Center Back-Seal vs. Quad-Seal

Choose a center-back seal if you want a plain front panel for your design. Or, upgrade to a Quad-Seal to push all the seams to the corners. This gives you four flat sides for custom printing and makes the bag stand up straighter.

Questions & Answers

Common Questions About Side Gusset Bags

Get the facts you need to choose the right packaging structure for your product line.

A side gusseted pouch uses the weight of your product to form its base. A flat bottom bag has a stiff, pre-made bottom. Side gusset bags ship flatter, helping you save money on bulk freight.
Normal zippers struggle to seal across thick side folds, leading to air leaks. For items like side gusset coffee bags, we add a Pocket Zipper on the front panel, or use Tin-Ties. This keeps the coffee fresh and makes it easy for customers to reclose.
Yes. We make foil side gusseted bags that block out moisture and oxygen. To prevent heavy products from bursting the seams during shipping, we reinforce the seals and use strong inner films. Your products stay safe and dry.
Yes. With our custom printing, you can cover the main bag in a soft matte finish, but leave a clear, glossy window on the side gusset. This lets customers see your product inside.
