In the Industrial Category, Celplast received the Technical Award for its REFLECT-MET™ top-coated metallized PET, which is used in AstroShield material, a low emissivity product sold by Innovative Energy Inc., Lowell, Indiana, for applications requiring reflective insulation or a radiant barrier. Converted by Pregis Innovative Packaging Inc., Plymouth, Indiana, and used primarily in building construction and remodeling, the AstroShield options include REFLECT-MET™/bubble/bubble/Reflect-Met, Reflect-Met/white bubble or Reflect-Met/white bubble/white bubble. The coated metallized layer helps the lamination meet water vapor transmission, strength, thermal and fire performance requirements, while providing a brightness similar to foil. In fact, the REFLECT-MET™ layer meets reflective insulation standards for moisture corrosion resistance (ASTM D3310), vapor retarding (ASTM E-96), aged vapor retarding (ASTM C1258) and emissivity less than or equal to 0.05 (ASTM C1371). The coated metallized polyester also is significantly more machinable than thin-gauge foil because its resists the tear-outs and creasing that typically generate scrap rates ranging from 4% to 8% for foil laminations. Perhaps, most importantly, the REFLECT-MET™ metallized polyester meets pending changes to the ASTM E-84 flame test, which will render laminations using an unprotected foil layer unacceptable. Finally, the fiber-free lamination comes in easy-to-handle rolls, requires no custom installation tools, and eliminates the need for any special personal protection equipment.
Although insulation is a big market for metallized material, the judges concluded, “We haven’t seen anything like this with so many technical attributes.” The top coating is key because it protects the metallization. The judges also viewed the material as safer in a fire than foil laminations used for reflective insulation and appreciated its proactive compliance with pending standards for flame and smoke spread.
