So it is a short presentation would like to talk to you a little bit about bag creasing.
One of the reasons for creasing is the age of the shoulder, as the shoulder becomes older, it gets worn by the film as it’s constantly going over the lip. This causes what we call sharks teeth the shark’s teeth that we just described causes the film to rock up as it goes over the lip, this, in turn, causes jagged lines to form down the bag.
Another cause of creasing is when the tube is too close to the shoulder and causes the film to pinch. You can see the consequences of that on the slide shown.
Another cause of creasing can be the role of position which is incorrect and too far back here. You can see that as a consequence of the incorrect role of position. We have creasing on the outside of the bag, which looks like a herringbone
shape and also on the inside of the bag.
So there you can see. Creasing is not only a problem for exterior marks on the bag, but it also breaks the seal inside, and this, in turn, reduces the product shelf life.
Thank you very much.
