Polyester Industrial Films

The unique combination of physical, thermal, chemical, and optical properties makes polyester films ideal for a wide range of industrial applications. Many times, the specifications of products being sold for industrial end uses are broader in terms of upper and lower allowable limits. This reality places even more emphasis on product “fitness for use”, which is the skill of matching the right product type to the performance requirements of a given industrial application. Tekra’s quality systems and programs work in connection with DuPont Teijin Films™, which provides lot-to-lot consistency you can rely on. Our customers benefit from the assurance of supply quality, product consistency, and continuity.
