Stand up pouches are a flexible and creative packaging method for food and non-food products. You can use these versatile pouches in a variety of situations. However, not everything is allowed in the realm of creative food packaging.
Let’s use a little imagination to understand. Think of yourself in a situation where you deal in beef jerky and need a beef jerky bag with vacuum packaging. You come to us. We suggest you to think carefully about using zippers and bottom gussets with vacuum packaging.
Bottom gussets
There are three popular bottom gusset types. If you want to use vacuum, we will advise you to go ahead with solid gussets that are a part of the pouch. These gussets are not adders. They are a part of the overall structure of the pouch. This quality makes them sufficiently strong to carry vacuum packaged products, so we have devised this solution.
Zippers
Zippers are an entirely different story. They are added to pouches during the final part of the assembly. They are heat sealed to the pouches. Sealing makes them the weakest link in stand up packaging – pouches are more likely to leak around the zippers and zip tapes.
Keep these weak links in mind when you order your batch of flexible pouches.
