Super-Polyfoil resists tearing and punctures, provides sterility protection, is autoclave proof, and provides a chemically inert barrier. It may be used to cover vessels for autoclaving, incubating and for storing cell culture solutions, chemical solutions and laboratory implements. The polyester complies with the FDA regulations governing direct food contact applications. A blue thermoplastic polyester layer is laminated to 1 mil aluminum foil. Super-Polyfoil® blocks any possible pinholes that may develop in the aluminum foil. The polyester resists organic solvents and caustic agents. The laminate is easier to remove following autoclaving than plain aluminum foil which is subject to oxidation. Super-Polyfoil® is easily folded over objects containing openings and unlike aluminum foil, may be flattened without kinking. 100 sheets per package.
