Back Seal Bags – Centre Seal Pouches That Put Your Brand Front and Center
The seal is on the back. The front is all yours. No seals, no creases, no interruptions – just a clean, uninterrupted canvas from edge to edge. Back seal bags (also called centre seal pouches or pillow pouches) give your brand the full front panel to work with, while the pillow shape adds shelf presence that flat pouches simply can’t match. At Wanhao, we make them in any size, any material, any finish – with the same quality standard we bring to every pouch we ship.
What Is a Back Seal Bag?
A back seal bag – also called a centre seal pouch or pillow pouch – has a single seal running down the middle of the back panel. The front and sides are completely seal-free. Fill it, seal the top, and the bag takes on a soft, rounded pillow shape. No side seals, no bottom gussets, no visual clutter. Just your design, front and center.
