Will double face adhesive affect its stickiness in summer?
Quality inspection of double sided adhesive tape:1, check whether there is a crack on the double-sided adhesive tapeDouble sided tape in slitting, if the cutting tool adjustment is inappropriate or the blade is not sharp, will be in the double adhesive tape on the surface or bottom paper cracks, cracks at the pull out of the fiber will be adhesive stick. The occurrence of cracks may be continuous, may also be random, may appear in the side of the double-sided tape reel, may also be on both sides, so, double-sided tape processing, not to look carefully at the end of the paper and paper on whether there is a small crack.Then, take a piece of paper that has been checked, peel it off the bottom, and check again whether there is a crack on the bottom and the bottom of the paper, because the crack is sometimes very small and can only be found after separating the base paper and the tissue.
Check whether the double adhesive tape has burrsDouble sided tape reel edge smooth, no damage, is to ensure that the basis of double-sided tape quality so we must carefully check the drum double-sided tape before machining cutting edge or edges, whether due to improper storage damage occurred, and will roll 4 - 5 double-sided tape roll ring, carefully check the cutting edge.Immediately following the aforementioned examination of the appearance and quality of the double sided tapes, we would like to add some more information about this area today.
Check whether the edges of the double adhesive tape are adhered or not, and whether or not the bottom sheet is leaking of siliconDouble adhesive tape edge adhesion or some parts of the bottom sheet leakage of silicone oil, in the processing process will cause waste paper rupture, can not be normal production. Therefore, before processing, take a length of about 1 meters of self-adhesive materials, hand peeling, to see whether the edge or other parts of the smooth, uniform peeling of the parts. Usually, paper and paper edge bottom adhesion occurred in a roll coating adhesive material cutting volume, and generally occurs only in the outer layer of 7 meters to 10 meters, so the drum encountered double-sided tape cutting edge with adhesion, don't immediately assert that the whole roll of paper have this problem.Also note that stripping light weight tissues (such as 60g/m2 and 80g/m2 facial tissue) is more powerful than peeling off heavy paper, and the lighter the paper, the more tightly it feels. Because of this, sometimes, according to the customer's request to cut the shape of the customer's choice of double-sided tape, can not be completed at the regular processing speed.
