A story of pouch filling process – Chemical Packaging

Today’s machine has a speed of 400 milliseconds, and in the case of horizontal form fill and seal (HFFS) pouching filling machines, the entire high-precision process of filling has to occur within a short time frame.

The key is to have a strong understanding of the product to be capable of managing its flow into the bag with the most accurate dosing. Various parameters require to be brought into consideration to establish the correct filling technology and achieve the best results.

As a specialist of their product, the product owner requires to share their product information with machines manufacturers. So, more info with the machine manufacturer understands about the product & it makes it more assure the correct technology selection, i.e., consistent flow properties and precise.

If it is powdery products, many various features run together to control which type of dosing machine is needed as well as its performance. 

These varieties from granulometry and uniformity of product size, fluidity, density, and hygroscopic characteristics.

How dosing accuracy works

Generally, powders are filled in pouch by utilizing an auger filler, which is a dispenser that continuously delivers a pre-set volume of product. The dosage can be measured electronically by regulating the precise amount of times the auger screw turns per cycle. By this kind of fillers regulate the amount of product per dose by volume and not by weight, the granular properties, therefore, influence the accuracy of filling.

To achieve efficiency, the first rule is to assure you are working within a stable environment. In other words, it is necessary to ensure there is a consistently stable quantity of a product in the hopper of the dosing machine. The feeding system sync with the auger filler, which has particular detectors that can measure the level of product being carried inside.

The size of the product is fundamental for product character as well. The product stirrer, the auger tooling, the interference of the screw, and the tube require to be created to ensure no gap of the particles.

It is well seen in food and chemical packaging companies, like masala packing, washing powder, etc.

Chemical packaging is required high skill to this type of filling because the product changes their nature with some environmental change and the handling of that product is very typical.
