Commonly used classification methods can be divided into main packaging machinery and auxiliary packaging machinery according to packaging technology. The packaging machinery that completes the packaging process such as packaging, filling and filling is called packaging host, or packaging host; The packaging machinery that completes washing, drying, testing, stamping, measuring, conveying and palletizing is called auxiliary packaging machinery.

(1) packaging machinery

Package packaging machinery is used to package bulk products, which can be divided into kink packaging machine, end folding packaging machine, pillow packaging machine, envelope packaging machine and stretch packaging machine according to different package technologies.

(2) Filling and packaging machinery

Filling and packaging machinery is used to package powdery and granular solid articles. Filling and packaging machinery includes direct filling and packaging machine and bag-making and packaging machine. The direct filling and packaging machine adopts prefabricated paper bags or plastic bags for filling, and can also be directly filled into other containers. Bag-making and filling packaging machine is a kind of packaging machine that not only completes the forming of belt-shaped containers, but also completes the two processes of loading products into containers.

(3) Filling and packaging machinery

Filling and packaging machinery is used to package fluid and semi-fluid articles. According to the process of filling products, it can be divided into atmospheric filling machine, vacuum filling machine and pressurized filling machine. Filling and packaging machinery is usually connected with sealing machine and labeling machine to form a mechanized filling assembly line.

(4) sealing machinery

Sealing machine is suitable for sealing all kinds of packaging containers. According to the different sealing technology, it can be divided into glass jar sealing machinery (gland, gland, etc. ), bag mouth sewing machine, box sealing machine, plastic bag and paper bag sealing machine.

(5) Labeling machinery

Labeling machine is used to stick trademark paper or labels on packages.

(6) Binding machinery

Binding machines include binding machines, binding machines using strapping material with thread or rope, etc.

(7) Cooked packaging machinery

Cooked packaging machinery is divided into blister packaging machine and body-fitted packaging machine according to different processing technologies.

(8) Vacuum packaging machinery

Vacuum packaging machinery can be divided into vacuum packaging machine and inflatable packaging machine according to whether inert gas can be filled after vacuum pumping.

(9) shrink packaging machinery

Shrink packaging machinery includes not only small shrink packaging machines that can be used for sales packaging of single products or multiple products, but also large shrink packaging machines that can be used for transportation packaging including pallet packaging.

(10) Other packaging machinery

In addition to the above-mentioned types of packaging machinery, there are bottle washing dryers, packaging materials and specifications testing machines, punching machines, metering machines and so on. These independent machines are usually combined with other packaging machines to form a packaging unit.

General packaging machinery:

(1) bag-making, filling and sealing packaging machine

The main processes of bag making, filling and sealing packaging machine are packaging bag forming, filling, sealing and cutting. The packaging materials used are mainly film products, such as plastic film, paper, lead foil, composite film and so on.

(2) thermoforming packaging machinery

Thermoforming packaging machinery is divided into blister packaging machine and body-fitted packaging machine according to the different packaging container forming processes. Blister packaging is currently the most widely used packaging. This is a packaging method that seals the product between the preformed blister and the bottom plate. Body-fitted packaging is similar to blister packaging, and the difference between them is that body-fitted packaging products are used as molding dies, while blister packaging is molded by special dies. Close-fitting packaging can fix the product, so that the quality of the product will not be damaged by collision during circulation.

Shrink packaging machinery is a packaging machinery that wraps articles (or inner packaging) with stretch-oriented heat-shrinkable film, and then appropriately heats the film to shrink, so as to tightly wrap articles (or inner packaging). The shrink film is tensioned by the upper and lower reels, and the product is pushed to the film by the machine parts. After the film wraps the product, the sealing part seals the film on three sides, and then transports it by conveyor belt. It is forbidden to wrap the product by heating device and cool it to form shrink packaging.
