Easy-tear tape sets a perforated line at intervals, such a design makes the product easier to be torn off neatly without assistance of other tools. Meanwhile the rational distance between each perforated line guarantee the adhesive ability of the product. Behind each perforated line ( new start of next piece of tape), there is a narrow part without gumminess; this design allows people to simply find the start of tape, because it does not stick to tape reel and does not affect the normal use.
