The specific working principle of compression packaging machine

Mechanical compression principle: usually relying on mechanical structures composed of mechanical screws, motors, etc., or using the strong pressure generated by hydraulic pressure and air pressure to squeeze out most of the air in the packaged product, so that the product is compressed into a certain thickness or shape, and then packaged with packaging materials.

Vacuum compression principle: first extract the air in the packaging cavity to form a vacuum environment, and then compress the product under the action of external atmospheric pressure and complete the packaging. This method can more thoroughly exhaust the air and achieve better compression effect and preservation performance.
