Role of substrate, polymer characteristics and additives

Abstract

The role of substrate, polymer characteristics, and additives in improving the surface roughness of paper or board, by a surface treatment was investigated. Hot calendering reduces the uptake of polymer during the coating operation, and improves to some extent the spreading of the polymer solution or dispersion on the surface. The polymer characteristics govern the barrier properties of the coatings, but these can be optimized by additives and by surface treatments such as corona discharge. The barrier against grease for poly(vinyl alcohol)-coated (PVA) substrates was enhanced with a partially hydrolyzed PVA-grade, when the substrate was hot-calendered.
