Back seal packaging plastic bag

Compared to other packaging forms, the back sealed bag ensures a complete and aesthetically pleasing pattern on the front of the packaging due to the lack of edge sealing on both sides of the bag body. At the same time, in terms of layout design, the bag pattern can be designed as a whole to maintain image coherence. Due to the sealing on the back, both sides of the bag can withstand greater pressure, reducing the possibility of packaging damage. Moreover, packaging bags of the same size are sealed with a back seal, which minimizes the total length of the seal and reduces the probability of cracking.
