Vacuum packaging machine

The vacuum packaging machine consists of a vacuum system, an air extraction and inflation sealing system, a heat-sealing system, and an electrical control system. The external suction vacuum packaging machine evacuates the air inside the packaging bag to a low vacuum level and then automatically seals it immediately. For certain soft foods, packaging with a fully automatic vacuum packaging machine can reduce the packaging volume, making transportation and storage more convenient. The principle of the desktop vacuum packaging machine involves using plastic composite films or plastic-aluminum foil composite films as packaging materials to perform vacuum packaging or vacuum air extraction packaging for solids, liquids, powders, pastes, such as food, chemical products, electronic components, precision instruments, and rare metals.
