Film becomes soft and sticky at about 130°F to 150°F (68°C)
Protect the integrity of research applications with a tight moisture- barrier that holds a strong seal and doesn't release, despite off-gassing Flexible and self-sealing material allows it to cling around irregular shapes and surfaces Reduce the risk of tampered data with a covering that is odorless, colorless and semi-transparent Prevents moisture and volume loss due to material composition and tight seal Resistant up to 48 hours against many polar substances.
Stretches more than 200% of original length

What is Parafilm?
Parafilm M Laboratory Film is a paraffin plastic film which typically comes in rolls with square demarcations printed on a paper backing. It is a ductile, malleable, waterproof,
odorless, translucent, and cohesive thermoplastic, making it extremely versatile under a number of conditions. Originally commercialized in the 1930s and intended for map mounting, Parafilm was quickly adopted by lab scientists for a myriad of uses.
How is Parafilm used?
Parafilm is most commonly used for sealing and protecting vessels such as test tubes, cuvettes, and petri dishes.
Since Parafilm is both stretchy and self-sealing, it is easily used on lab containers of all shapes and sizes.
Beyond these typical lab applications, many additional uses have taken advantage of the hydrophobic nature of the film. For instance, beads of aqueous liquid can be "dotted" on the surface, thereby making those samples easier to load into electrophoresis gels and other devices. In fact, any technique involving microliter volumes of aqueous solution can theoretically be performed using Parafilm. Of course, there are notable exceptions such as Polymerase Chain Reaction (PCR), which require sterile conditions to prevent the risk of contamination. Parafilm is also permeable by gasses such as oxygen, carbon dioxide, and water vapour.
Parafilm Outside the Lab
Interestingly, Parafilm has a prolific role in multiple areas outside of the traditional lab. A few notable uses include:
In horticulture, as a 'grafting tape' to wrap plant grafts together and prevent drying
In agriculture, as a protective layer on the stems of freshly cut produce such as bananas to extend their shelf life.
In art, as a non-adhesive masking material during airbrushing to protect the finish.
In entomology, as a membrane to feed hematophagous insects such as mosquitoes and bedbugs.
And in medical diagnostics, as a low-cost way to produce point-of-care diagnostics in developing countries where
expensive equipment and tests are not accessible.
Parafilm not only serves a variety of traditional laboratory functions, but it has many adopted uses in a diverse range of
fields as well. It will be interesting to see what other engagements Parafilm will entertain in the future.
