Paper & Converting

Paper and converting products impact our everyday lives. Paper, film, foil, metal, textile, nonwovens and other material webs are laminated, coated, and treated in a variety of manners to create intermediate or final products. These web materials are used in flexible packaging, tapes, cans, labels, tags, wraps and many other consumer and industrial products. Measuring moisture ensures a flat usable product and reduces energy costs. Measuring coat weight, adhesive thickness or lacquer reduces costs associated with consumption and insures uniform quality.

Near Infrared (NIR) measurements provide an economical alternative to highly-regulated nuclear gauging. NIR transmitters are easy-to-install, calibrate and maintain, with extremely low cost of operation in comparison to other technologies such as ultrasound, microwave and time-of-flight. On-line measurement of coat weight and moisture speeds startup, reduces energy costs and scrap, and improves quality control while allowing for roll-to-roll or customer-run data archiving. Process Sensors Corporation (PSC) offers fixed point transmitters and Cross Direction Web Profile Systems. 

With worldwide sales and support offices, PSC assists on projects from initial scope and estimation of potential ROI to installation and integration of your system with responsive support after the sale.

Featured Applications

Moisture and Coatings on Paper Webs

Moisture monitoring and control of paper webs reduces edge curl, speeds start up, increases production output and reduces scrap.

Hot Melt Adhesive Coating Thickness

Proper hot melt adhesive coating thickness reduces raw materials expenses and ensures optimal bond strength.

Water-based Adhesive Thickness

NIR fixed and scanning sensors enable measurement and control of water-based adhesives for rapid identification of out of spec product.

Wax Coatings Converting Measurement

Protect paper cups and plates, corrugated boxes and other applications from degredation due to humidity with polyethylene and polypropylene waxes for low cost and high performance.   

Extrusion Cross Directional Hot Melt Die Bolt Coatings

High viscosity, hot melt Pressure Sensitive Adhesives (PSAs) are often applied to substrates via die bolt coaters in tape manufacturing, with die bolt zones measured across the web to minimize interactions, streaks and voids.

Measuring BOPP Films

BOPP films coated with acrylic, PVDC, or other coatings for moisture, odor and other film barriers can be measured with NIR on the wet end to optimize coat weight across the web profile.
