The middle of the 4 mm (4000 microns) thickness of a few laps and we wound is 4000 ÷ 50 = 80 laps. That is how much tape do? 0.27 × 80 = 21.60 meters which is very easy to compare the big paper tubes for consumers is favorable or unfavorable. If it is a tape width of 6 cm, for consumers, that is 21.6 m 0.06 × 21.6 = 1.296 square meters, according to the current tape cost prices 0.88 yuan / square meter, which means that every consumer tape roll in pay 1.14 yuan, for an enterprise ,, this is a great long-term consumption of loopholes.
In fact, think about everything very simple, paper tube is made of a material, the more the thicker the material used, the higher the value, of course, cheaper than tape (paper tube every 1 mm thick, price increase 0.4-0.6 yuan per meter, many of my friends may see nothing, the 1-meter-long paper tube 7 mm to about 1.6 yuan more than 1 meter long 3 mm paper tube. now companies are generally 45 mm wide tape generally each containing 60 volumes, that is 2.7 meters, is equivalent to RMB 4.32 per case, compared to the cost of this lack of tape that is a good deal, but as consumers, who pay for this cost I do not think say) tape production enterprises as to choose higher costs, of course, there is a purpose, but not all of the tape can be with a small paper tube, generally more than 200 meters will use a 4 mm tape thickness pure when 2 centimeters, because the tape, the greater the pressure on the paper tube, so to increase the intensity, if we find that more than 5 mm of paper tape on the market, basically you can not choose, because the thicker, artificial packaging more convenient time. Especially a lot of companies use tape cutter for packaging, since the paper tube is too thick and cause actual tape reduced, thereby increasing the cost of packaging. VI.
