In the United Kingdom, Rexam High Performance Flexibles is using an on-line scanning system from NDC Infrared Engineering to measure the consistency of coating weights.
Rexam has reduced scrap and boosted quality, according to NDC of Irwindale, Calif.
The Rexam unit in Thetford, England, makes flexible packaging materials for food and drinks, such as potato chips, concentrated orange juice and wine. Two infrared gauges work on different lamination lines, scanning continuously across the width of the web.
Before Rexam installed the NDC gauges, the coating weight had to be checked by manual sampling several times a day.
