Laboratory Film

Features and benefits

• Protect the integrity of research applications with a tight moisture-barrier that holds a strong seal and doesn’t release from glassware, despite off-gassing
• Reduce the risk of tampered data with a covering that is odorless, colorless and semi-transparent
• Prevents moisture and volume loss due to material composition and tight seal
• Flexible and self-sealing material allows it to cling around irregular shapes and surfaces
• Stretches more than 200% of original length
• Resistant up to 48 hours against many polar substances such as saline solutions, inorganic acids and alkaline solutions

Permeability

• Oxygen: (ASTM 1927-98) 150 cc/m² d at 23°C and 50% RH
• Carbon Dioxide: (Modulated IR Method) 1200 cc/m² d at 23°C and 0% RH
• Water Vapor: (ASTM F1249-01)

• Flat: 1 g/m² d at 38°C and 90% RH
• Creased: 1 g/m² d at 38°C and 90% R
