This equipment adopts constant temperature heating technology and pneumatic driving system to realize accurate packaging. Its complete working process is smooth and efficient. Firstly, workers wrap products with shrink films such as POF, PVC and PE, then place goods evenly on the conveyor platform. After starting the machine, the L-shaped heating knife automatically falls down. Within one second, it finishes edge sealing and redundant film cutting simultaneously. After short cooling, the cutter lifts up automatically, and semi-finished products are sent into the heat shrink tunnel. With hot air circulation inside the tunnel, the packaging film shrinks closely and fits the product surface perfectly, achieving dust-proof, moisture-proof and anti-collision packaging effects.

　　There are two mainstream types for different production capacity demands: semi-automatic and fully automatic sealing cutting machines. Semi-automatic models require manual feeding and start control, featuring low price, small floor space and low maintenance cost. They are suitable for small factories and small-batch packaging orders. Fully automatic machines realize unmanned continuous feeding, film wrapping, sealing and cutting, greatly improving packaging speed. They can work cooperatively with assembly lines to meet large-volume and high-speed production needs. Besides, side-sealing sealing cutters are specially designed for ultra-long products with no limit on packaging length.

 
　　Compared with manual packaging and old packaging machines, modern sealing and cutting machines have outstanding advantages. Firstly, high efficiency. The automatic model can finish 20 to 30 packages per minute, greatly saving labor cost. Secondly, uniform packaging effect. Constant temperature control avoids scorched edges, broken seals and uneven cuts, making all package appearances consistent. Thirdly, strong flexibility. Operators can simply adjust heating temperature, conveying speed and sealing time via touch screens to adapt to products of different sizes and various shrink films.

　　In addition, the machine is equipped with complete safety protection devices, including emergency stop buttons, anti-pinch sensors and high-temperature protective covers, which effectively prevent scalding and clamping accidents during operation. Regular daily cleaning and routine maintenance can effectively reduce machine failures and extend service life. As automated packaging upgrading accelerates globally, high-efficiency, energy-saving and intelligent sealing and cutting machines have become the preferred packaging equipment for most manufacturing enterprises.
