50 Pack Coffee Bags with Aluminum Foil and Degassing Valve, Resealable High Barrier Storage Bags, Odor-Proof for Coffee Beans, Stand Up Coffee Pouch, Flat Bottom (Small-8OZ, White)

Use an Iron to seal and be sure to put a cloth on the sealing surface to protect the black coating. If you do not then the coating will be marred by the iron.

Perfect for 8.8oz or 250g of coffee. Could probably fit 10oz but 8.8 works great for me

These bags do the job, but the black finish comes off a little bit when using a continuous band bag sealing machine. This just makes them look less professional.

First and foremost, the bag provides a good airtight seal for storing your coffee beans.You do need a heat sealer to accomplish this, but there are many low priced heat sealers available here on Amazon that work very well.The bags are heavy duty and durable.The zip lock is a little awkwardly located to access the contents, which is just a minor annoyance.For me, the deal breaker is that the pull tab often breaks making it difficult to access the zip lock.I won’t buy this style again and I do not recommend it.

Great bags. Ordered a second batch recently.

These seales great and worked as promised.

got these bags to offer our customers to grind the coffee to whatever grind they want and then be able to reseal them. These bags don't work which is very sad, not the fault of the seller, however the product doesn't work. I have tried at least tried 20 of the 50 bags delivered, not a single one at which the resealable strip worked, stayed attached

Unsure why all of the bags are not sticking. We used a commercial grade sealer and it would not work. The sealer needs to source a better bag that seals. Sorry to write a bad review but it needs to be rectified before selling more.
