Tallpack International develops perfect packaging solution for very fine, air-entrained powders

Tallpack has worked with a customer to develop effective 10kg to 25kg packaging for very fine, moisture-sensitive and air-entrained powders. The main challenge involved finding a controlled way to allow large amounts of air to escape from “inside” the powder during the filling process. Air escapes from the concerned powders extremely slowly, which can present issues during transport.

When such bags are palletised, they present a risk for pallet stability during storage and transport. The intensive development process was started because regular ventilation openings in existing bags were too big for very fine powders and resulted in powder loss.

High-tech bag:
High-tech features have been used to modify the ventilation openings and properties of the bag so air can now escape in a controlled manner. Things have been speeded up so much that bags can now be palletised immediately after the bagging process. This helps to significantly improve pallet stability.

The FFS bagging machine:
The FFS (Form-Fill-Seal) bagging machine weighs and doses the product; this is done with a screw/weigh system and a screw which enters the bag vertically and starts filling from the bottom. The bottom of the bag is shaken by an adjustable shaker during the filling process, so the product is firmly compacted; this improves the bag’s filling capacity. By puffing out the seal before welding, one is able to get a perfectly closed FFS bag. The machine is able to fill bags with up to 50 kg of product.

Tallpack International is able to offer the whole process – from weighing, filling, labelling, palletising, wrapping and stretch hooding of pallets – as a turn-key solution. This means customers have a single point of contact when establishing and maintaining the whole line. A single supplier means everything is quickly available and that service can be planned effectively.
