Parafilm is a semi-transparent, flexible film composed of a proprietary blend of waxes and polyolefins. Parafilm is a registered trademark of Bemis Company, Inc, headquartered in Neenah, WI (United States). It is a ductile, malleable, non-toxic, tasteless & odorless self-sealing thermoplastic.
Because it melts at a low temperature, Parafilm M is not safe for use in an autoclave.
Parafilm M is wrapped around the freshly cut crown of bananas, pineapples and other produce instead of using fungicides or other coatings to prevent rot.
Florists use Parafilm Stem Wrap to extend the flower's life by protecting moisture in the stem as a floral tape.
Horticulturalists use Parafilm Grafting Tape in grafting. Several grafting styles call for wrapping a graft to hold it together, and sealing it to prevent drying and Parafilm Grafting Tape does both. In this context Parafilm is also known as grafting tape.
A new application of Parafilm M is to make paper-based microfluidic devices. Paper-based microfluidic devices are considered a suitable way to fabricate low-cost point-of-care diagnostics for developing countries and areas where expensive medical instrumentation is not accessible. Digital microfluidic devices can also use it as the electrode insulator and hydrophobic layer
