Proven Gauging Solutions to Give You the Competitive Edge

NDC has supplied web gauging systems to the blown film industry for over 50 years. System solutions provide a fully functional web gauging platform for today’s competitive blown film market. For the commodity product market, NDC's Gamma Backscatter gauge measures the blown film thickness directly on the bubble, close to the die.

For multi-layer products, NDC offers a unique blown film system configuration -- using Beta, X-Ray, IR and Haze gauge technologies -- that measures the product on the layflat following the collapser. The significance of this approach is its ability to quickly determine the profile shape, the average web thickness and also critical product components such as the thickness of barrier layers like EVOH and Nylon. This advanced blown film system incorporates three key features that provide significant performance benefits compared to conventional blown film configurations which simply measure the thickness of the film on the bubble.

  • High-speed near infrared barrier component measurement
  • Double layflat separation algorithm (DLSA)
  • Automatic Profile Control (APC)

Unlike competitive capacitance gauges, NDC's gauges are insensitive to the film composition, ambient temperature and humidity, making them ideal for measuring the total thickness of products such as single-layer and basic multi-layer films.

With NDC's blown film solutions, manufacturers realize improve product quality, maximize product yield, boost process efficiencies and realize significant manufacturing savings.
