Every custom stand-up pouch we print is built from a three-layer polyester laminate: print-receptive PET outer, metallized MET-PET middle for the barrier, food-safe sealant inner that forms an airtight seam under our heat-bar press. The metallized middle layer is what separates a Mylar pouch from a standard poly bag — it's a physical vapor and oxygen block, not a coating.
Measured barrier performance on our standard metallized film: OTR below 0.1 cc/100 in²/day, MVTR below 0.02 g/100 in²/day. That's the same order of magnitude as a sealed glass jar. Recyclable PE-PE and PCR film constructions are available for brands with sustainability commitments.
