Why choose us?
1.High precision intelligent temperature control system
It adopts a patented temperature control unit to ensure that the heat-sealing temperature remains stable all the time, avoiding heat attenuation caused by long - term operation and effectively improving the sealing quality. It supports a film thickness of 30 - 150μm and is suitable for medical - grade PE/PET materials and industrial composite films.
2.Dynamic Bag Length Detection Technology
Equipped with an intelligent sensor inside, it can automatically identify the bag length without pre - printed marks. It supports the detection of continuous unmarked bags, breaks through the bag length limitations of traditional models, and is compatible with multiple materials such as PE, kraft paper, and aluminum foil.
3.Triple Anti - Misoperation Design
Mechanical Interlock Device: Automatically locks when there is no foreign object in the sealing area to prevent mis - startup (patented technology).
Light Curtain Monitoring: The infrared light curtain continuously monitors the sealing area to avoid the risk of pinching (CE - certified).
Zero - Pressure Sealing: The magnetic levitation drive technology enables gentle closing, extending the service life of the equipment.
