Smell-proof ziplock bags are aluminium-lined storage pouches that lock in odour, block UV light, and keep your herb fresh between sessions. These G-Rollz smell-proof ziplock bags come eight to a pack at 105 × 80mm — the right size for a few grams of flower, a pre-rolled stash, or edibles you'd rather not have broadcasting their presence from inside your bag.
Why bother with proper stash bags
Regular sandwich bags do nothing to contain terpenes. Polyethylene is porous to these aromatic compounds — the molecules that give each strain its character slip straight through cheap plastic within 4-6 hours. That's why your jacket pocket smells like a Dutch coffeeshop two days after you last opened the bag.
These G-Rollz smell-proof ziplock bags use an aluminium inner layer, which is what actually stops odour molecules escaping and keeps UV light from degrading cannabinoids. Studies suggest up to 16% cannabinoid loss per month occurs in transparent containers exposed to daylight. Eight bags per pack means you can split strains without cross-contaminating flavours, or keep a few in rotation for travel, storage, and sharing.
G-Rollz Banksy 'Mona Launcher' design
G-Rollz is a Swiss accessory brand founded in 2017 that licenses Banksy artwork across their rolling papers, trays, and storage. This pack features the 'Mona Launcher' print — Mona Lisa holding a rocket launcher, which is the kind of thing that either makes you smile or it doesn't. The artwork is printed on the outside; the inside is plain aluminium doing the actual work.

What fits in 105 × 80mm
These bags hold approximately 3-7 grams of dried flower depending on density, or roughly ten pre-rolls laid flat. They're not a jar-replacement for long-term home storage — for that you want glass. These are for portability, separating strains, and short-to-medium term freshness. If you want to buy something for stashing quarter-ounces or more, look at the larger size variants G-Rollz produces.
How G-Rollz compares to other stash bags
Compared with budget mylar pouches, G-Rollz uses a thicker aluminium layer (roughly 60 microns versus 30-40 on generic options) and a more robust ziplock track. Smell Proof Inc. pouches, sold around €12 for a pack of 5, perform similarly on odour but lack the water-proof rating. Stashlogix canvas cases offer lock-and-key security but cost 5-10× more. For everyday discretion at the cheapest per-bag rate, G-Rollz sits in a comfortable middle ground.
Pair these with a proper glass stash jar for long-term home storage, and order a G-Rollz rolling tray if you're building out the kit. The jar handles your main stash; the bags handle everything that leaves the house.

| Expected seal cycles | 15-20 before loosening |
| Freshness window | 3-6 weeks with air pressed out |
How to use
- Break down your herb before sealing — whole buds take up more space and trap air pockets.
- Press the air out as you close the ziplock. Less oxygen means slower cannabinoid degradation.
- Run your fingers firmly along the seal to confirm it's fully closed. A half-sealed bag defeats the point.
- Store at room temperature (15-21°C), away from direct heat. The aluminium handles UV, but heat still dries out trichomes.
- Rinse with warm water and let dry fully for 24 hours before reusing with a different strain.
From Our Counter
Our Amsterdam shop staff have been using these behind the counter for splitting sample strains since 2022. The honest report: bags 1-5 of a pack get heavy rotation and still seal well after three months of daily handling. Bags 6-8 usually stay pristine as spares. Customers who buy them for travel consistently come back for more — which is the simplest test a product can pass.
The honest limitation
The ziplock is the weak point on any reusable pouch — after 15-20 open/close cycles the seal can loosen by roughly 20-30%. You'll still get good smell containment, but don't expect the 50th use to perform like the first. At eight bags for the price of a coffee, that's a fair trade. If you want a permanent solution, get a glass jar with a silicone gasket and use these for transport only.
Frequently Asked Questions
Are these actually smell-proof or just smell-reducing?
The aluminium lining blocks odour effectively when the ziplock is sealed properly. If you can smell anything through a fresh bag, the seal isn't fully closed — run your fingers along it again.
Can I reuse them with different strains?
Yes. Rinse with warm water, let them air-dry completely for 24 hours, and they're ready for the next strain. Residual terpenes can linger on the inner surface, so a rinse between strong strains is worth the extra minute.
Will they work for edibles or concentrates?
For edibles, yes — they're water-proof and odour-proof, so gummies or chocolate travel fine. For sticky concentrates, use parchment or silicone first, then the pouch. Raw concentrate will bond to aluminium and ruin the bag.
How long does herb stay fresh inside?
Roughly 3-6 weeks if you squeeze the air out before sealing. For months-long storage, glass jars with 62% humidity packs still win. These bags are best for portability and shorter-term freshness.
Can airport or train sniffer dogs detect through these bags?
No pouch on the market is guaranteed to defeat a trained detection dog — we won't tell you otherwise. For everyday discretion in a bag or pocket, the aluminium lining does its job well.
Does the 105 × 80mm size fit in a pocket?
Yes, comfortably. The bags are flexible and flat when not fully packed, so they slide into jacket and trouser pockets without bulking out. About the size of a folded banknote.
Where can I buy replacement packs?
G-Rollz produces this design in continuous runs, so order another 8-pack when you're down to your last bag. The Banksy series rotates designs occasionally, so if you like a specific print, get a spare pack while it's in stock.
