Semi-auto Sleeve Wrapper

ST-6030 Semi-auto Sleeve Wrapper adopts top brand cylinder in order to work stably when it pushing and sealing. Special design of the sealing blade makes sealing line deep-set, and avoids the film sticking the cutter. The electric spare parts are all top brands in order to make the machine works stably and perform perfectly.
Semi-auto Sleeve Wrapper with covert cylinder which is enhanced the convenience for the operator, meanwhile, pressuring device ensures the product without dithering, even the light ones. Plastic Wrap Machine has the adjustable front feeding frame ensure packing different shape products perfectly.

About the Shrinking Packing Machine:

SM-6040S adopts double motors to blow the hot air reach every corner inside the tunnel to make sure the perfect performance of shrinking and solid steel roller with durable silicone pipe for chain conveying.
SM-6040SM is a thick shaft roller style, for packing small size product specially and the speed of the Conveyor is controlled by frequency inverter. At the same time, shorter length of the tunnel body can save the energy, meantime good performance.
ST-6030 + SM-6040S is a simple and economic model of the sleeve wrappers series. It uses PE film, easy to operate, just push a button by hand to make the sealing automatic. By the other way, they combine the sealer and tunnel together, saving the working room, suit for the limited area and on the two sides of the machine, there are safe covers, to protect operators.
