Spray Starch for Paper & Board Industry
KAGSPRAY | SEVAGRAM EXCIPIENTS
KAGSPRAY is a specially developed spray-applied modified starch engineered for the paper and board industry, with a focused application in kraft paper and duplex board manufacturing. Designed to meet the evolving performance and efficiency demands of modern paper machines, KAGSPRAY delivers measurable improvements in ply bonding, stiffness, bursting strength, surface finish, and runnability, while simultaneously reducing linting and delamination issues.
At Sevagram Excipients, we specialize exclusively in industrial-grade modified starches for paper, board, textile, gypsum, and allied industries. KAGSPRAY aligns seamlessly with our paper and board product portfolio, offering a cost-effective, high-performance alternative to conventional native and pre-gelatinized starches used in surface and strength enhancement applications
What is Spray Starch?
Spray starch is a dry modified starch powder applied directly onto the paper or board surface through a controlled spraying system, typically using a metering pump. Unlike wet-end starches that often suffer from poor retention and inconsistent penetration, spray starch allows higher starch add-on levels without compromising retention efficiency.
KAGSPRAY has been formulated to overcome the limitations of native starches that tend to remain on the surface and fail to integrate effectively into the fiber matrix. Through controlled penetration and optimized gelatinization in the dryer section, KAGSPRAY ensures durable strength development and uniform board properties across production runs
KAGSPRAY from Sevagram Excipients
Paper and board manufacturers face constant challenges related to strength optimization, machine efficiency, raw material costs, and effluent load management. KAGSPRAY directly addresses these challenges through its tailored chemistry and application flexibility.
Key Performance Advantages
- Enhanced ply bonding in kraft paper and duplex board
- Improved bursting strength and stiffness, even at lower dosages
- Controlled starch penetration, enabling consistent quality
- Reduction in linting and board delamination
- Improved spring-back tendency, essential for packaging boards
- Superior surface finish, suitable for downstream converting and printing
- Cost-effective application compared to wet-end starch systems
- Lower BOD and COD levels in backwater due to efficient starch utilization
These advantages translate into higher productivity, improved paper machine runnability, and reduced operational variability, making KAGSPRAY a preferred choice for mills targeting quality upgradation without significant capital investment.
How KAGSPRAY Works in Paper & Board Manufacturing
KAGSPRAY starch particles are designed to be easily entrapped within paper fibers upon spraying. Once applied, the starch migrates into the sheet structure and undergoes gelatinization in the dryer section, forming strong inter-fiber and inter-ply bonds.
The controlled penetration mechanism ensures that starch does not merely sit on the surface but actively contributes to internal strength development. This is particularly critical in multi-ply duplex boards, where weak bonding often leads to delamination during conversion or end use.
By allowing higher starch application levels without retention loss, KAGSPRAY offers consistent performance across varying machine speeds and board grammages.
