Today, I’d like to talk to you a little bit about open back seals and the things that cause them. One of the reasons for the open back seal is that the former is not correctly positioned on the machine as seen on the video above.
You can see that demonstrated. Another reason for the open-back seal could be the tube alignment, in this example, you can see that the tube is offset left to right and in this scenario, the tube is offset front to back.
Another reason for the bag opening up could be the geometry of the shoulder which may be incorrect or the crossover point may be in the wrong position. This is an example of a shoulder where the patterns have been predetermined by forward-engineered models. It will require testing, but this will be minimal.
So here you have a little insight into open back seals to find out more or to let us help you fix some of the problems you may have please either give us a call or visit our website.
Thank you for watching.
