KleenFlexTM from Heat and Control (heatandcontrol.com)is a thin flexible plastic that is metal detectable and FDA/USDA approved for contact with food. More durable than similar materials, KleenFlex is also resistant to many food industry chemicals. Its blue color contrasts with most foods and is easily identifiable. Use KleenFlex for product flow control skirts on weighers and conveyors, flexible partitions and shielding, and as an impact-dampening liner to protect delicate foods.  Seams can be smooth welded to eliminate unsanitary glued overlaps.
