Moisture in paper plays an important role in the printing and converting process as it can vary from 1-12% depending on the relative humidity and type of pulp and chemicals used. It is essential to control the moisture content of paper and keep it stable during the converting process as poor moisture control can have a negative effect resulting in curl, poor stability and out of specification product.
Measuring coat weights is also important factor during paper converting for the precise control of films, water based adhesives, resins and hot melt glue applications. Polyethylene, polypropylene and other coatings such as PVC can also be measured and controlled to a high degree of accuracy. The IR3000 helps control the re-moisturizing process, monitor any additions of adhesive coatings and detect coating defects.
