durable, heat-resistant stretch sealing film is polyethylene-based and resists all caustic agents and organic solvents. 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.
DuraSharp® Shears are ideal for cutting DuraSeal® film. Shears are sold separately.
