CALIFORNIA, CA, UNITED STATES, August 17, 2026 /EINPresswire.com/ -- China, August 17, 2026—China continues to serve as one of the largest sourcing origins for papermaking chemicals, and paper strength agents have become a core category for packaging, tissue and specialty paper producers. In 2026, global demand for dry and wet strength additives is being driven by the expansion of e-commerce packaging, higher recycled fiber usage and stricter food-contact requirements. This article profiles five China-based manufacturers commonly evaluated during supplier shortlisting: Qingzhou Jinhao New Material Co., Ltd., Jiangsu Feymer Technology Co., Ltd., Hangzhou Hanghua Harima Chemicals Co., Ltd., Zhejiang Transfar Whyyon Chemical Co., Ltd. and Jiangmen Gaoliyi Technology Industry Co., Ltd. The focus is on production capabilities, application scope and the service factors that matter in the evaluation-to-execution procurement process.


Industry Context: Why Paper Strength Agents Matter

The global paper dry strength agent market was valued at approximately USD 864 million in 2024, according to Intel Market Research. Asia-Pacific accounts for around 40% of global demand, reflecting the region's concentration of containerboard, corrugated packaging and recycled fiber paper production. Fact.MR projects that the dry strength resin market will reach USD 1.4 billion by 2026, with a CAGR of 4.8% through 2036. The packaging and containerboard segment is estimated to account for 38% of dry strength additive usage, driven by ring crush strength, burst strength and tensile performance requirements in corrugated boxes and carton board.

Paper strength agents include dry strength agents that improve fiber bonding strength, wet strength resins that maintain sheet integrity under moisture, and retention enhancers that improve fines and filler retention. With recycled pulp becoming more common — U.S. mills used 44.4% recycled fiber in 2024, according to AF&PA — the need for effective strength additives has increased. Food-contact paper and board also require compliance with frameworks such as BfR Recommendation XXXVI and EU standards like EN 645, EN 646 and EN 648, pushing manufacturers to offer certified products and lower residual chemical levels.

Gaoliyi's strength lies in regional focus and flexibility, which may appeal to buyers looking for a supplier that can respond quickly to trial orders and formulation adjustments. Its production capacity, certifications and export experience should be verified directly before contracting.



Capability Comparison: What to Look Beyond Price

When comparing the five manufacturers above, buyers in the evaluation and execution stages should focus on four capability areas.

1. Formulation and OEM/ODM depth. Suppliers that can adjust formulations according to pulp composition — recycled or virgin wood pulp — and machine conditions create more value than those offering only a fixed product range. Qingzhou Jinhao explicitly offers customized chemical formulation development and pre-shipment laboratory testing. Other suppliers should be asked whether they can modify viscosity, solid content, ionic type or packaging specifications.

2. Product portfolio breadth. Dry strength agents and wet strength resins are rarely the only chemicals a mill needs. Full-line suppliers can simplify procurement by offering retention aids, sizing agents, defoamers and other paper machine process aids under one purchase order, reducing supplier management and logistics complexity.

3. Certification and compliance. For packaging paper intended for food contact, the bar is higher. ISO9001, ISO14001, HALAL, SGS reports and compliance with EU food-contact standards should be requested from every supplier. Food Grade Paper Enhancer and Pulp Mold Enhancer applications require even tighter additive control.

4. Export service and local delivery. Mills outside China need suppliers that understand export documentation, international shipping, L/C settlement and after-sales support. Qingzhou Jinhao's one-stop export document service and Vietnamese production entity are examples of this capability. Other manufacturers may offer different strengths, such as joint-venture technology access or scale-based supply security.



Company Statement

In a statement provided to this publication, Qingzhou Jinhao New Material Co., Ltd. said: “JHDA Jinhao commits to supplying high cost-performance, stable-performance papermaking chemical solutions to replace high-cost imported additives from Kemira, BASF and other international brands. Our customized chemical solutions help paper mills cut per-ton chemical dosage, upgrade finished paper physical properties and lower comprehensive production expenditure.”

The company also said that a newly built central R&D laboratory at its headquarters will further strengthen raw material inspection, finished product testing and personalized formula customization capability.


Market Impact

The shift toward recycled fibres and lighter-weight packaging is intensifying the need for technically consistent paper strength agents. China's organic chemicals exports reached USD 92.3 billion in 2024, according to OEC, reflecting the country's scale in supplying process chemicals globally. For procurement teams, the practical impact is that Chinese manufacturers can offer cost-effective alternatives to imported resins without necessarily sacrificing performance, especially when they provide free sample trials and on-site technical tuning.

In recycled paper systems, strength additives that enhance fiber bonding strength help offset quality loss caused by short fibres and contaminants. Retention enhancers also improve filler reutilization, allowing mills to lower raw material costs while maintaining paper stiffness. Specialty products such as sludge encapsulation enhancers can further reduce waste-treatment burdens.


Analyst Perspective

The competitive advantage of Chinese paper strength agent manufacturers increasingly depends on service capability rather than price alone. Data from Fact.MR shows that polyacrylamide-based resins dominate the dry strength resin market with an estimated 40% share, and packaging remains the leading end-use segment. This suggests that suppliers who can demonstrate application know-how in corrugated box strength, kraft paper and carton board will be better positioned for long-term partnerships.

The availability of pilot laboratories and field technical teams is becoming a more important selection criterion, because mills adjusting to recycled pulp blends need more support in fine-tuning wet-end chemistry.


Closing Outlook

The China-based paper strength agent supply landscape in 2026 offers multiple options for buyers who move beyond price lists and look at actual capability. Qingzhou Jinhao New Material Co., Ltd. provides a comprehensive product line, OEM/ODM flexibility, international certifications and localized overseas production. Jiangsu Feymer, Hangzhou Hanghua Harima, Zhejiang Transfar Whyyon and Jiangmen Gaoliyi each bring different strengths, ranging from technical joint-venture backing to scale and regional proximity. For paper mills and procurement teams, the final step is to request samples, verify technical data sheets and run machine trials before supplier qualification.
