The FQL-450QF pneumatic L-type sealing and shrinking machine consists of two parts: the sealing and shrinking machine, but these two parts are separate. They can all be used independently. This machine requires manual feeding, and then automatically completes the sealing and cutting work through cylinder pressurization, and then automatically enters the shrinking machine to complete the shrinking packaging. At the same time, it can automatically transfer the sealed and shrunk products to the next process. The transmission speed and sealing time of the machine can be set by oneself. This machine is more suitable for sealing and cutting square box products. This set of equipment is particularly suitable for large-scale shrink packaging in industries such as software, printing, biscuits, pharmaceuticals, ceramics, beverages, and flooring
