How packing machine works?

Although the working principles of different types of packaging equipment systems and different packaged products will vary, in general, the typical packaging machine works as follows:

Product feeding:

The packer receives products in various forms, such as solid items, liquids, powders, or granules, through a hoist, hopper, or other feeding system.

Container Preparation:

The packer prepares the container in which the product will be packaged. This may involve automatic bag making, clamping open pre-made bags, erecting cartons or boxes, and various other packaging situations.


The product is filled into the container by means of a filling system. Depending on the type of product and packaging requirements, this can be done using volumetric fillers, piston fillers, liquid pumps or other appropriate methods.


After filling the packaging machine seals it. This is typically done by heat sealing, glue sealing, zipper sealing, cap application, or other sealing methods specific to the package type.

Labeling and coding:

Some packer machines may come with an integrative labeling or coding system, if needed, to facilitate labeling, barcoding, or dating of containers.

Inspection and quality control:

Packaging machines may include inspection systems to check the quality of the package, such as to ensure proper sealing, correct fill levels, or the absence of contaminants. Any defective packages may be automatically rejected or flagged for manual inspection.

Conveying and Output:

Packed finished products are conveyed out of the packer for subsequent packing, boxing, processing operations, etc.

The basic functions of the package solutions include:

  1. Packaging material supply:

    Containers such as plastic roll film, pre-made bags, glass bottles, box cartons etc. are guided to the working area of the automatic packing machine by means of appropriate devices.

  2. Product feeding:

    The product to be packed is conveyed to the corresponding position of the automated packaging equipment for packing by means of a conveyor belt, conveying system or other device.

  3. Packaging process:

    The packing sealing machine performs a series of operations such as automatic filling, sealing, labelling, strapping and wrapping according to pre-set parameters and programs to ensure that the product is placed safely in the container.

  4. Control system:

    The pack machine is equipped with a control system, usually a PLC (Programmable Logic Controller), to monitor and control the packaging process. It allows the speed, positioning, timing and other parameters of the packaging machine to be adjusted to suit different products and packaging requirements.
