What is a Quad-Seal or Stabilo Bag Pouch? Here at K-Flex, we call this a True Side Gusset Pouch. It is a bag styled prominent for stand-up displays. This style of packaging has a wide face that is great for labels, graphics, and can have a center or off-center vertical graphic, working best for the front and backside of the packaging. This pouch is suitable for almost all industries but most common in the Coffee industry.

This pouch is differentiated from a Terminated Side Gusset Pouch by its open side gussets all the way to the top prior to sealing.

What packaging machine is best for your quad-seal or stabilo bag?


A stabilo bag has a flat bottom that allows the packaging to remain upright on its own, even when it is empty. It will not fall over even as the contents decrease with usage.


Due to the bags square bottom this packaging leaves no dead space when loaded with content. Shipping efficiency is also improved with the ability to make these bags shorter or narrower for the same content volume than a straitional standing bag. This trait also contributes to the cost reduction as they can be more efficiently displayed on the retailers’ shelves.


This packaging offers a variety of printable surfaces. With the packaging wide faces and flat bottom that can easily hold vertical or horizontal designs. This allows for all four sides and the bottom to hold an eye catching design to increase appeal to consumers.


Packaging has the ability to be manufactured for small (1kg or less) or large bags up to 10kg with a choice of closures.

This style pouch can be produced on our Vertical Form-Fill-Seal Equipment or ran as a Premade Pouch.
