Enzymatic Paper De-inking Agent
The Enzymatic Paper De‑inking Agent is a compound enzyme preparation containing cellulase and hemicellulase activities. It is formulated to break down ink bonds and surface residues on recycled fiber pulp, improving brightness and cleanliness. The preparation is supplied as a liquid concentrate designed for dilution into pulp processing streams. Supplier information indicates it is intended for large‑scale paper recycling operations.
Typical enzyme activity for cellulase in such agents ranges from 800 to 1 200 IU g⁻¹, while hemicellulase activity is usually 400‑600 IU g⁻¹. The optimal pH for de‑inking lies between 5.5 and 7.0, and the temperature optimum is 45‑55 °C, matching standard pulp‑washing conditions. Standard dosage recommendations are 0.5‑2 % of the dry pulp weight, which can raise sheet brightness by several ISO units. The product’s solids content is typically 15‑20 % on a dry basis, allowing flexible dilution.
Paper mills and recycling facilities use the agent to reduce chemical consumption and achieve higher‑quality recycled paper. Buyers often require bulk packaging such as 25 kg drums or 200 kg barrels, with flexible bulk options for larger volumes. The listing does not state minimum order quantities or lead times, so these details must be confirmed with the supplier. Prospective importers should also verify any environmental compliance certificates before finalising a contract.

Sourcing Enzymatic Paper De-inking Agent from Sino Bio-tech United Co., Ltd. - China Import Guide
Prior to ordering, ask the supplier for a recent batch certificate of analysis, including enzyme activity values, pH, and solids content. Request any environmental or safety certifications that demonstrate compliance with local recycling regulations and confirm that the product meets your quality standards.
Shipping originates from Shenzhen, China, typically via the Yantian or Shekou ports. Importers should agree on Incoterms such as CIF or FOB and verify the expected lead time, which is usually several weeks after order confirmation. Payment is commonly made by T/T, though other terms can be negotiated directly with the supplier.
After receipt, arrange an independent laboratory test to confirm enzyme activity, pH and moisture levels. Obtain the material safety data sheet and any batch‑specific analysis reports. Conduct a pilot trial on a small pulp batch to observe brightness gain before scaling up the full production run.
