BRAND Seal-R-film Closure film

The BRAND Seal-R-film is an elastic sealing film that can be stretched to three times its length. The film conforms to irregular shapes without wrinkles and adheres securely. As a result, the polymer film provides an airtight cover for laboratory glassware and Petri dishes. Seal-R-film is chemical resistant and prevents drying, oxidation and contamination of samples and liquids. The stretch film can be cut to size sparingly and each roll is batch-labeled for complete traceability.
