Currently, packaging scales on the market are mainly divided into two types: two-level and three-level quantitative packaging scales. The two-level quantitative packaging scale is an early product. With the increasing demand for accuracy from customers, the three-level quantitative packaging scale has emerged (its advantages are not elaborated upon), and it is gradually replacing the two-level quantitative packaging scale.

Selection Principles for Quantitative Packaging Scales: When choosing a packaging scale, first understand the material, characteristics, packaging weight, speed, and accuracy of the item to be packaged; secondly, consider installation parameters such as height, width, operational direction, and cost-effectiveness.
