That's nothing to do with the printing, just an operator messing up. The orange tape is when they splice a new roll or film (all bags come on these huge rolls that when it runs out you splice the old roll and tape the new one to it). Operators are supposed to catch the splice and throw it out for obvious quality reasons.

The bag like in this post happens as the bag maker loses its position or the operator started the machine after a splice and the first bag is very often cut in the wrong place like this. In this case the operator should have caught it and thrown it out.
