3. Check if the edges of the double-sided tape are stuck, and if the bottom paper is missing silicon
If the edges of the double-sided adhesive tape are stuck or the backing paper is partially coated with silicone oil, it will cause the paper to break during the waste discharge process, which will prevent normal production.
Therefore, before processing, take a length of about 1 meter of self-adhesive material and peel it off by hand to see if there is any part that cannot be peeled smoothly and consistently on the edge or other parts.
Usually, the edge adhesion between the face paper and the bottom paper occurs on a slit roll of the entire roll of coated self-adhesive material, and generally only occurs at the outer layer of 7 meters to 10 meters, so when you encounter a slit roll There is adhesion on the edge of the double-sided tape.
Don’t immediately assert that the entire roll of paper has this problem.
In addition, it should be noted that peeling light-weight facial paper (such as 60g/m2 and 80g/m2 facial paper) is stronger than peeling heavy-weight facial paper. The lighter the facial paper, the tighter the hand feel during peeling.
Because of this, sometimes when die-cutting the double-sided tape selected by the customer according to the shape required by the customer, it cannot be completed at the normal processing speed.
