Abstract

Siliconized papers are widely being used from food and packaging industry to pressure sensitive label industry and their use has increased considerably over the last decade. Surface and structural properties of the sheet influence the silicone hold out and release properties.

Surface sizing of the sheet is done prior to silicone coating. The objective of this research is to find their film forming capabilities, fluid hold out of various starches, and the effect of the various calendering process on the release properties was also studied.

No significant difference between the starch sources were observed, except for the modified com starch with alginate thickener. Increase in pick-up reduced the porosity of the sheet, giving better fluid hold out, and better release properties. Calendering affected the surface properties of the sheet, influencing the fluid hold out and release properties. Supercalendering produced sheets with better hold out and release properties compared to hot soft nip calendering.
