The difference between stretch film vacuum packing machine and ordinary vacuum packing machine

Stretch film vacuum packing machine is a vacuum packing machine, but it is not the same as the ordinary two-chamber vacuum packing machine. There is a fundamental difference in structure between the two types of equipment. Many customers do not know the difference between the two at the time of purchase. The following is a brief description of the difference between stretch film vacuum packaging machine and other food vacuum packaging machine.

1. Different packaging materials: like double-chamber vacuum packing machine or extraction-type vacuum packing machine, the packaging material is vacuum bag, while the packing material of stretch film vacuum packing machine is PE film and roll film material. This is an easy point to distinguish after packaging.

2. Different working principles: ordinary vacuum packing machine is bonded together by sealing, while stretch film vacuum packing machine is ironed off by heating wire. The two-chamber vacuum packing machine has only one studio, and the stretch film vacuum packing machine is divided into two vacuum chambers through the body film. The membrane is fitted through the pressure difference between the two vacuum chambers.

3, vacuum packaging machine price is different: because of the stretch film vacuum packaging machine production process is more complex, the production cost is higher, so the stretch film vacuum packaging price is slightly higher than the ordinary vacuum packaging machine price.
