Why Mylar Bags Are the Industry Standard for Cannabis Packaging

Mylar (biaxially-oriented PET) multi-layer films deliver the barrier performance cannabis demands: oxygen transmission rates below 0.1 cc/m²/day, moisture vapor transmission under 0.05 g/m²/day, and terpene aroma retention that keeps your product fresh from cure to consumer. Every Lekas bag ships with documented CR (child-resistant) certification and ASTM test reports.

We offer gravure printing (best for large runs, up to 10 colors, sharp detail) and digital printing (best for small runs, fast turnaround, no plate fees). Finishes include glossy, matte, soft-touch, metallic foil, and spot UV. We can match any Pantone color and print CMYK full-color designs with gradients and photographic images.
