Extending the sturdy structure and display advantages of the five panel bag, the large version increases size and load capacity to meet industries that require high-volume, high-strength packaging. Thomson is the only manufacturer in Taiwan capable of producing oversized five panel bags and has developed a patented vent-hole technology that solves degassing and storage issues, delivering a flagship solution that balances aesthetics, functionality, and production efficiency.

Main Structure and Sealing Method
    Like the standard five panel bag, the large version has front, back, two sides, and a bottom panel. The difference lies in reinforced design: thicker films, wider seals, and a K-shaped bottom ensure the bag stands firm even under heavy loads. Space is reserved for a vent module, allowing installation of Thomson's patented vent holes to balance sealing with gas release, especially useful for powders or gas-producing contents.
Features and Advantages
    Beyond the rigidity and printable surfaces of standard five panel bags, the large format achieves breakthroughs in load-bearing and ventilation. It offers a wide opening, heavy-load stability, and can be repeatedly moved or stacked. The patented vent design releases internal gases after sealing to prevent bulging and maintain product integrity, earning popularity with European and American clients for food processing and large retail markets.
Common Applications
    Ideal for products requiring large capacity and strong shelf presence, such as bulk coffee beans, large bags of pet food, dried goods, grains, tea, and nutritional powders. With its solid appearance and vent design, brands can ensure stable logistics while presenting a premium image in stores.

    Thomson is the industry's only provider of extra-large five panel bags and holds exclusive know-how for vent-hole applications and sealing. Besides custom sizing and reinforced seams, we offer zipper integration, handle processing, tear-resistant structures, and print registration services, ensuring each bag meets functional, visual, and production requirements for both export and domestic premium markets.
