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.

Thank you very much.
