This PPT provides a clear understanding of how cationic surface sizing significantly upgrades paper performance. Through the use of cationic surface sizing agents like cationic starch, a smoother and stronger surface is formed, allowing better ink interaction and superior print results. The presentation outlines key improvements such as enhanced surface strength, increased stiffness, improved water resistance, and minimized dusting. It also covers practical benefits for printing, packaging, and recycled paper applications. Designed for the paper and pulp industry, this presentation shows why cationic surface sizing is a smart, reliable, and sustainable method for producing high-quality paper.

How Cationic Surface Sizing Improves Paper Quality
HOW CATIONIC
SURFACE SIZING
PIMAPREORV QESU ALITY
A brief overview of how cationic surface
sizing, cationic surface sizing agents, and
cationic starch enhance paper
performance and printability.
WHAT IS
CATIONIC
• CSatUionRic FsuArfaCce Esi zing is a process
that applies a positively charged film
oSn IthZe IpNapeGr s?urface using a cationic
surface sizing agent like cationic
starch.
• This layer improves bonding, creates
a smooth surface, and enhances ink
interaction, making the paper
stronger and more print-friendly.
ROLE OF CATIONIC
STARCH
Cationic starch is the most widely
used cationic surface sizing agent.
Its positive charge helps it bond
strongly with cellulose fibers,
improving:
• Fiber-to-fiber strength
• Surface smoothness
• Ink holdout and print clarity
• Water resistance
KEY
Cationic surface sizing
significantly enhances paper IMPROVEMENTS IN
quality by:
PAPER QUALITY
• Increasing surface
strength and pick
resistance
• Reducing dusting and
linting
• Providing better print
sharpness
• Improving stiffness and
surface film formation
• Enhancing runnability in
high-speed printing
BENEFITS FOR
PRINTING &
UPsinAg Ca KcaAtioGnicI NsuGrface sizing agent
helps achieve:
• Crisp and bright printing results
• Reduced ink feathering and spreading
• Better performance in digital and
offset printing
• Stronger packaging papers with
improved durability
• Higher quality when using recycled
fibers
CONCLUSION
Cationic surface sizing, especially when
using cationic starch, delivers superior
paper quality through improved strength,
smoothness, and print performance.
It offers a cost-effective, sustainable
solution for modern paper mills producing
high-quality printing and packaging
grades.
