PARAfILM stretches up to 200% andclings evenaround irregularshapes and surfaces.The sealing film isfree of plasticizersand consistsprimarily of polyolefins and paraffin waxes. PARAfILM M is resistant up to 48 hours against many polar substances eg saline SOLUTIONons inorganic acids and alkaline SOLUTIONons.Protect the integrity of research applications with a tight moisture-barrier that holds a strong seal and doesnt release from glassware despite off-gassingReduce the risk of tampered data with a covering that is odorless colorless and semi-transparentPrevents moisture and volume loss due to material composition and tight sealflexible and self-sealing material allows it to cling around irregular shapes and surfacesStretches more than 200% of original lengthResistant up to 48 hours against many polar substances such as saline SOLUTIONons inorganic acids and alkaline SOLUTIONonsPermeabilityOxygen (ASTM 1927-98) 150 cc/mA² d at 23C and 50% RHCarbon Dioxide (Modulated IR Method) 1200
