DON'T FORGET THE STRAIN LABELING!
This matte black/clear 28g mylar bag holds an ounce in a resealable, smell-proof barrier bag with a heavy-duty zipper and a tamper-evident heat-seal top. The clear back lets customers see what they're buying, while the front stays clean for your own label or custom sticker. It comes in packs of 16 to 1,000, with a single sample bag available.
+ Elevate Your Brand with Blank 28g Mylar Bags
A blank 28g bag is the fastest way to a clean, professional package. There's no artwork competing with your brand: add your strain label and a custom vinyl sticker with your logo, and it looks like your own packaging, with no plates, setup fees or print minimums.
These bags work for more than flower. Customers use them for gummies and other edibles, herbs, spices, loose-leaf tea and anything else that needs to stay fresh and out of sight. They're a big step up from a plain zip bag: the mylar keeps out light and air, and the zipper locks in odor.

+ What Fits in a 28g Bag?
This size is made for a full ounce of flower. It's also a popular bag for bulk gummies, edibles and larger herb packs. For a half ounce, use our 14g mylar bags; for a quarter pound, step up to our 112g mylar bags.
Not sure? Order the single sample bag first and fill it with your product before you commit to a bigger pack.
+ How to Fill and Seal
1. Fill. Weigh out your product and drop it in. Keep the zipper track clean, since crumbs in the track can stop it from closing fully.
2. Zip. Press the zipper closed from one end to the other.
3. Heat seal. Seal straight across the top, above the zipper and below the tear notch, with a hand-held mylar bag sealer. A flat iron works in a pinch.
4. Check it. Give the seal a light tug. A good seal is flat and even, with no gaps.
Your customer tears the top at the notch to open it. After that, the resealable zipper keeps it closed between uses.
+ Tamper-Evident, Not Child-Resistant
This bag is tamper-evident: once the heat seal at the top is torn, you can tell it's been opened. It has a standard resealable zipper, so it is not child-resistant. If your state requires child-resistant packaging, choose one of our bags with "Child Resistant" in the name, or place this bag inside a child-resistant container.
Rules for cannabis and hemp packaging differ from state to state. Because this bag has a clear side, it won't meet rules in states that require packaging you can't see through; for those, choose a solid black, white or kraft bag. Always check your state's current requirements before you go to market. Questions? Call or text Zack at 843-457-0226.
+ Complete the Setup
Label the matte black front and let the clear back show off the product. Most brands finish this bag with:
• Strain labels (hybrid, indica, sativa)
• 28 gram or 1 ounce weight labels
• Your state's warning labels
• Your own logo, printed on custom vinyl stickers sized for this bag
Order the bags and labels together and everything ships in one box.
+ Want It Printed Instead?
If you'd rather skip labeling, our 28g mylar bags come with original in-house designs, ready to fill. For bags with your own brand printed on them, see custom 28g mylar bags.
+ FAQ
Are 28g mylar bags the same as ounce bags?
Yes. 28g mylar bags hold an ounce (28 grams), so people also call them ounce bags, oz bags or zip bags. Compare every size on our blank mylar bags page.
Are these matte black/clear 28g mylar bags smell proof?
Yes, once the zipper is closed and the top is heat sealed. The multi-layer mylar blocks light, air and odor, so the product stays fresh and discreet in storage and shipping.
Are these bags child-resistant?
No. This bag is resealable and tamper-evident once heat sealed, but the zipper is not child-resistant. If your state requires child-resistant packaging, see the child-resistant styles on our blank flower packaging page.
Do I have to heat seal them?
The zipper closes on its own, but the heat seal is what makes the bag tamper-evident, and many states require tamper-evident packaging for retail cannabis and hemp products. A hand-held heat sealer does it in a few seconds per bag.
Can I put my logo on blank mylar bags?
Yes. The easiest way is a custom vinyl sticker sized for this bag, printed from your artwork. For larger runs, ask us about fully custom printed bags.
+ Why Choose Creative Labz?
Bags that hold up. Our blank bags use multi-layer barrier film and heavy-duty zippers, so they close cleanly, heat seal flat and keep blocking light, air and smell between uses.
Not marketplace knockoffs. The cheap mass-market bags you see online are known for zippers that split after a few uses, thin film that lets smell through and sizes that don't match the listing. Your packaging is the first thing a customer judges, so a bad bag makes a good product look cheap.
A real shop with real people. We're a packaging shop in Myrtle Beach, South Carolina, supplying brands across the country since 2019. Every order ships from our own shop, not an overseas warehouse.

Everything in one order. Bags, strain and warning labels, custom stickers and heat sealers all ship together, so you're not waiting on three suppliers. Browse more plain bags and containers on our blank flower packaging page.
