Side-sealed bags are a common packaging form characterized by the sealing located along the edge of the bag, providing enhanced sealing and protection. This design reduces the risk of accidental leakage or damage from external factors, thus prolonging the lifespan of the items. Side-sealed bags find wide applications in food packaging, medical, cosmetics, mailing, and transportation industries. The dimensions, shapes, and sealing methods can be adjusted according to specific requirements to ensure optimal packaging effectiveness and convenience of use.
