Troubleshooting Creasing Issues – Solutions from Kenray Forming

 

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.
So there you have a short video on creasing. I hope you found that useful. If you need more information, please either visit our website or give us a call on +44 (0)1530 400 100 or email perform@kenrayglobal.com

Thank you very much.

Kenray Film Snapping Troubleshooting Solutions

 

So in this short video, I’d like to talk to you a little bit about film snapping and what causes it?

The film can snap for a number of reasons. Usually, it’s because there’s too much tension.

This could be the result of poor geometry on the shoulder. It could also be because the tube is too close to the shoulder which you can see here. You can see the film is actually peeling rather than ripping.

Sharp edges or the crossover point being too close could also be a key cause of film ripping.

Here you can see the film actually ripped because the gap between the shoulder and the tube is too tight.

So there you have a short video on film snapping. I hope you found that useful. If you need more information, please either visit our website or give us a call on +44 (0)1530 400 100 or email perform@kenrayglobal.com

Thank you very much.
