There are many methods for packaging machine classification, each of which has its own characteristics and application range, but all have its limitations. From the general situation of packaging machinery in the world, the more scientific classification method is classified according to its main function, which can grasp the essence of things. The basic category is as follows:

(1) filling machine

(3) wrapping machine

The wrapping machine is a flexible packaging machine that wraps all or part of the packaging.

(4) multi-function packaging machine

This type of packaging machine has two or more functions. The main types are:

1.Seal filling machine. It has two functions of filling and sealing.
Mold filling and sealing machine. It has molded, filling, sealing three functions. The types of molding are bag molding, bottle molding, box molding, bubble molding, melting molding and so on.

When the packaging material of the reel passes through the outer wall of the material channel, it is wound into a barrel by the former. The transverse seal completes the top seal of the packing bag and the bottom seal of the next bag, becoming two welds. As the feeding channel is wrapped by the packaging bag, the bottom sealing can be directly fed into the bag after welding, and then move a station to complete the top sealing and cutting with the cutting knife to complete the packaging process.
