Microwave Safe Greaseproof Paper 32g Grade 6 for Popcorn Bags and Reheating Liners

Specifically designed for microwave applications, this 32 g/m² greaseproof paper combines Grade 6 oil resistance with microwave‑safe performance. It does not spark, absorb excessive heat, or release harmful substances when microwaved, making it ideal for popcorn bags, reheating liners, and frozen meal trays. The fluorine‑free bio‑coating ensures clean release without sticking, while the balanced basis weight provides sufficient strength for automated bag forming.

Technical Specifications (QB/T 1014‑2010 & GB 4806.8‑2022)

Process Introduction
Base paper from 70% softwood + 30% hardwood, beaten to 76‑78°SR. Formed, pressed, pre‑dried. A specially formulated microwave‑stable modified starch coating (solid 12‑15%) is applied via metering rod at 1.5‑2.0 g/m². Post‑drying at 90‑110°C avoids over‑curing that could cause sparking. Soft calendering provides smoothness without excessive densification, preserving microwave compatibility. Finished paper tested for microwave safety (no arcing, no flame).
