100 Pieces 16 Ounce White Kraft Paper Coffee Bags, Stand Up Coffee Pouches with One Way Degassing Valve and Reusable Side Zipper (Pull Tab to Open) Flat Bottom - Stand Up Well (16oz, 1lb, 454gram)

So I keep reading through feedback on these items and was skeptical about buying them. I used a food processing sealer. Since these bags are much thicker than a regular bag. 3x thicker, I put it in the sealer, turn on, left the bag in the sealer, turned it on 3 more times, Then I moved the bag down a little on the sealer and repeated the process. Although maybe a few more minutes of my time, It worked like a charm and the bags are beautiful so I don't mind the extra few minutes. The seal worked and held great! Hope this helps others.

It was very nice of the vendor to state the necessity for heat sealing, but the zipper seal is non-functional due to both layers of the seal being bonded to one side.Bought these to package coffee favors for my son's wedding. Thanks for the extra stress.These are defective and I'm returning them.

Used this for my coffee roasting business, the bags have a very nice feel and a matte finish, would recommend to anyone

Both sides of the zipper are on the same side of the inner bag. The instructions on the web says to press the line marked zipper on the outside of the bag, but with both sides of the zipper on the same side of the inner bag, it doesn't seal the contents. Makes no sense at all and renders this product useless.

Beautiful bag, quality looks good. I do not like the valve, it’s not possible to smell any product aroma

Perfect for coffee samples!
