Composite Resin Coated Papers

Product Details:

SunPro® packaging paper was made by coating the base paper with the PLA solution, with two different concentrations. The comparison with the commercial packaging paper has shown that similar surface properties were obtained. The influence of coating on optical properties of paper is small, roughness and brightness decrease a little, opacity is higher, and color change is negligible. The analysis has shown that already lower concentrations of PLA solution enable uniform coating, which lowers permeability and gives good barrier properties to water.
