How To Check The Quality Of Foam Tapes
Microland (Shanghai) Limited | Updated: Jun 09, 2017

How to check the quality of Foam Tapes
Today to share with you the quality of Foam Tapes how to check:

   1, check the bubble tape on whether there is crack

   Bubble tape at the time of cutting, if the cutting tool adjustment is not appropriate or blade is not sharp enough, will be in the Foam Tapes or paper on the end of paper cracks, cracks will be pulled out of the fiber sticky adhesive. The occurrence of cracks may be continuous, it may be random, may appear in the roll Foam Tapes side, may also have both sides, so the Foam Tapes on the machine before processing, we must carefully look at the end of paper and tissue paper Whether there is a small crack.

Then, take a sample of the above inspection, stripping the bottom paper again to check whether there is a crack on the paper and the bottom paper, because the crack is sometimes very small, only separated from the end of paper and tissue paper can be found.

   2, check whether the bubble tape edge

   Roll Foam Tapes edge smooth, no damage, is to ensure the quality of Foam Tapes basis, so before processing must carefully check the roll Foam Tapes cutting edge whether there is burr, whether due to improper storage and storage and damage, and to Roll the roll of Foam Tapes for 4-5 turns and carefully check the edge of the cut.

Followed by the above we mentioned the appearance of the bubble tape inspection methods, and today we come to add some knowledge on this aspect.

   3, check the edge of the bubble tape adhesion, the end of the paper is leaked silicon

   Foam Tapes edge adhesion or the end of the paper part of the leakage of silicone oil, in the processing process will cause waste when the paper broke, can not be normal production. Therefore, the processing should take a length of about 1 meters before the adhesive material, hand stripped to see whether the edge or other parts can not smooth the same part of the peel. Typically, the edge of the paper and the end of the paper edge of the adhesive occurred in the entire volume of the adhesive material coated on a slitting volume, and generally only occurred in the outer 7 meters to 10 meters, so, Foam Tapes edge adhesion, do not immediately assert that the whole roll paper has this problem.

In addition, it is important to note that stripping of light weight paper (such as 60 g / m2 and 80 g / m2 of tissue paper) is greater than the force used to peel the weight of the tissue paper, the lighter the paper, the more tight feel when stripping. It is precisely because of this, sometimes according to the shape of the customer to die to cut the customer selected Foam Tapes, can not be completed in the conventional processing speed.

   4, check the reel Foam Tapes cut the end face is straight, rewinding elastic is consistent

If the roll of Foam Tapes cut off the end of the face, not only will affect the processing of the registration, but also due to changes in die cutting position and the occurrence of waste discharge difficulties; rewinding loose inconsistency will lead to changes in paper pressure during printing, Uneven tension also causes print quality problems.
