The Product

Custom-printed, smell-proof

One ounce mylar bags for dispensary buyers and serious consumers. The 1 oz format is the largest retail size. Your bag needs to hold 28 grams without blowing out and still look good on the shelf.

Built for cannabis. Made factory-direct.

The Ounce Bag Is Heavy Duty

Twenty-eight grams is the most flower you'll put in a single retail bag. That's real weight. Most ounce bags on the market are underbuilt because brands don't want to spend on thicker film. Then the bag fails, the product spills, and the customer is gone.

We build ounce bags at 5 mil minimum, often 6 mil for dense indica strains. The bottom gusset is double-sealed. The side seams are reinforced. When you pick up our ounce bag, you can feel the difference. It's rigid, not floppy. It holds its shape on the shelf.

The Ounce Customer

The ounce buyer is your best customer. They spend the most, they come back the most, and they tell their friends. They also know packaging. They've had bad bags that dried out their flower. They've had zippers that broke after a week. When you give them an ounce bag that actually works, they notice.

At 28 grams, your customer is storing this bag for a month or more. The barrier has to hold. Our metalized film keeps oxygen and moisture out for the long haul. Add a size 8 Boveda pack and your flower stays at 62% humidity for the entire time.

Print at this size gives you a billboard. You can do full brand artwork on the front, compliance data on the back, and strain storytelling on the sides. We do rotogravure printing for high-volume ounce bag runs because the color consistency is better and the per-unit cost drops fast above 10,000 units.

What we make

  • 5-6 mil thickness rated for 28g flower weight
  • Double-sealed bottom gusset for shelf-standing display
  • Rotogravure printing for runs above 10,000 units
  • Expandable bottom for upright shelf presentation

One honest, all-in price.

We work directly with a bench of factories - not as a broker. So we match you to the right one and bring back the best all-in price: packaging, printing, shipping, and any duties or tax - in one number with no middleman and no surprises.

Compliance standards we build to

Every product we make meets or exceeds the relevant regulatory standards. We provide the actual test certificates with every order, not just a claim on a website.

Product Knowledge

Is This the Right Packaging for Your Product?

28g (one-ounce) Mylar bags serve larger retail and value formats. Using PET/VMPET/PE or PET/AL/LLDPE construction, these bags require 5.0 mil or greater thickness to handle the substantial payload weight and volume. At one ounce, the bag must resist puncture from a significant quantity of dried flower material while maintaining barrier integrity across a large surface area. The large headspace volume at this size makes the quality of the aluminum foil layer the single most important factor in shelf life. A true AL foil structure achieves near-zero OTR and MVTR, protecting the product for 12-18 months under proper storage. VMPET-only structures at this size will allow measurable degradation over time. The ounce format is primarily used for value-oriented retail and bulk-to-retail transitions, where cost-per-gram is the primary consumer consideration.

Ideal For

  • ✓ 28g / one ounce of dried cannabis flower
  • ✓ Value-oriented retail formats
  • ✓ Bulk-to-retail transitions

Not Ideal For

  • ✕ Individual serving packaging
  • ✕ Liquid extracts
  • ✕ Products requiring rigid crush protection

Material Specifications

ConstructionPET/VMPET/PE for budget options; PET/AL/LLDPE for premium preservation (AL foil strongly recommended at this size)
Thickness5.0 mil minimum (substantial payload requires thicker walls for puncture resistance and barrier integrity)
Oxygen Barrier (OTR)OTR <= 0.01 to 0.5 cc/m2/day with AL foil; 0.5 to 1600+ with VMPET only
Moisture Barrier (MVTR)MVTR <= 0.01 to 1.0 g/m2/day with AL foil; 1.0 to 6.0 with VMPET only
Light Protection100% opaque with aluminum foil layer
Odor BarrierComplete with AL foil construction; reduced with VMPET-only budget options

At 28g, the large headspace volume contains significant oxygen that will degrade THC to CBN without a premium AL foil barrier. The payload weight also requires 5.0+ mil thickness to prevent puncture from dried flower material. Proper barrier maintains 58-62% RH for 12-18 month shelf life.

Questions

Everything you need to know.

What's the difference between 5 mil and 6 mil for ounce bags?
For fluffy sativa strains, 5 mil is fine. For dense indica that packs tight, go 6 mil. The extra mil prevents puncture when the bag is under pressure in shipping or on the shelf.
How many units before rotogravure makes sense?
Around 10,000 units. Below that, digital or flexo is more cost-effective. Above 10,000, rotogravure plate costs spread out and the per-unit print cost drops significantly. The color also stays perfectly consistent across the whole run.
Can ounce bags stand up on a shelf?
With a bottom gusset, yes. We design our ounce bags with an expandable bottom so they stand upright on dispensary shelves. This requires the right gusset depth and bag dimensions. We'll spec it for you.
What humidity pack size works with an ounce?
Size 8 Boveda for 28 grams. It's designed for that volume. A size 4 is too small and won't maintain humidity across the full bag. The pack should sit in the middle of the flower, not crammed at the bottom.
What materials are 28g ounce mylar bags made from?
PET/VMPET/PE for budget options; PET/AL/LLDPE for premium preservation (AL foil strongly recommended at this size). At 28g, the large headspace volume contains significant oxygen that will degrade THC to CBN without a premium AL foil barrier. The payload weight also requires 5.0+ mil thickness to prevent puncture from dried flower material. Proper barrier maintains 58-62% RH for 12-18 month shelf life.
What products are 28g ounce mylar bags best for?
28g / one ounce of dried cannabis flower, Value-oriented retail formats, Bulk-to-retail transitions.
What is the minimum order for 28g ounce mylar bags?
MOQ: 1,000 units for digital prints; 10,000+ for bulk runs. Production takes 10 to 15 business days.
Is 28g ounce mylar bags child-resistant certified?
Available with CR zipper or heat-seal with tear notch
Are 28g ounce mylar bags FDA compliant?
Food-grade materials (FDA 21 CFR 177.1520 compliant)
