Industrial Heavy Grease Grade 12 Greaseproof Paper 50g Maximum Oil Resistance
This 50 g/m² greaseproof paper achieves the highest Grade 12 oil resistance, capable of withstanding heavy industrial greases, oily mechanical parts, and extreme food applications (e.g., butter blocks, lard packaging). The fluorinated (PFAS) coating provides ultra‑low surface energy (≤25 mN/m) and temperature resistance up to 220°C. Note: Restricted for direct food contact in some regions; ideal for non‑food industrial uses or where regulations permit.

Process Introduction
Base paper from 80% softwood pulp, beaten to 85°SR. After conventional forming, pressing, and drying, a fluorinated coating (PFOS/PFOA‑free variants available) is applied via gravure roller to achieve a 1‑2 g/m² thin film. The coating is cured at 150‑180°C. The paper exhibits excellent chemical resistance and non‑stick properties.
Applications & Advantages by Category
-
Industrial Greaseproof Liners – Protects machinery parts from heavy lubricants.
-
High‑Temperature Baking – Industrial ovens up to 220°C; for commercial bakeries.
-
Butter Blocks & Lard Wrapping – For bulk food industry (where PFAS permitted).
-
Non‑Stick Release Liners – For adhesive tapes and high‑oil substrates.
Why Choose This Paper – 50g Grade 12 is the ultimate barrier for the most challenging oil/grease conditions, unmatched in performance but with regulatory considerations.
