Parafilm

Universal, semi-transparent, highly elastic film designed for airtight and moisture
proof sealing and many other manual applications. The film can be stretched up to
200% and forms a completely tight seal even with irregular shapes and areas.
‒Resistant to polar substances such as saline solutions, inorganic acids and alkalis
for up to 48 hours
‒Effective temperature range −45 to +50 °C (melting point ca. +60 °C)
‒Non toxic, free of plasticizers
