Back seal bag:Compared with other packaging forms, sealed bags have no edge sealing on both sides of the bag, thus ensuring that the pattern on the front of the package is complete and more beautiful. At the same time, in the typesetting design, the bag pattern can be designed as a whole to maintain the continuity of the picture. Since the seal is 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 adopt the form of back seal to minimize the total sealing length, which also reduces the probability of seal cracking to a certain extent.
