High Fold Resistance Pure Paper Back Strip 80g for Exercise Books and Notebooks

Designed for standard exercise books and softcover notebooks, this 80 g/m² pure paper back strip offers excellent fold resistance (≥50 times) and tensile strength (longitudinal ≥3 kN/m). Made from long‑fiber wood pulp paper, it ensures even glue absorption without bleed‑through. Available in white, beige, and custom colors, it reinforces the spine, prevents page detachment, and enhances the professional finish of bound books.

Pure paper back strips start with long‑fiber kraft paper rolls. The paper is surface‑cleaned and static‑eliminated, then coated on one or both sides with starch glue, PVA, or acrylic emulsion at 120‑180 g/m². It passes through a hot‑air drying tunnel at 80‑110°C to reduce moisture ≤8%. After cooling, the web is precisely slit into widths from 15 to 50 mm and rewound into 1000m rolls. Strict quality control ensures uniform glue distribution and high folding endurance.
