ZWG-210 Automatic Heat-Shrink Packaging Machine

ZWG-210 Automatic Heat-Shrink Packaging Machine

The ZWG-210 Automatic Heat-Shrink Packaging Machine is used for primary film packaging of finished kitchen towel rolls and other compatible household paper roll products. The machine combines product feeding, film feeding, sealing and cutting with a heat-shrink tunnel to form compact retail packs.

This is an individual packaging machine rather than a complete kitchen towel production line. The finished rolls must first be produced by a rewinding machine and cut to the required width by a log saw or another compatible cutting machine.

Suitable Finished Products

• Finished kitchen towel rolls with paper cores

• Compatible household paper rolls within the confirmed size range

• Single-roll or arranged multi-roll packs supported by the approved feeding and film configuration

Packaging Process

Finished rolls enter the feeding section in the required orientation. The machine feeds the packaging film, tracks the sealing and cutting position, and forms the initial film package around the product. The sealed pack then passes through the dual-temperature-zone shrink tunnel, where hot-air circulation shrinks the film around the arranged rolls. The completed pack is discharged for inspection, collection or connection to downstream handling equipment.

Control and Packaging Material

The documented configuration uses three-servo control, a color touch screen and high-sensitivity photoelectric tracking. Bag length, operating speed and temperature can be adjusted according to the confirmed product and film. PVC or POF film is listed for the documented configuration. Film samples should be tested before continuous production, especially when printed film, unusual thickness or several package sizes are required.

Reference Operating Range

The documented packaging speed is approximately 30 to 100 packs per minute. Applicable package length is approximately 60 to 300 mm and package width is approximately 80 to 130 mm. Practical output depends on roll dimensions, pack arrangement, film, sealing conditions, shrink settings and upstream product feeding.

Information Required for Configuration

• Finished roll diameter and width

• Core or coreless roll structure

• Number and arrangement of rolls per pack

• Required package length, width and height

• Film type, thickness, width and printed-mark requirement

• Required packs per minute

• Upstream cutting and conveying arrangement

• Destination voltage and frequency

• Available workshop dimensions and material-flow direction

Configuration Note

The listed values are references from the documented ZWG-210 configuration. Final operating range, installed power, package format and equipment interface must be confirmed in the approved technical agreement and layout.
