High-Precision Automatic Weighing and Packaging Machine

  • Air pressure 0.4-0.8 Mpa
  • Electric voltage 220V 50Hz / 60Hz
  • Power 3.5 KW
  • Capacity 5-50 pakge / min
  • Applicable Packaging Materials OPP / CPP / PE etc. Heat-Sealable Laminated Film

This weighing and packaging machine is specifically engineered for automated packaging environments where strict weight accuracy is paramount. At its core, the machine features a high-precision weighing module that performs accurate packaging based on the actual measured weight of each product.

For heavier materials, the machine incorporates a specialized bottom support structure designed to cushion the impact as material drops — ensuring the packaging bag retains its shape and remains free from deformation even under heavy load.

Highly versatile and compatible with a wide range of common heat-sealable composite films including OPP, CPP and PE. Bag length can be adjusted directly via the display screen or precisely controlled using a photoelectric sensor to track print marks for accurate cutting. Ideally suited for hardware accessories (metal clips, washers, fasteners) and various loose granular materials.
