Paper Industry
There are two primary uses of dextrin in the paper industry that are of great importance. It is added
to paper during the sizing process to increase its strength and general quality. A size press is used to
size paper in order to improve its look, eliminate problems with ink bleedthrough, produce a smooth
and sturdy writing or printing surface, stop surface fiber picking, and get the sheet ready for coating.
Furthermore, corn starch is an essential adhesive in colored coatings for paper and paperboard.
Improving the paper's printability and general aesthetic appeal is the main goal of this coating
technique.
Adhesives containing dextrin find numerous uses in the production of packaging and paper
conversion. Paper bags, fiberboard cases, cartons, and envelopes all use it. Laminates, however, is a
key application. In this case, the slower drying time in conjunction with the strong bonding
performance is an affordable method of getting high-quality outcomes. Moreover, dextrin laminated
paper products are becoming more and more appealing to a recycling and composting-focused
consumer base due to its biodegradability.
Yellow dextrin is distinguished by its great adhesive qualities, low viscosity, and hygroscopic nature.
It is used in the foundry sector to improve the dry strength of cores by acting as a binder.
Interestingly, yellow dextrin is completely soluble in water, which makes it an important ingredient
in adhesives that dissolve in water, a thickening for printing, and a binder for paints.
Although maize starch has little effect on productivity in the paper and weaving sectors, it is
important to note that high-viscosity starch greatly increases fiber tensile strength, which in turn
improves the sizing procedure.
