packaging industry and just recently we discovered how novel they would be if they were used as coffee valve bags versus the traditional fold over type of approach. The traditional coffee bag is great when it is full of coffee or coffee beans but as the picture on the left shows, the bottom is an issue. This bottom is known as a quad seal and as the coffee is taken out of the pouch it comes more and more into play. Even further, the fact that the material used for coffee pouches is traditionally thicker film and/or foil because coffee requires very strong barrier protection the quad seal at the bottom can make a coffee bag unstable on a store shelf.
As we all know, first impressions are critical to a consumer and regardless of how incredible the coffee is, if the coffee valve bag is leaning, seems unstable or has even fallen over, human nature tells us a shopper's eyes will be drawn to what they can see, what looks nice, stable, etc. So, with that in mind, when the flat bottom stand up pouch was introduced, the coffee and tea market was one of the first places that stood up and took notice.
Flat bottom coffee valve bags stand up, well, flat. By design the side gussets and the bottom gusset are the same which creates a more "box like" design which then has another distinct advantage in that they hold more. Again, flat bottom coffee valve bags will hold more than other types of packaging, a box, a jar, and of course a traditional quad seal coffee bag.
Flat bottom coffee bags are made with the same heavy duty barrier films laminated together to create properties that protect the contents from moisture, vapor, odor, or any other negative element. They are available with and without gas release valves too. Even further, because each of layers including the printing serve a distinct purpose in the overall construction, the printed layer is trapped between other films so it cannot be scratched or marred in any way. So, the printing on flat bottom coffee valve bags is every bit as bold, dynamic, and photographic as traditional coffee bags, or any other type of retail packaging for that matter.
To be clear, flat bottom coffee valve bags use 12% less film yet hold more than traditional coffee bags, so it is a good idea to get samples and fill with your product to be sure what size works best for your particular application. Flat bottom coffee valve bags can have a ziplock too instead of a tin tie although tin ties are still available.
In a world of copy-cats, consider a flat bottom coffee valve bag so your product stands up and stands out and flies off of the store shelves!
