Paper moisture measurements are critical throughout most stages of the paper making and converting process as manufacturers are constantly adjusting moisture to maintain the quality of their product. Additionally, online measurements of coating thickness are very important on webs during the manufacturing process allowing users to eliminate waste, reduce energy usage and produce quality products within specification 100% of the time.
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.
Types of coating applications:
Water Soluble Films
Wax Coating Water / Solvent
