We have a Laundry Powder Packaging Machine, which fills and packs laundry powder packets of 250g, 450g, and 500g.
Now that we have changed to a different supplier of cardboard packages, the machine can not pack the new packets perfectly as compared to the old onces (from original supplier). The new packets are a bit thicker than the old packets though they have similar dimensions.
we have done all the necessary adjustments of centre fold (flap) tuckers and side or end rail tuckers, but are not getting a good finish on the packets.
As a result we are still having leakages from the bottom of the packets as the folding and sealing are a bit off squared, not aligned for a perfect bottom seal.
Our fitters and I have made several redesigns of end tuckers butt are still having poor sealing at the bottom of the packet. The sealing temperature is good, the problem lies in the folding of the packets flaps.
How can we get the bottom packet folds (flaps) to perfectly fold in for a perfect sealing?
