ABSTRACT
Silicone-treated release papers are widely used, from food and packaging to pressure-sensitive
labels. Due to the high cost of silicone, release papers are surface sized prior to application of
the silicone coating. Corn starch has been unrivaled as a surface starch because of its
advantageous cost/performance characteristics. However, paper companies are beginning to
evaluate other starches because performance, not cost, has become paramount in the
development of new products in the current, extremely competitive business environment. There
is already anecdotal evidence that starches other than corn may have advantages in certain
applications. However, there is no fundamental understanding of the reasons underlying the
improved performance characteristics of some starches over corn starch. The objective of this
research is to begin to understand the performance differences between various starches in
release papers. The sizing and silicone-holdout properties of papers surface sized with various
starches were studied to determine whether some starches have better performance
