Parafilm Sealing Film
Parafilm Sealing Film is a thermoplastic, flexible, self-sealing sheet material commonly used to seal flasks, tubes, petri dishes, etc. Parafilm is also used to further seal a lidded container against moisture for long-term storage. Due to its stretchable, moldable, waterproof, and self-adhering properties, Parafilm holds moisture loss to a minimum.
Originally, the Parafilm product was developed for histology and other “medical” applications. Parafilm essentially was an equal blend of a hydrocarbon wax and a polyolefin. It exhibits unusual elongation properties and at 70°F, it can be stretched by more than 200% and will partially return to its original length. At 180 to 200°F, it softens sufficiently to make an adhesive bond between papers, cloths, etc. A white separation paper is used to keep one layer from sticking to another.
Supplied in a dispenser carton. Click here to purchase an acrylic dispenser designed to offer superior protection from the blade while in use. Safety is especially important as it features a super sharp blade for easy cutting. The sturdy, transparent acrylic housing allows monitoring of the film supply. Holds one or two 2” rolls or one 4” roll.
