Tedlar sampling bags

Our Tedlar® Air Sampling Bags are made from the classic DuPont® film. The DuPont film is the industry standard and has a good stability for VOCs, sulfur compounds, carbon monoxide, carbon dioxide, methane, and sulfur hexafluoride. Our Tedlar sampling bags are made of 2mil Tedlar® PVF film. This film is tough, durable, and considered chemically inert to a wide range of compounds.

Physical and thermal properties Tedlar

Tedlar® PVF film is strong, flexible, and fatigueresistant. Its resistance to failure by flexing is outstanding. Tedlar® performs well in temperatures ranging from approximately –72 to 107°C (–98 to 225°F), with intermittent short-term peaking up to 204°C (400°F). Some physical and thermal properties of representative Tedlar® PVF films are summarized below.
