Custom Smell-Proof Mylar Bags
Custom printed smell-proof mylar bags with a foil or metallized barrier, tight seals and resealable or CR zippers.
About our bag
Custom Smell-Proof Mylar Bags made to order
Custom smell-proof mylar bags are built to keep strong aromas inside. A metallized or aluminum foil barrier, a quality zipper and wide heat seals work together to contain odor and protect the product from air and moisture.
What makes a bag smell-proof
Odor escapes through film that lets gas pass, through weak seals and through cheap zippers. Our smell-proof bags address all three with a high-barrier laminate, wide seals and a firm zipper, and they can be upgraded with a child-resistant closure.
Popular uses
- Cannabis and hemp flower

Sizes

Questions about Custom Smell-Proof Mylar Bags
Can I have a window on a smell-proof bag?
You can, but a clear window lowers the barrier. For maximum odor control we recommend an opaque bag.
How long do they stay smell-proof?
As long as the zipper is closed properly, the bag keeps odor in through normal use.
