Gas permeation resistance
Tedlar® release films offer gas permeation resistance into and out of the sample bags, assuring sample integrity. Also, because it is chemically inert, it will not react with or alter the composition of the wide range of collected chemicals in your sample.
Tedlar® release films are rated for continuous use from -72°C to 107°C (-98°F to 225°F) and are referenced in many US EPA methods, including 3, 18 and 0040.
When used for gas sample bags, Tedlar® release films will prevent contamination and leaking and help ensure the integrity of your sample.
