100 Pack Matte Black Mylar Stand Up Bags - 5.5x7.8 Inches Smell Proof Resealable Pouch Bag, Sealable Foil Packaging Zipper Pouches for Food Storage

I used these Chamigon matte black Mylar bags for birthday party favors, and they turned out great. The color is a deep, even black with a nice matte finish that looks clean and professional. I used a UV laser to mark an image on each bag, and the material took the engraving perfectly—crisp lines and no melting or warping. The bags were easy to fill and seal, and the thickness feels just right—sturdy enough to hold small treats without tearing, but still easy to open without scissors. The seal closes tightly and gives that satisfying press you want to know everything’s secure. Overall, these bags are excellent value for the money. Great look, durable build, and easy to work with—perfect for custom projects or event use. I’ll definitely be ordering more for future events.

Great quality

I freeze dry a lot of items, and these are by far the best bag for long term storage. They seal very nicely and the product stays crispy on the inside- no outside humidity allowed in. I highly recommend these.

I've been using these bags for a couple of years now to bag homemade jerky in snack portions. Zero complaints. They are sturdy and my wife seals them with the heat from a vacuum sealer. We've been pretty rough on these bags, taking them on long hikes and even keeping them in our ski backpacks, which get compressed against the back of chair lifts. Not a single tear ever.

Perfect for storing things that you want to protect the flavor of, like loose tea... I also like to store my medications and supplements in these when I travel, to keep them fresh as possible.

We dehydrate food for camping and this is a perfect size for a 2 person meal. Stays warm for hours and the ziplock part is very sturdy. Stands up well.

I didn’t choose the right size, but the bags were good.

Came as expected
