A smell proof mylar bag adds odor containment to the usual mylar barrier, which matters for aromatic products like cannabis, coffee, spices, and strong snacks. A multilayer foil laminate with a tight seal keeps aroma in and freshness protected, so the product does not announce itself in a bag, on a shelf, or in a mailbox.
Odor containment comes from the laminate and the closure working together. The foil layers block the escape of volatile aromatics while blocking light, oxygen, and moisture from getting in, and a heat seal or a tight resealable zipper keeps the seal intact. Add a child resistant closure for cannabis, a tear notch, and full color print. Opaque construction adds discretion for products that need it.
We make custom smell proof mylar bags in your size with no minimum order, so a brand can package aromatic products discreetly and freshly on a small run, at the best price. For cannabis, follow your state packaging, child resistance, and labeling rules, which are the brand's responsibility. Send us the product and fill weight and we will spec the bag.
