Choosing a Paper Strength Agent Manufacturer: Certifications, Parameters, and Supply Checklist
How to Evaluate Paper Strength Agent Manufacturers for Paper Mills
JHDA JH-1699 Paper Tensile Strength Enhancer
A paper strength agent is a wet-end chemical used to increase fiber bonding strength, tensile strength, ring crush, burst and stiffness. For paper mills using recycled fiber, the right strength agent often determines whether the finished paper can meet box plant compression specifications, printing requirements or food-contact standards.
Qingzhou Jinhao New Material Co., Ltd., branded as JHDA, is a papermaking chemicals manufacturer founded in 2005 and located in Qingzhou City, Shandong Province, China. The company supplies dry strength agents, wet strength resin, tensile strength additives and related wet-end chemicals to paper mills in Asia, Africa and South America.
Why Paper Mills Need a Qualification Process
Three buying mistakes are common in papermaking chemical procurement. First, a manufacturer may have competitive prices but incomplete compliance documents, which creates risk during customs clearance or food-contact audits. Second, a product may work on virgin pulp but fail on recycled pulp because anionic trash, ash content and fiber quality vary. Third, after-sales support may stop after shipment, leaving the mill without dosing guidance or troubleshooting.
A paper mill should therefore qualify a paper strength agent manufacturer on four dimensions: certification, product parameters, customization capability and supply support.
Industry Background: Strength Additives Are Becoming More Important
Recycled fiber now plays a larger role in papermaking. The American Forest & Paper Association reports that recycled paper accounted for 44.4% of all fiber used at U.S. mills in 2024. Recycled fibers are shorter and have lower bonding potential than virgin fibers, so dry strength agents are often required to keep packaging paper strong.
Intel Market Research estimates the global paper dry strength agent market at approximately USD 864 million in 2024, with Asia-Pacific accounting for about 40% of the market. Fact.MR data also indicates that packaging and containerboard represent around 38% of dry strength additive consumption, and polyacrylamide-based products account for about 40% of dry strength resin types.
These trends explain why a paper strength agent manufacturer must be able to adapt to recycled pulp, high filler levels and high-speed paper machines.
What to Look for in a Paper Strength Agent Manufacturer
1. Certifications and Regulatory Compliance
Start with verifiable management system certificates. JHDA's production of papermaking additives is certified to ISO 9001:2015 quality management system standard with certificate no. 10423Q01592R1S, and to ISO 14001:2015 environmental management system standard with certificate no. 10423E01032R2S. The company also holds SGS product compliance test reports for packaging paper chemicals.
For Indonesia and other Halal-compliant markets, JHDA's dry strength agent, wet strength agent and paper tensile strength enhancer are covered by HALAL certificate no. 6637250000, issued by Shandong Halal Certification Service under MS1500:2019.

2. Product Parameters and Chemistry
Compare active content, solid content, ionic type, pH, viscosity, solubility and shelf life. A liquid amphoteric dry strength agent such as JH-D726 is different from a cationic powder such as JH-1699. The right choice depends on furnish, machine type and target paper properties.
3. Customization and Manufacturing Capability
JHDA provides OEM/ODM service, formulation customization, label production and packaging customization. The company has an MOQ of 1 MT and a production lead time of 4 work days. Its technical team can adjust formulas according to pulp composition, including recycled pulp and virgin wood pulp, and machine operating parameters.
4. Technical After-Sales and Export Support
On-site machine debugging is part of JHDA's service model. The company can help optimize Cobb water absorption, ring crush strength, bursting strength, brightness, fiber retention rate and overall paper machine runnability. Export documentation includes TDS, MSDS, certificate of origin, pre-shipment inspection report and dangerous goods transport certification. Typical quality control tests include particle size, appearance, solids, pH, viscosity and functional tests.

Step-by-Step Supplier Evaluation Process
- Define the furnish and target grade. Determine whether the mill runs OCC, mixed waste, virgin wood pulp or a blend. Identify whether the final paper needs ring crush, burst, tensile, stiffness, wet strength or food-contact compliance.
- Verify certificates. Ask for ISO certificates, food-contact test reports and market-specific certifications such as HALAL. Confirm the manufacturer name and certificate number.
- Compare technical data sheets. Check solid content, active content, ionic type, pH, viscosity, shelf life and recommended dosage. The best paper strength agent is the one that fits the mill's wet-end conditions.
- Run a lab or pilot trial. A trial sample should be tested on the actual pulp used by the mill. JHDA's pilot laboratory can support formulation testing and performance verification before bulk purchase.
- Check logistics and payment terms. Confirm MOQ, production lead time, export documents and payment methods. For international orders, JHDA offers T/T, sight L/C and DP payment options.
Common Use Cases for Paper Strength Agents
Recycled Linerboard and Corrugated Medium
JH-1699 is designed for OCC recycled pulp and corrugated medium. It acts as a ring crush strength agent and burst strength improver, helping mills reduce paper breaks and maintain box compression strength.
Kraft Paper, Testliner and Box Board
JH-D726 can be used as a tensile strength additive and paper stiffness reinforcer for kraft paper, testliner and box board. It is formulated to improve fiber bonding while remaining compatible with sizing agents and other wet-end chemicals.
Food-Grade Pulp Molding
JH-2219 and JH-1697 are suitable for food packaging pulp molds and food-grade pulp tableware. Both are designed for recycled pulp applications and do not contain formaldehyde.
Tissue, Paper Cup, Filter and Medical Paper
JH-1201 wet strength resin is intended for tissue paper, paper cup base paper, filter paper, medical disposable paper and recycled packaging paper. It provides wet and dry strength in wet-strength grades.
High-Filler Furnishes
For mills using calcium carbonate or talc to reduce cost, JHWB-1320 filler sludge encapsulant helps fix filler particles on fibers and compensates for strength loss, protecting tensile and ring crush while improving filler retention.
