Three kinds of packaging methods that can be carried out by shrink film packaging machine

Shrink film packaging machine is a combination of pneumatic components and mechanical devices, automatic packaging equipment controlled by PLC and other peripheral lines. The actuator of the device is a cylinder. It is controlled by the two-position five-way solenoid valve to advance and retreat. 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 movement of the cylinder. Our company has designed a shrink film packaging machine suitable for our country, and achieved the expected results through debugging and application. The application of the shrink film packaging machine can greatly reduce the material and labor costs of the use of the middle box packaging, and has important economic significance.

1, open ends

It uses a tubular film or a flat film to wrap the packaged product in a sleeve and then heat shrinks. After the package is completed, there is a shrinkage port at both ends of the package.

2, four-sided sealed

The product is wrapped around a flat film or a tubular film, and the joint is sealed by a lap joint. Used for product packaging that requires sealing.

3, one end open

Tray shrink packaging is a typical example. The film is first made into a square bottom bag, and then the big bag is placed on the stacked commodity tray from top to bottom, and then heat-shrinked. Place the tray with the product on the conveyor belt and put on the shrink film bag; the conveyor belt is fed into the heat shrinkable passage, and the shrinkage package is completed after the heat shrinkage passage. Its main feature is that the products can be firmly bundled in a certain number of units, which will not be loose during transportation and can be stacked in the open air.
