General description

Durable, heat-resistant, solvent-proof laboratory sealing film, that is chemically resistant, heat resistant & microwave compatible, that creates a tight, tear resistant seal. This LDPE stretch film, has substantial advantages over common laboratory stretch films. Its’ superior heat-resistant feature allows for containers to be incubated in boiling water baths without suffering the characteristic melting of paraffin-based alternatives. Since DuraSeal is polyethylene based and free of any adhesives, it resists essentially all caustic agents and organic solvents.

It is easy to use, there is no inter-leaf paper to strip away, just stretch the film symmetrically over a container opening and the 1.5mil thick film contracts inwardly around the opening or neck of the container to provide a drum-tight, water-proof seal. The film can be elongated 500-800% before breakage, minimizing the incidence of tearing during stretch sealing. The film clings to itself, especially after stretching so the free edges of the film may be stretched around the container to secure the container edges.
