Shrink packaging machine

Introduction: Heat shrink Packaging Machine is a machine that wraps a product with a heat shrinkable film and then heats it so that the film shrinks and tightly wraps the product. It can also be called a heat shrinkable film packaging machine or a heat shrinkable film machine.

Shrink packaging machine

The heat shrinkable packaging machine is a machine that wraps a product with a heat shrinkable film and then heats it to shrink the film and then wraps the product tightly. It can also be called a heat shrinkable film packaging machine or a heat shrinkable film machine. The shrink film is wrapped around the outside of the product or package, and the heat shrinks the shrink film around the product or package. Not only can increase product sales, increase the appearance and value, but also reduce the possibility of the product being dismantled and stolen.

working principle

The heat shrink packaging machine is a kind of automatic packaging equipment that combines pneumatic components and mechanical devices and is controlled by PLC and other peripheral circuits. The actuator of this equipment is the cylinder. The two-position five-way solenoid valve controls its forward and backward movements. The working position of the cylinder is detected by the magnetic switch and the 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, thereby controlling the action of the cylinder.

Application area

The use of heat shrink packaging machine can greatly reduce the packaging materials and labor costs, widely used in glass bottles, styrofoam, paper boxes, toys, electronics, electrical appliances, stationery, books, records, hardware tools, daily necessities, medicines, cosmetics, beverages, Fruit, commemorative labels and other items are packaged.


According to the film: can be divided into pe film shrinking machine and pof film shrinking machine;

According to the heating method: it can be divided into quartz tube heating and stainless steel heating;

According to the speed regulation: can be divided into electronic speed control and frequency control.


1, the same as the heat shrinking packaging machine and the winding machine consumes a lot of power, so the power input power must be greater than the nominal power on the shrinking machine nameplate, otherwise it is easy to burn lines or electrical components.

2. Machines like balers must be reliably grounded to protect personal safety.

3. Each machine is shipped with a cable to connect to the power supply. The end of the cable has a power supply identification symbol that must be properly connected. Operation in violation of the regulations may result in electric shock.

4. When the specified voltage of the machine is a three-phase 380V power supply, the neutral line must be input at the same time, that is, the standard three-phase four-wire system other packaging equipment is also like a vacuum packaging machine. Otherwise, the machine will not work properly and it will easily burn internal electrical components.

5, the machine must be installed horizontally, otherwise it will shorten the life of the heating tube. For belt conveyor machines, its tilted installation will cause the conveyor belt to be off-center.

6. When the machine is used continuously for more than three months, the heat-resisting wire of the shrinkage chamber shall be inspected and replaced according to the degree of aging.

7, when the machine works, the operator's palm and other parts are not allowed to contact with the machine's operating position, especially the high temperature inside the shrink chamber, it is easy to burn.

8, after the end of the packaging work, should first turn off the heating switch, so that the transmission motor and fan motor continue to run for about 10 minutes, and then cut off the entire power supply.


1, using far-infrared direct heating 2, the device body size is small, warm-up time is short, power saving 3, electronic continuously variable temperature 4, shrink does not affect the quality of packaged goods can shrink packaging perfect 5, apply to rules or irregular Packaging of items
