In papermaking production lines, starch is one of the most important natural polymer additives used in the largest quantities. It is primarily derived from plants such as corn, cassava, wheat, or potatoes. The function of paper making starch varies depending on the point of addition.

 

Addition Point For Paper Making Starch

 

1. Wire Part: It increases internal bond strength, resulting in tighter fiber-to-fiber bonding; enhances the paper’s dry strength and folding endurance; adjusts pulp viscosity; and facilitates white water separation.
2. Sizing Part: Enhances surface strength, preventing dusting and linting during printing. Improves water resistance and enhances ink writing and printing performance.
3. Corrugated Base Paper: strong adhesion, This is its core function, requiring exceptionally high initial tack and ultimate bond strength. It provides cushioning properties and influences the physical strength of the carton.
