The material is virgin wood pulp, with a weight specification of 38gsm - 40gsm. It complies with the GB 4806.8 standard and holds FDA (USA) or FSC (Forest Stewardship Council) certifications, along with BSCI factory audits. The bowl-shaped paper liners feature high edges (typically 4.5cm) that catch grease like a bowl, offering the best protection for the fryer body—perfect for "lazy" users. The 16cm size is suitable for mainstream 3-5L models. It features a double-sided food-grade silicone oil coating. When dry-burned in an air fryer at 200°C for 10 minutes, there is no charring, smoking, or unusual odor. When water or oil is dropped on the surface, there is no penetration within 15 minutes.
