Odor Barrier Bags Wholesale
A lot of thin plastic gets sold as odor-blocking. Real odor control takes multi-layer mylar with an aluminum barrier — which is the only kind we stock, at 19–45¢ per bag in 100-count packs.
How to Tell Real Mylar From Thin Film
Hold it to light: if you can see through it, it's single-layer film and odor walks right through. True mylar is opaque, holds a crease, and has real weight. Ours are triple-layer with resealable zips and tear notches — zip for daily use, heat-seal for airtight.
All packaging sold empty for lawful storage of food, herbs, coffee, and dry goods.
Frequently Asked Questions
What makes a bag odor barrier?
Multi-layer construction — PET film, aluminum layer, and PE liner fused together. The metal layer blocks odor molecules, light, and moisture. Single-layer plastic bags are not odor barrier no matter what the listing says.
Are your mylar bags actually odor barrier?
Yes — all our bags are true multi-layer mylar. Zipped shut they contain odor for everyday handling; heat-sealed they're fully airtight.
What sizes do odor barrier bags come in?
3.5g ($29.99/100ct), 1/2oz ($39.99/100ct), and 1oz ($44.99/100ct), in solid colors and printed designs.
How do I make them completely airtight?
Heat-seal the top edge with an iron or hair straightener — two seconds. See our sealing guide for the method.
