Back Seal Bags

Back seal bags (center-seam bags / pillow pouches) feature a single seal line running down the center of the back panel, leaving the entire front face seamless — providing a large, uninterrupted print area for maximum brand impact. Made from PE, OPP/PE, BOPP/CPP, PET/PE, and metallized laminates. Widely used for automated packaging of bread, pastries, candy, noodles, wet wipes, hygiene products, apparel, and textiles. The pillow-style construction is optimized for vertical form-fill-seal (VFFS) machines for high-speed filling and sealing.
