Ideal for protecting samples and preventing contamination or evaporation—perfect for cleanroom environments and strict sanitation protocols. These pre-cut strips are sterilized using a Vapor Hydrogen Peroxide process, adding an extra layer of protection to Parafilm’s natural waterproof and moisture-resistant properties. Parafilm® M is a flexible, semi-transparent thermoplastic film designed for reliable sealing in laboratory, medical, and industrial environments. Engineered from a unique blend of waxes and polyolefins, Parafilm® stretches up to 200% of its original size, conforming tightly to irregular surfaces such as test tubes, beakers, petri dishes, and flasks. Each strip comes individually packaged in a sealed, lot-traceable pouch featuring a color sterilization indicator—ensuring both safety and convenience.
