What is a Back Seal Bag?
A back seal bag is a type of packaging bag that is sealed along the back side of the bag body, leaving no seals on the sides. This allows the sides of the bag to withstand greater pressure, reducing the likelihood of packaging breakage. In terms of design, it also ensures that the pattern on the front of the package is complete. The application range of back seal bags is very broad; they are lightweight and not easily damaged.
In the competitive world of flexible packaging, precision is key. Whether you need a specific pouch custom fit for coffee, snacks, or liquids, understanding volume is just the first step.

Back seal bags are also known as pillow-shaped bags. These bags have rear, top, and bottom seams, giving them a pillow-like shape. Many small food packages often use pillow-shaped bags. The rear seam of a pillow-shaped bag forms a fin-like seal, in which the inner layers of the film are sealed together, and the seam protrudes from the back of the sealed bag. Another type of sealing is the overlap seal, where the inner layer of one side is bonded to the outer layer of the other side, forming a flat seal. Since the "fin" type seal is relatively strong and requires only the inner layer of the packaging material to be heat-sealable, it is widely used. In contrast, the "overlap" type seal is relatively less strong and requires both the inner and outer layers of the bag to be heat-sealable materials, so it is not used as much. The top and bottom seals are formed by bonding the inner layers of the packaging bag.
Advantages of the back seal bag Structure: Continuous patterns, high pressure resistance, less prone to damage, lightweight.
Suitable Products for back seal bags: Instant noodles, dairy products, puffed food, candy, and snacks.
