Paper mill wet end process

Wet End Additives

Building internal fiber-to-fiber bonding strength at the source for higher recycling rates and superior board quality.

Native Tapioca StarchBurst Factor +

The primary internal strength additive. When added to the pulp furnish, it bonds to fibers during pressing and drying, dramatically improving Burst Factor (BF) and tensile strength in recycled paper boards.

Burst Factor Improvement: Fills micro-voids between fibers, increasing inter-fiber hydrogen bonding — key for Kraft and Duplex boards.
Recycled Pulp Reinforcement: Essential for mills running 70-100% recycled fiber where natural bonding potential is depleted.
Cost-Effective: Locally sourced and processed — significantly cheaper than imported wet-end starches with equivalent performance.
Cationic StarchRetention Aid

Positively charged starch that electrostatically bonds to negatively charged fibers, fillers, and fines. Acts as an internal retention aid, reducing loss of expensive fillers to the white water loop.

Filler Retention: Retains calcium carbonate and kaolin clay fillers — directly reducing raw material costs per ton.
Drainage Improvement: Flocculates fines and filler, speeding up drainage on the wire and reducing drying energy.
Strength Boost: Dual benefit: retention aid AND strength additive in a single product.
Spray StarchPly Bonding

Applied between plies during the board-making process to bond individual layers. Critical for multi-ply Duplex and Triplex boards where ply delamination during converting is a major defect.

Ply Bond Strength: Creates a permanent fiber-tear bond between layers — boards will tear before the ply separates.
Flatness: Uniform application ensures even moisture distribution, preventing board warping during drying.
Converting-Ready: High bond strength allows aggressive die-cutting and folding without delamination.
Paper surface sizing process

Surface Sizing & Coating

Perfecting printability, ink holdout, and surface strength for writing, printing, and specialty papers.

Oxidized StarchSize Press

Chemically oxidized to achieve very low viscosity at high solid concentrations — penetrates the paper surface to form a dense, hydrophobic film that seals the sheet against ink feathering.

Ink Holdout: Forms a tough, uniform film that prevents ink from bleeding along fiber channels — essential for sharp, vibrant printing.
Cobb Value Reduction: Reduces water absorption (Cobb 60s value) dramatically — key for offset and inkjet printing papers.
Surface Strength: Binds loose surface fibers, preventing paper dusting and picking on high-speed printing presses.
Optical Brighteners (OBA)Whiteness

Fluorescent whitening agents that absorb UV light and re-emit it as visible blue light, increasing the perceived whiteness and brightness of the paper beyond 100% ISO.

Brightness Improvement: Can increase ISO brightness by 8-15 points — meeting customer expectations for premium writing and printing papers.
Cost-Effective Whitening: More economical than increasing TiO2 filler levels to achieve the same brightness target.
Stable Performance: Our OBA grades are stable in the starch cook and size press conditions.
Sizing ChemicalsWater Resistance

Alkyl Ketene Dimer (AKD) and Alkenyl Succinic Anhydride (ASA) internal sizing agents that react with cellulose fibers to create a permanent hydrophobic barrier within the sheet.

Permanent Sizing: Covalent bond with cellulose ensures sizing is not washed out in high humidity or wet-strength applications.
Neutral pH Operation: Our AKD grades work at neutral to alkaline pH, compatible with Precipitated Calcium Carbonate (PCC) filling.
Industrial water treatment

Process Aids & Water Treatment

Maintaining machine runnability, white water cleanliness, and efficient effluent treatment.

Biocides & Slime ControlMachine Runnability

Microbiological contamination in the white water loop creates slime deposits that cause sheet breaks, holes, and odor. Our oxidative and non-oxidative biocides keep the system clean.

Sheet Break Prevention: Slime deposits on rolls and felts cause sheet breaks — the single largest cause of production downtime in paper mills.
Odor Elimination: Sulfate-reducing bacteria create H2S odor. Biocide treatment eliminates this issue in recycled paper operations.
Felt & Wire Protection: Prevents biological fouling of expensive paper machine clothing.
DefoamersFoam Control

Silicone and mineral oil-based defoamers that instantly collapse foam in the headbox, saveall, and stock preparation — preventing sheet quality defects and overflow losses.

Headbox Foam: Foam in the headbox creates air bubbles in the sheet — visible as pinholes and weak spots.
Saveall Efficiency: Foam prevents proper fiber recovery in the saveall, increasing raw material loss.
Stock Preparation: Controls foam in pulpers and screens, improving capacity and reducing spillage.
Coagulants & FlocculantsETP

Inorganic coagulants and polyelectrolyte flocculants for efficient clarification of raw process water and effluent treatment plant (ETP) operation.

Fiber Recovery: Coagulate fine fiber and filler particles from white water for recovery and reuse — reducing raw material consumption.
ETP Compliance: Ensure treated effluent meets TNPCB/CPCB discharge standards for COD, BOD, and TSS.
Sludge Dewatering: Flocculants improve sludge cake dryness, reducing disposal costs.
FAQ

Frequently Asked Questions

Answers to the questions our clients ask most.

Q

What is the difference between Oxidized and Native Starch for paper?

A

Oxidized starch has a much lower viscosity at the same solid concentration, allowing deeper penetration into the paper surface at the size press. Native starch has higher viscosity and is used for internal wet-end strength addition. Both are critical — they serve different functions in the mill.

Q

Can your starches be used with 100% recycled fiber?

A

Yes, in fact our Native Tapioca Starch was specifically optimized for high-recycled-content furnishes. Recycled fibers have lower bonding potential, and our starch compensates by building the fiber network.

Q

What is the shelf life of Bleaching Powder / Sodium Hypochlorite?

A

These are reactive oxidizing agents. Bleaching Powder should be used within 3-4 months. Sodium Hypochlorite in liquid form degrades faster — within 1-2 months. We recommend ordering in quantities matched to your monthly consumption.

Q

Do you provide on-site technical support for dosage optimization?

A

Yes. Our mill technologists visit customer sites to run trials, optimize dosage levels, and measure performance improvements. This service is included for customers with supply contracts.
