Three-side sealed bags feature a core design of "three sealed sides and one open side," boasting stable sealing performance. They effectively block moisture, oxygen, and odors, providing reliable protection for contents. With a simple and lightweight structure, they are ideal for small-capacity packaging needs—easily accommodating snacks, condiments, tea, and small daily necessities. The open-side design ensures convenient access, and they can be customized with different thicknesses, transparency levels, and printed patterns, balancing practicality with brand display. A cost-effective choice for small to medium batch packaging.
Flexible packaging is made from materials such as plastic films, aluminum foil laminates, and paper composites that can be formed into pouches, bags, or roll films. Compared with rigid packaging, it offers lower transportation costs, excellent barrier protection, and greater design flexibility.
