Smell Proof Mylar Bags
Custom smell proof mylar bags with multi-layer aluminum foil barrier that blocks 99.9% of volatile organic compounds. Perfect for cannabis, coffee, spices, and any product where odor containment is critical. Full-color custom printing from 500 units with child-resistant options.
How Smell Proof Mylar Bags Work
Each layer in our multi-layer laminate serves a specific barrier function. The aluminum foil layer is what makes mylar bags truly smell proof.
Outer PET Film
12 µm
Print surface, puncture resistance, structural integrity
Aluminum Foil
7-9 µm
Primary odor barrier — blocks 99.9% of volatile organic compounds (VOCs)
PE/CPP Sealant
50-100 µm
Heat-sealable inner layer with additional barrier properties
Optional: Activated Carbon
Variable
Absorbs residual odor molecules for maximum smell proofing

FDA compliantSmell Proof Mylar Bags FAQ
What makes mylar bags smell proof?
The aluminum foil layer in mylar bags creates an impenetrable barrier against volatile organic compounds (VOCs) — the molecules responsible for odor. Standard PET/Aluminum/PE laminate blocks 99.9% of odor transmission. For maximum smell proofing, activated carbon lining can be added to absorb any residual molecules.
Are smell proof mylar bags legal for cannabis?
Yes. Smell proof mylar bags with child-resistant closures meet compliance requirements in all legal cannabis states. Cubit's CR smell proof bags are ASTM D3475 certified and include compliance certificates. Many states specifically require opaque, child-resistant, odor-proof packaging for cannabis products.
How long do smell proof mylar bags keep odor in?
Properly sealed aluminum-foil mylar bags contain odor indefinitely — the aluminum barrier does not degrade over time. As long as the heat seal is intact, the odor barrier remains effective. Resealable zipper bags maintain smell proofing for 12-36+ months with regular opening and closing.
Can I get custom printed smell proof bags?
Absolutely. All Cubit smell proof mylar bags include full-color CMYK printing, Pantone matching, and premium finishes (matte, gloss, spot UV, foil stamping). The odor barrier properties are in the base film structure, so printing does not affect smell proofing at all.
What's the difference between smell proof and odor resistant?
'Odor resistant' typically refers to bags that reduce odor by 50-80% — often single-layer plastic. 'Smell proof' means the bag blocks 99.9%+ of volatile compounds, which requires an aluminum foil barrier layer. Cubit's mylar bags are fully smell proof due to the aluminum foil barrier.
What is the MOQ for custom smell proof mylar bags?
Custom printed smell proof mylar bags start at 500 units. Child-resistant smell proof bags also start at 500 units with ASTM D3475 certification included. Pricing starts at $0.15/bag depending on size and features.
