概况(OVERVIEW)
中封四边封设备适用于食品茶叶等轻型包装，可生产中封袋和四边封袋。中封袋袋体两侧没有封边，保证了包装正面的图案完整，比较美观。由于封口在背面,袋体两侧可承受更大的压力，包装不易破损。四边封袋在内容物充足的情况下底部可放平使之呈站立状态，节约摆放空间且能更直观地将产品展示给消费者。
Center seal,four side seal equipment is suitable for light packaging such as food and tea, which can produce center seal bags and four-side sealing bags. There is no edge on both sides of the bag body, which ensures the complete pattern on the front of the package and is more beautiful. Since the seal is on the back, both sides of the bag body can withstand greater pressure, and the package is not easy to break. In the case of sufficient contents, the bottom of the four-sided sealing bag can be placed flat to make it stand, saving space and displaying products to consumers more intuitively.
