Smell Proof Mylar Bags
The odour barrier comes from the laminate structure, which means it can be tested rather than assumed.
It is a property of the film, not the zipper, and customers judge the product by it. A pack that leaks aroma is losing condition and announcing its contents at the same time.

Every detail. Intentional.
A laminate property
Structure decides it, not the closure.
Worth testing, not assuming
It is measurable, so measure it.
Opacity where mandated
Metallised layers hide contents and block light.
Seal integrity matters equally
A perfect film with a weak seal still leaks.
Certified CR where required
Closure and film certified together.
Matte black is the register
The category's prevailing shelf look.
Built like architecture.
Every order of Smell Proof Mylar Bags is an engineered build, measured, dieline-cut and hand-wrapped to spec. Below is the standard build sheet.

Sizing & dieline.
Every Smell Proof Mylar Bags is made to your fill, not pulled off a shelf. A pouch is quoted width × length, plus the gusset that lets it stand. Tell us what goes inside and how much of it, and we return a measured spec, free, before you commit to anything.
A pouch is sized by what goes in it, not by outside dimensions. Give us the fill weight and, if you can, the bulk, since 500 g of granola needs far more bag than 500 g of powder.
We quote width × length, then the bottom gusset depth that sets the footprint. Three figures, and the gusset is the one most often left off.
Zipper or heat seal only, valve or no valve, window or full barrier. These change the film and the bag height, so they belong in the spec rather than added afterwards.
✦ Not sure of your size? Send us the product and we measure it and build the dieline.
Pricing & minimums.
We price Smell Proof Mylar Bags per specification rather than from a fixed list, because the same build in two different finishes can land at very different numbers. Below is what actually moves the price, so you can shape the spec before you request a quote.
The single biggest lever. Unit cost falls sharply as volume rises, because setup and tooling spread across more pieces.
Board weight and stock choice change both the raw material cost and the shipping weight of the finished run.
Foil, spot UV, embossing and soft-touch each add a pass on press. One or two lift the box; five compound the cost.
Full-bleed print inside and out costs more than a one-sided design on natural stock.
Foam, moulded pulp, velvet pillows, magnets and ribbon are priced per piece on top of the box itself.
Standard production is the base rate. Rush moves you up the production queue and carries a surcharge.

Questions, answered.
Everything you need to know about Smell Proof Mylar Bags.
The laminate structure, and specifically a genuine aluminium foil layer in the middle of it. Odour barrier is a property of the film, not of the closure. A metallised film is decent and cheaper, but it is measurably weaker on odour than real foil. PET, aluminium foil and PE is the only structure that gets close to a true barrier.
Because it is a film property it can be tested, and we would rather measure it than assume it.
Because a faultless film with a weak closure still leaks, and the zipper is where these bags usually fail. We fit a heavy-duty profile that closes harder than a standard press-to-close strip, or a certified child-resistant assembly where the category requires it.
Film gauge runs 0.12 to 0.20 mm, heavier than a standard pouch, so the bag stays rigid enough for the zipper to seat properly. A tamper-evident heat seal above the track gives a true seal until first opening.
The CR zipper assembly is tested to 16 CFR 1700.20 and we supply the test documentation with the order. Certification applies to the closure, so film and zipper are specified together and cannot be swapped after the fact.
The closure needs two coordinated actions to open. That is the regulated component in most cannabis programmes, and it is the thing an inspector asks for. We keep the paperwork on file for reorders so it does not have to be re-issued each time.
Matte lamination, to the point that nearly every premium brand uses it, with soft-touch as the current premium signal. Spot gloss over matte gives logo contrast without added colour. Holographic film is popular on limited drops.
A metallic reveal leaves areas unprinted so the foil shows as mirror silver. Gloss is the value tier and less common at the premium end. There is no clear window on this product, since the foil barrier that stops odour also stops light and a window would break both.
Common fills are 1, 3.5, 7, 14 and 28 g, and the bags run 3 x 4.5, 4 x 6 and 5 x 8 inches to cover them. Sizing follows the volume of the fill rather than the weight, and dense and fluffy products at the same gram figure can need different bags.
We leave room on the back panel for the compliance marks your state requires, and the bag has to be sized so that panel is flat and readable. Send us the fill and the panel copy and we'll size around both.
Foil odour-barrier bags run from 500 pieces per size and artwork. The foil laminate and CR closure make them dearer per unit than a standard pouch, and the price tiers down above 1,000. Test documentation is included at any quantity.
Orders scale to 100,000 pieces. Brands with several strains usually run the shared elements on one master design and change only the variable panel, which keeps each SKU at the minimum without a fresh setup.
Standard production takes 7 to 10 business days and a rush takes 5 to 7 business days. Samples ship in 5 to 7 business days and the sample charge is credited against the bulk order.
Fill the sample, close the zipper and seal it in a jar for a day, then open the jar. If you can smell anything, the closure or the film is wrong and we adjust before the run. That is a crude test, and it catches most problems.
No, and we would rather say so than pretend otherwise. The aluminium foil layer that delivers the odour barrier is also what stops the laminate going through a kerbside stream. A mono-material film would be recyclable, and it would not hold odour.
Where the compliance rules allow it, the honest route is to keep the pack small, print the disposal instruction plainly and put the effort into a bag that does its job for the full time it is on the shelf.
