Detailed Production Process of Our Paper Cup Base Paper

Our paper cup base paper production follows a rigorous workflow:

1. Raw Material Preparation

● Wood Selection: Use certified coniferous and broad-leaved wood, debarked, chipped, and screened to remove impurities.

● Pulping:

● Chemical Pulping: Dissolve lignin with specialized chemicals in cooking pots for pure pulp.

● Mechanical Pulping: Grind wood chips into fibers to enhance flexibility, often blended with chemical pulp for balanced strength.

2. Pulp Treatment & Paper Formation

● Beating: Professional equipment fibrillates fibers to improve bonding, customizing paper strength and toughness as required.

● Blending: Add tailored additives (e.g., sizing agents) based on product specifications for targeted performance (e.g., oil resistance).

● Papermaking:

● Dehydration: Form wet paper sheets on a wire mesh, followed by pressing to remove excess water.

● Drying: Use controlled heat (hot air/steam) to reduce moisture content, ensuring final grammage and thickness.

● Calendaring: Smooth the surface for uniform quality and print readiness.

3. Quality Control & Customization

● Pre-Coating Inspection: Test key metrics (thickness, whiteness, stiffness) to meet client specs and food-grade standards.

● PE Lamination: Apply polyethylene coating to achieve water and oil resistance, ready for end-use in cups, bowls, etc.

4. Final Delivery & Client Use

● Packaging: Rolled or sheeted as per client needs, packaged hygienically for safe transport.

● Client Workflow: Upon receipt, clients can directly print, cut, form, and market finished products, ensuring efficiency and convenience.
