Kraft paper lives or dies on strength. Converters test burst, tear, tensile and ring crush long before anyone looks at the surface, and a reel that falls short goes back to the mill.
Most kraft mills in North India run on recycled fibre or agro-residues, which are weaker than virgin wood pulp. That is where strength chemistry earns its place. Our dry strength resin and cationic starch help mills recover lost strength, and guar gum powder improves fibre bonding and formation. Together they let mills either meet specification more comfortably or bring basis weight down without failing tests.
What kraft mills buy from us
- Strength – D.S.R., cationic starch and maize starch for surface application.
- Sizing – fortified rosin with ferric alum for Cobb control, plus surface size chemicals for liner.
- Retention and drainage – retention aids and flocculants for save-alls.
- Clean running – stickies control for recycled furnish and SAPCO NDW / NXZ defoamers.
- Shade – Bismarck Brown, Auramine and Direct Black for consistent kraft colour.
We also supply press felts and dryer screens for kraft machines, so mills can source both chemicals and clothing from one place.
Send us your furnish, grade and current strength figures – we will recommend a programme to close the gap.
