Behind the Scenes: The Chemistry Behind Silicone-Coated Baking Paper

To most people, silicone-coated baking paper is just a simple non-stick liner. But for commercial bakeries, food processors, and international packaging buyers, this seemingly humble sheet represents a perfect balance of chemistry, performance, and food safety.

На сайте Runjia New Materials, we specialize in manufacturing high-performance silicone-coated baking paper for global foodservice and retail clients. Backed by FDA, EU, and BRC certifications, our products are trusted in over 30 countries. In this article, we unpack the science behind this everyday kitchen essential—and what makes Runjia’s solution stand out.

🧪 What Exactly Is Silicone-Coated Baking Paper?

Silicone-coated baking paper starts with a virgin pulp base sheet, which is then coated with a thin, uniform layer of food-grade silicone. The coating can be applied on one side (1S) or both sides (2S), depending on the intended use.

Key properties:

• Non-stick: Prevents food from sticking—no oil or spray needed
• Heat-resistant: Withstands oven temperatures up to 230°C (446°F)
• Greaseproof: Resists oil and moisture penetration
• Compostable base: When unbleached, PFAS-free, and plastic-free

Whether you’re baking croissants in an industrial oven or packaging frozen foods, silicone-coated baking paper ensures clean release and consistent performance.

🔬 The Chemistry: How Silicone Works

At the molecular level, the silicone used in baking paper is typically made from polydimethylsiloxane (PDMS)—a highly stable, food-safe polymer. During the manufacturing process, PDMS is cross-linked using heat and a catalyst (such as platinum or peroxide) to form a durable, flexible, and inert layer bonded to the paper.

Why this matters:

• Inert & food-safe: Won’t react with acids, oils, or moisture
• Low surface energy: Prevents sticking even with sticky doughs
• Gas permeability: Allows steam release for crisp baking
• Thermal stability: Maintains properties under high heat

Unlike cheaper coatings that may degrade or leach chemicals, Runjia uses solvent-free, odorless, FDA- and EU-compliant silicone formulations, ensuring safety and durability.

🛡️ Food Safety Certifications You Can Trust

With growing consumer and regulatory scrutiny, compliance isn’t optional—it’s essential. At Runjia, every roll or sheet of silicone-coated baking paper comes with:

✅ PFAS-free guarantee
✅ Chlorine-free base paper
✅ Certified under FDA 21 CFR, EU 1935/2004, BRC, and ISO9001
✅ Migration testing и COA (Certificate of Analysis) for every batch

This gives our B2B partners—whether retailers or food processors—full traceability and peace of mind when facing audits or customs inspections.
