Paper applications

Surface sizing

Surface sizing of paper refers to the application of starch by means of a size press or film press. With increased speeds and energy saving requirements demanding higher application solids, this basic technology has developed into a sophisticated and demanding application. Precise run ability and excellent paper strength are a must for a successful starch in this field of application.

Sized papers show a considerably higher strength. This is, for instance, important for liner and corrugated media, but also for other packaging papers as well as for graphic papers. For tensile strength increase, penetration of the size into the paper is desired.
