Ordering the wrong mylar bag size is one of the most common — and most avoidable — mistakes in cannabis packaging. A bag that's too small won't seal properly. A bag that's too large has excess dead space that looks unprofessional and lets air pocket around the product. And discovering the problem after you've ordered 1,000 units is an expensive lesson.
This guide covers everything you need to match the right bag size to your product — and make the right finish, style, and quantity decisions while you're at it.
Mylar Bag Sizes for Cannabis Flower: The Quick Reference
| Bag Size | Cannabis Weight | Common Name | Notes |
|---|---|---|---|
| 1 Gram | 1g | Single gram | Entry price point; sample and gifting use cases |
| 1/8 Ounce | 3.5g | Eighth | The most common retail unit in cannabis — order the most of this |
| 1/4 Ounce | 7g | Quarter | Mid-tier value; popular with regular buyers |
| 1/2 Ounce | 14g | Half | Bulk buyer segment; higher margin per transaction |
| 1 Ounce | 28g | Zip / Ounce | Full ounce; gifting programs, bulk buyers |
Important caveat: Flower density varies significantly by strain and trim style. A dense, compact indica may pack tighter than a fluffy, airy sativa — meaning two different strains at the same gram weight may fill a bag differently. Test your specific product in the bag before ordering in volume. Order a 100-unit trial case, fill a sample, seal it, and evaluate the result.
Choosing a Finish: Matte, Gloss, Holographic, or Metallic?
Once you've got the size right, finish is the next decision — and it has real implications for brand presentation, label application, and shelf performance.
Matte Black — the premium standard in cannabis retail. Non-reflective, understated, and consistently associated with quality positioning. Matte surfaces are also the easiest to apply labels to — no glare, no bubbling. If you're not sure what finish to pick, start here.
Gloss Black — bolder and more attention-grabbing than matte. Reflects light, photographs well, and commands more shelf presence at a distance. The trade-off: labels can look slightly less crisp on a gloss surface, especially if applied by hand.
Gloss Silver / Gold — metallic finishes that stand out immediately in a display case. Excellent for top-shelf strains and limited-edition releases where you want the packaging to signal premium before the customer reads a word.
Holographic — the fastest-growing finish in cannabis packaging. The rainbow-shifting iridescent surface catches every light source in a dispensary and makes the bag nearly impossible to ignore. If you're targeting a younger, lifestyle-forward consumer, test a holographic case alongside your standard finish.
Kraft & Clear — the natural, artisan look. Popular with craft cultivators and brands positioning around organic or sustainable values. Takes printed labels cleanly and has a distinctive feel that standard black bags don't have.
Window vs. Fully Opaque: Which Do You Need?
Many states require that cannabis retail packaging be fully opaque — meaning the product inside cannot be seen from the exterior. Check your state's specific requirements before choosing a bag with a clear window.
If your state allows it (or if you're packaging for a market that doesn't restrict it), a clear window bag lets the flower be the visual — which can be a genuine sales tool for premium, visually distinctive product. A matte black back with a clear window is one of the most popular configurations in our catalog precisely because it balances premium branding with product visibility.
100-Unit Trial Cases vs. 1,000-Unit Wholesale Cases
We offer most mylar bags in both 100-unit trial cases and 1,000-unit wholesale cases. Here's how to think about which to order:
Order 100 units when: You're testing a new bag size or finish for the first time, launching a new strain with uncertain volume, building a sample kit of multiple formats, or starting a new operation and establishing your packaging baseline.
Order 1,000 units when: You've validated the format and know it works for your product, you're restocking a format you've used before, or you want to maximize your per-unit cost efficiency. At the 1,000-unit tier, prices drop to as low as $0.05/unit — a significant savings over the 100-unit price.
The math is simple: if you're going to use more than 200–300 bags of a format over the next few months, the 1,000-unit case almost always pencils out better even accounting for storage space.
Do You Need Child Resistant Bags?
Most regulated markets require CR packaging for cannabis retail. If you're using mylar bags as your primary consumer-facing packaging (not just as inner packaging inside a CR bag), make sure you're ordering from our Child Resistant CR Bags collection — not standard mylar bags, which aren't CR-certified.
If you're packaging product in standard mylar bags that then go into a CR exit bag at the dispensary counter, the standard bag is fine for the inner packaging role.
