Statistical prediction model for water vapor barrier of extrusion-coated paper

Abstract

Regression analysis was used to develop a prediction model for moisture barrier properties of extrusion-coated papers. Practically, water vapor transmission rates (WVTR ) of extrusion-coated papers are affected by three factors: coating weight (or squared mass) of a studied polymer, temperature, and moisture concentration of surroundings. The created model finds mathematical connections between WVTR and these variables covering the detected region of variables with a continuous WVTR estimation. By using mixing ratio as a variable of humidity, the model accurately estimates across the field of experiments and represents a fast and easy-to-use tool for the prediction of WVTR for extrusion-coated papers.
