Oxidized Starch for Paper & Board Industry
KAGSTAR | SEVAGRAM EXCIPIENTS
KAGSTAR is a specially developed oxidized starch designed to meet the evolving requirements of the paper and board industry, particularly for surface sizing and coating of high-quality paper. Manufactured by Sevagram Excipients, KAGSTAR represents a balanced combination of strength enhancement, controlled viscosity, fast setting, and superior surface properties that modern paper machines demand.
As a leading producer of speciality and modified starches, Sevagram Excipients has developed KAGSTAR to align seamlessly with its established portfolio of white dextrin products for paper and board applications. Together, KAGSTAR (oxidized starch) and KAGDEXT-W (white dextrin) offer paper manufacturers a comprehensive solution for surface sizing, coating, and print performance optimization across diverse paper grades.
Oxidized Starch in Paper Manufacturing
Native starch, due to its long polymer chains and natural molecular structure, is often unsuitable for direct use in paper sizing and coating. It tends to exhibit excessive viscosity, poor flow characteristics, and inconsistent film formation under high-speed machine conditions.
Oxidized starch, such as KAGSTAR, is produced through a controlled chemical modification process that partially depolymerizes starch molecules and introduces functional groups. This modification results in:
- Controlled and stable viscosity
- Improved film-forming ability
- Enhanced penetration into paper fibers
- Better surface bonding and strength development
KAGSTAR has been engineered specifically to overcome the limitations of native starch while delivering consistent, reproducible performance in surface sizing and coating operations
Product Overview – KAGSTAR (Oxidized Starch)
KAGSTAR is a white, fine, free-flowing oxidized starch powder developed for paper mills producing printing paper, writing paper, packaging paper, and specialty paper grades. It is optimized for surface sizing applications where smoothness, strength, and printability are critical quality parameters.
This product is insoluble in cold water and forms stable, uniform solutions upon proper cooking, ensuring excellent runnability and compatibility with modern paper machine sizing presses.
Key Features of KAGSTAR Oxidized Starch
KAGSTAR delivers a broad range of functional benefits that directly translate into improved paper quality and production efficiency:
- Enhanced paper strength
Improves surface strength, stiffness, and resistance to picking during printing operations. - Faster setting time
Enables rapid film formation and drying, supporting higher machine speeds and better productivity. - Superior smoothness
Produces a uniform, well-leveled surface ideal for premium printing and coating applications. - Excellent printability
Improves ink holdout, reduces ink spread, and enhances print sharpness and color definition. - High solution stability
Maintains consistent viscosity with excellent flow and spread properties, minimizing process fluctuations. - Improved oil absorbency
Supports better ink receptivity, particularly in offset and flexographic printing processes. - Fine white powder form
Ensures easy handling, dosing accuracy, and uniform dispersion.
Applications of KAGSTAR in the Paper & Board Industry
KAGSTAR is primarily used for surface sizing and coating of high-quality paper, where performance consistency and surface properties are critical.
Surface Sizing
In surface sizing, KAGSTAR penetrates the paper surface evenly, reinforcing fiber bonding and enhancing surface strength. This reduces dusting, linting, and picking during printing, while also improving resistance to moisture penetration.
Paper Coating Support
When used as part of coating formulations, KAGSTAR contributes to film integrity, surface smoothness, and coating adhesion. Its controlled viscosity allows it to blend effectively with pigments and other binders.
Printing & Writing Papers
Improves print clarity, smoothness, and ink control for offset, gravure, and digital printing grades.
Packaging & Board Grades
Enhances surface strength and stiffness of paperboard, supporting better converting performance and print appearance.
