How the Shrink Packing Machine works


The introduction to the Shrink Film Wrapping Machine:

Shrink Film Wrapping machine (PE Film shrink wrapping machine) is a machine that wraps the product with a heat shrinkable film and then heats it to shrink the film and wrap the product. According to the machine type, it is divided into drying tunnel shrinking packing machine, oven shrinking packing machine, frame shrinking packing machine, gun shrinking packing machine and so on.

The Working Principle of the film wrapping machine

Fully automatic shrink packing machine is a combination of pneumatic components and mechanical devices, automatic packaging equipment controlled by PLC and other peripheral circuits. The actuator of the device is a cylinder, and its forward and backward movements are controlled by a two-position five-way solenoid valve. The working position of the cylinder is detected by a magnetic switch and a proximity switch and fed back to the PLC. The PLC sends a control command to the solenoid valve of the corresponding cylinder through the program To control the movement of the cylinder. After packaging, the product can be sealed, moisture-proof, and impact-proof, suitable for multi-item wrapping and pallet packaging; digital display computer can control temperature automatically, the temperature difference is small; stable and reliable, low noise, long life;

Also the Automatic Shrink Sleeve Label Machine shares the same principle of the film wrapping machine


The advantages of the Reliable Film Wrapping Machine


During the shrinking process, it does not affect the quality of the packaging, but it can shrink quickly. The packaged product can be sealed, moisture-proof, and impact-proof. It is suitable for multi-item tight packaging and pallet packaging.

① Direct infrared heating is used;

② The equipment is small and compact, with short warm-up time and power saving;

③ Electronic stepless speed regulation;

④ Shrinkage does not affect the quality of the packaged items and can be packed well;

⑤ Applicable to the packaging of regular or irregular articles



The configuration of the shrink packaging machine mainly lies in the heat pipe and the heat insulation effect of the whole machine. These are the key factors that directly affect the shrink effect and the service life of the whole machine. Its heating tube is mainly divided into:

1. Quartz tube: It is directly heated by far infrared radiation, electronic stepless speed change, solid-state voltage regulator temperature control, stable and reliable. The quartz tube was adopted at the time of the initial development of the shrinking machine, mainly based on stainless steel heating. After the use of the majority of customers, the stainless steel heating tube is 8-10 times the life of the quartz tube.

2. Stainless steel heating tube: high-quality stainless steel heating tube, internal bidirectional heat circulation air, heat is uniform and constant. Using electronic governor to adjust the speed, the conveying speed can be adjusted arbitrarily to ensure the stability of the conveying and good shrinkage effect;


Scope of application

Packaging for glass bottles, styrofoam, cartons, toys, electronics, appliances, stationery, books, records, hardware tools, daily necessities, medicines, cosmetics, beverages, fruits, commemorative labels, etc.
