Parafilm

Parafilm or laboratory sealing film is waterproof, stretchable, moldable, colorless, and self-adhesive. It is a versatile protective film that provides a moisture barrier for culture media while still allowing gas permeability. It is popular in the laboratory due to its moldability, offering flexibility to seal various objects and devices with irregular surfaces and openings. In a less known but common field, it is widely used for biological freshly cut products.
