Latex Replacement by Starch - Modern Starch Technology Offers Possibility to Save Costs and Improve Quality at the same Time

摘要

Cooking a suitable starch together with ultrafiltered coating colour allows to maximise coating solids while using starch in the formula. This will 1. improve key paper properties 2. save drying energy/optimise drying profile/increase productivity Increasing the starch proportion in the high solids precoating formulation to 50% with simultaneousreduction of the total binder level from 16 to 14 parts improves 1. printed gloss at maintained gloss 2. stiffness 3. mottling 4. overall printability without negative effect on 1. surface strength 2. cracking in the fold.
