Why Choose Our Mylar Bags
Custom Mylar Bags | Cannabis, CBD & Specialty Food Barrier Packaging
Mylar bags — technically metalized polyethylene terephthalate (PET) flexible pouches — provide one of the most effective moisture, oxygen, and light barrier systems available in flexible packaging, making them the preferred format for cannabis, CBD, specialty food, and any product where freshness preservation is critical. The metalized interior creates an almost impermeable barrier to water vapor, oxygen, and UV light — extending product shelf life dramatically compared to standard polyethylene or paper packaging.
Mylar Bag Applications
- Cannabis and Hemp Packaging: Child-resistant compliant mylar bags for cannabis flower, pre-rolls, edibles, and concentrates — the dominant format in legal cannabis markets
- CBD Product Packaging: Mylar pouches for CBD gummies, tincture sachets, and hemp-derived product packaging
- Coffee and Tea: Metalized barrier bags for specialty coffee and loose-leaf tea freshness preservation
- Specialty Food: Dried herbs, spices, protein powders, freeze-dried food, and moisture-sensitive snacks
- Seeds and Growing Supplies: Seed storage bags for gardening retail and survival food applications
Child-Resistant Configurations
Legal cannabis markets in California, Colorado, Nevada, and most adult-use states require child-resistant (CR) packaging for cannabis products. CR mylar bags use press-to-close zipper systems with child-resistant lock mechanisms certified to CPSC 16 CFR 1700.20. Exit bags — the CR bags required by California for cannabis retail — must be certified and carry the CR certification mark.
Why Mylar is the Cannabis Industry Standard
Legal cannabis dispensaries sell a product whose quality — terpene profile, potency, and aroma — degrades rapidly when exposed to oxygen, light, and moisture. Mylar bags address all three degradation factors: the metalized interior reflects UV light, blocks 99.9% of water vapor transmission, and reduces oxygen permeation to near zero when heat-sealed. For a product that sells at $10–$60 per gram, the packaging investment in a mylar bag represents a fraction of the product value while directly protecting the quality that justifies the premium price point.
Cannabis Exit Bag Requirements
California's Bureau of Cannabis Control requires that all cannabis purchases leave dispensaries in child-resistant exit bags — outer CR bags that contain the child-resistant primary packaging. Exit bags must carry the CR certification mark indicating CPSC 16 CFR 1700.20 compliance. We produce certified CR exit bags in standard dispensary sizes with custom branding options for dispensaries that use exit bags as brand touchpoints with their customers.

Mylar Bags in Portland — FAQs
Are mylar bags child-resistant?
Standard mylar bags with press-to-close zippers are not child-resistant. Child-resistant mylar bags use CR-certified zipper systems with lock mechanisms that require simultaneous compression and sliding to open — certified to CPSC 16 CFR 1700.20. Cannabis products in legal markets require CR mylar bags for compliance; we produce both CR and standard zipper configurations.
Can mylar bags be printed with CMYK color?
Yes. Mylar bags are printed using rotogravure or digital printing on the outer film surface before lamination. Full CMYK color with Pantone color matching is available, along with matte and gloss lamination, spot UV, and metallic ink accents. The metalized inner surface remains unprinted.
What size mylar bags do you produce?
We produce mylar bags in standard cannabis retail sizes: 1g, 3.5g (eighth), 7g (quarter), 14g (half), and 28g (ounce). Food and specialty product sizes range from 50g to 1kg. Custom dimensions are available outside standard sizes.
Are mylar bags resealable?
Yes. Mylar bags with press-to-close or slide-to-close zipper systems are resealable after initial opening. For cannabis products, the heat-sealed top provides tamper evidence on first open; the zipper maintains freshness for repeated access after opening.
