Custom Gram Weight Butter Paper 50‑200g Tailored for Specialty Applications
For applications that fall outside standard grades, custom gram weight butter paper is available from 50 g/m² to 200 g/m² (and beyond upon request). Whether you need 55g for ultra‑light overlays, 85g for a specific printing press, or 180g for industrial separators, our flexible production can match your exact specification. Each custom batch follows GB/T 1468‑2011 quality standards, with full control over transparency, tearing resistance, and smoothness. Sizes can be sheet (e.g., 880*1230 mm) or roll (custom width 450‑914 mm).
| Parameter | Unit | Custom Range (50‑200g) |
|---|---|---|
| Basis Weight | g/m² | 50‑200 (tolerance ±5%) |
| Transparency | % | 70 (at 50g) down to 53 (at 200g) |
| Tearing Resistance | mN | 160 (50g) up to 600 (200g) |
| Smoothness (Bekk) | s | 32 (50g) down to 4 (200g) |
| Stretch MD / CD | % | 3.0‑4.5 / 12.0‑15.0 |
| Sizing Degree | mm | ≥1.5 |
| Moisture | % | 7.0±1.0 |
Custom grammage is achieved by adjusting the refining degree, web formation speed, and calendering pressure. For lower weights (50‑70g), beating degree is precisely controlled to maintain transparency without over‑fibrillation. For higher weights (130‑200g), extended beating and slower machine speeds ensure uniform formation. Surface sizing can be tailored to meet specific ink, water, or oil resistance requirements. Finished product is tested for all core parameters per GB/T 1468‑2011.
