Specs & features.
Parafilm is a semi-transparent, odorless, and colorless sheet material composed of a proprietary blend of waxes and polyolefins. It is supplied in rolls wound on a paper core, typically interleaved with a paper backing grid that helps technicians measure and cut exact square pieces. The film is unique because it contains no adhesive; instead, it is pressure-sensitive and self-sealing. When stretched to its physical limit, it adheres firmly to itself or to smooth glass and plastic laboratory surfaces, creating a waterproof and moisture-proof seal.

- Exceptional Elongation and Stretchability: Can be stretched up to 200% of its original length, allowing a small square to form a tight, form-fitting seal over large or irregularly shaped container openings.
- Self-Sealing and Adhesive-Free: Bonds entirely to itself when stretched and pressed, leaving no sticky adhesive residue on glassware or plastic tubes upon removal.
- High Moisture-Barrier Efficiency: Highly resistant to moisture vapor permeability, which prevents critical animal fluid samples from evaporating or dehydrating during prolonged refrigeration or incubation.
