Two-layer composite back-sealed bag (customized models, please contact customer service to place an order)

タイトルまたは説明

Compared with other packaging forms, the back sealing bag has no edge sealing on both sides of the bag, so it ensures the integrity of the design on the front of the package and is more beautiful. At the same time, in the layout design, the bag pattern can be designed as a whole to keep the picture consistent. Since the seal is on the back, the two sides of the bag can withstand greater pressure, reducing the possibility of package damage. In addition, the total length of the back sealing is the minimum for the same size packaging bags, which also reduces the probability of sealing cracking in a certain sense.
