The commonly used classification method is to classify according to the packaging process, which can be divided into main packaging machinery and auxiliary packaging machinery. The packaging machinery that completes wrapping, filling, filling and other packaging processes is called main packaging machinery, or packaging host; the packaging machinery that completes washing, drying, testing, stamping, measuring, conveying and stacking is called auxiliary Packaging machinery.

(1) Wrapping and packaging machinery

Wrapping and packaging machinery is used to package block products. According to different wrapping processes, it can be divided into twist-type packaging machines and end-fold packaging machines. machine, pillow packaging machine, envelope packaging machine, stretch packaging machine, etc.

(2) Filling and packaging machinery

Filling and packaging machinery is used to package powdery and granular solid items. Filling and packaging machinery includes direct filling and packaging machines and bag making, filling and packaging machines. Direct filling packaging machines use preformed paper bags or plastic bags for filling, and can also be filled directly into other containers. The bag making, filling and packaging machine is a packaging machine that not only completes the forming of the container, but also completes the two processes of filling the product into the container.

(3) Filling and packaging machinery

Filling and packaging machinery is used to package fluid and semi-fluid items. According to the process of filling products, it can be divided into normal pressure filling machines, vacuum filling machines, pressure filling machines, etc. Filling and packaging machinery is usually connected with sealing machines, labeling machines, etc. to form a mechanized filling line.

(4) Sealing Machinery

Sealing machinery is suitable for sealing various packaging containers. According to different sealing processes, it can be divided into glass jar capping machinery (gland capping, screw capping, etc.), cloth bag mouth sewing machinery, box sealing machinery, and various sealing machinery for plastic bags and paper bags.

(5) Labeling Machinery

Labeling machinery is a machine used to paste trademark paper or labels on packages.

(6) Bundling Machinery

Banding machinery includes belt strapping machines, tying machines for wire or rope strapping materials, etc.

(7) Cooked packaging machinery

Matured packaging machinery is divided into blister packaging machines and body packaging machines according to different processing techniques.

(8) Vacuum packaging machinery

Vacuum packaging machinery can be divided into two types: vacuum packaging machines and inflatable packaging machines according to whether they can be filled with inert gas after being evacuated.

(9) Shrink packaging machinery

In addition to small shrink packaging machines that can be used for sales packaging of single products or multiple products, there are also shrink packaging machines that can be used to package pallets. Large shrink packaging machine including transport packaging.

(10) Other packaging machinery

In addition to the above types of packaging machinery, there are also bottle washing and drying machines, packaging material and specification testing machines, stamping machines, and measuring machines. Machines, etc., these single machines are generally combined with other packaging machines to form a packaging unit.

Common packaging machinery:

(1) Bag making, filling and sealing packaging machine

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

(2) Thermoforming packaging machinery

Thermoforming packaging machinery is divided into blister packaging machines and body packaging machines according to the different packaging container forming processes. Blister packaging is currently the most widely used type of packaging. It is a packaging method that seals the product between a preformed blister and a base plate. Skin packaging is similar to blister packaging. The difference between the two is that the product of skin packaging is used as a molding mold, while the blister packaging is formed by a special mold. Skin packaging can immobilize products so that product quality is not damaged by collisions during circulation.

Shrink packaging machinery uses stretch-oriented heat shrinkable film to package items (or inner packages), and then performs appropriate heating treatment on the film to shrink the film and tightly wrap the items (or inner packages) ) packaging machinery, the shrink film is tensioned by two upper and lower rollers, and the product has machine parts to push the film. After the film wraps the product, the three sides of the film are sealed by the sealing component, and then transported by the conveyor belt. Through the heating device, the The product is wrapped and cooled to form a shrink-wrap package.
