CMP is a professional custom mylar bags manufacturer offering OEM & ODM services based in China. Our food-grade mylar pouches deliver excellent barrier protection against moisture, oxygen and light, with fully customizable sizes, materials and full-color printing.
Small & Large Batch Production To Fuel Your Brand Growth
Our digital printing/gravure printing works for small trial runs and large bulk orders. We deliver premium custom mylar bags with low MOQ and quick lead times to grow your brand.
Mylar bags are durable, flexible packaging pouches made from multiple layers of food-grade films — typically a polyester (Mylar®) layer.
An outer layer can carry print and support the pouch surface(matte/glossy), a middle layer can introduce either a functional barrier or an aesthetic visual effect,an 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.
