This matte black/clear 448g mylar bag holds a pound 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 10 to 100.
+ Elevate Your Brand with Blank 448g Mylar Bags
A blank 448g 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 bulk herbs, coffee, tea, gummies 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 448g Bag?
This size is made for a full pound of flower, the standard bag for bulk and wholesale transfers. It also works for bulk herbs, coffee, tea and other bulk products. For a quarter pound, use our 112g mylar bags.
+ 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. 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)
• 448 gram or 1 lb 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 448g mylar bags come with original in-house designs, ready to fill. More plain bags are on our blank flower packaging page.
+ FAQ
Are 448g mylar bags the same as pound bags?
Yes. 448g mylar bags hold a pound (448 grams), so people also call them pound bags or LB bags. Compare every size on our blank mylar bags page.
Are these matte black/clear 448g 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.
