What Are Mylar Bags?
Mylar bags are durable, flexible packaging pouches made from multiple layers of food-grade films — typically a polyester (Mylar®) layer.
A outer layer can carry print and support the pack surface(matte/glossy), a middle layer can introduce either a functional barrier or an aesthetic visual effect,a inner layer is designed to ensure direct product contact and facilitate reliable heat sealing.
In daily use, buyers call many shiny or opaque pouches “Mylar bags.” Some use this name for high-barrier packs too. This multi-layer construction creates an airtight, light-blocking, and moisture-resistant barrier that keeps contents fresh and protected for long periods.
