  • High Accuracy, High speed, saving labor costs.

  • This machine is equipped with both a weighing system and an infrared optical counting system. It first does automatic bulk feeding gradually, to the point that close to the (weight/quantity per bag) value pre-set. Then the infrared optical counting system does compensate feeding, to achieve accurate packaging. So the finished products in every finished bag are of very high precision in weight/quantity. 

  • It’s designed for pillow pack style, so suitable for a wide range of products. 

  • The film roll device is specially designed as low so it’s convenient for the worker to do film roll replacing

  • 7-inch color touch screen; required parameters such as weight/quantity per bag, bag length, product cumulative count, clear zero, etc. can be set on it. 

  • Mitsubishi PLC control system; The whole process of measurement, bag making, filling, sealing, cutting and counting is done automatically.
