Parafilm®
Flexible, waterproof, thermoplastic sheets are rolled and interwound with paper to stop adhering. Has almost no colour, is tasteless, odourless, and semi-transparent. Comes in about 0.005" thickness. Will seal firmly and rapidly to itself, covering culture tube or flask mouths in the bacteriological laboratory. Exceptional sealing for a Petri dish. Resistance to alcohol, air, other gases, moderately concentrated alkalies, and common acids is excellent. Stretches 200% at 70°F, and returns partially to its original size. At 180° to 200°F the Parafilm softens to form an adhesive bond between leathers, papers, cloths, etc. For easy cutting and measuring, the interleaving tissue is calibrated in 2" squares.
