Teach you how to identify the quality of sealing tape

Article source:Editor:

Universal packaging sealing tape (BOPP biaxially oriented polypropylene downstream products) is any enterprise, company, personal life indispensable supplies, but how to choose, many consumers understand the tape is that the price is low, feel the viscosity comparison Well, in fact, this is wrong. Tape is based on the BOPP film on the basis of high-pressure corona after a rough surface after the coating of glue after the sub-divided into small rolls is our daily use of the tape, so the first tape depends on the strength of BOPP film is good or bad Thickness, the use of raw materials made of particles BOPP film brightness, flexibility and strong, less impurities black spots, the use of the film made of tape, the general business are not mixed with toner for impurities, so transparent tape finished product is pure white color. Finished products placed around a week after 100 meters below the tape transparency is very high. The thickness of the film is generally between 28 microns and 30 microns, but due to the fact that the BOPP film strength of the partially doped regenerated material is reduced, only the thickness of the thickened film is felt, and the tape feels very thick, but the strength is poor, Period is very short, placed about six months there will be obvious aging, the surface will be brittle, easy to use off. Ordinary sealing tape glue is acrylic glue, also known as pressure-sensitive adhesive, the main component is tincture. Tincture is a kind of macromolecular active substance, the temperature has a certain impact on molecular activity. Glue tincture material directly affect the use of tape, many individuals think that sticky tape is good glue, in fact, this is wrong. Adhesive tape in the use of good or bad there are two standards, one is the initial sticky force, one is to maintain the force, the two are inversely proportional. Generally speaking, the initial adhesion of less than 10 of the tape is coated with glue less, generally only about 20 microns, such as stationery tape, the general promotion of bundled tape. Normal sealing tape of the initial adhesion between 15-20, the thickness of this tape glue generally 22-28 microns. Is in line with the standard thickness. But most of the tape on the market are now mixed with impurities, so the thickness increases, to cover impurities, glue is also mixed with toner, so transparent tape appeared egg yolk, light green, this tape is generally inferior. For colored tapes how to distinguish between good and bad? For the color of the tape is to facilitate the mark and shelter purposes, generally beige and khaki more. Many people think that is the color of the film, in fact, the color is the color of glue. Will be fastened and then quickly opened, you can pull the side of the plastic, you can see the purity and transparency of the original film. The most important thing is to see the thickness of the glue. If there is no glue is opened or point-like pull, this glue is a large number of impurities, glue is not cohesion. Second, too much water, has been volatile, this time the tape has been a strong decline in the beginning of the stick, feel able to distinguish. Will be coated with yellow tape on the object, the better the better the glue, the better the quality. Tape in the appearance of the comparison, the plastic less, doping the tape of the whole volume of the deep color, pull the tape after the high transmittance. Good tape the whole volume of the color and opened after a little color difference, because the good sealing tape has a strong shielding, there is no color superposition of the situation. Dip-doped low-quality tape to impurity on the BOPP film, only the use of relatively backward method of direct glue, so often there will be a large impurity particles are not completely dissolved card knife situation, so the tape in use often There is a place where there is no glue. Good tape with soft cut transfer on the way, there is no line of the situation (printed tape leaks less printed with the press situation). Another way to distinguish is to look at the tape surface, the tape has just passed into the finished product when there are bubbles, put a week after the basic bubble will be dispersed, pure tincture glue tape surface smooth, without any white spots. Adhesive tape with a lot of irregular distribution of the white point, hand pressure does not disperse, is not the same with the bubble. In summary, we have been able to determine the tape from the appearance of the basic can determine the tape is good or bad, and then a good distinction between good and bad tape is the most important condition is not just feel feel viscosity, because the doped tape in the absence of volatile time The initial sticky force is very high, so use the tape to paste the object and then quickly open to see the holding force, repeated paste several times and then touch, the obvious feeling twist decline. Dopant tape for glue when the general use of gasoline and acid to be dissolved, so the smell is very large, regular large enterprises are dissolved in toluene, in the coating process has been volatile after the fan. There is a problem, good or bad tape in the use of what is the difference? In fact, we use the tape is not sticky to live the problem, but to stick solid, not separate. Most of the dopant-containing tapes will now be disintegrated after a period of time (between 20 and 1 hour), and can not be pasted again, especially in low-temperature environments and windy dry conditions Under the more obvious. Again inferior tape easy to break, the intensity is very low, mainly with the quality of the membrane. Formal production of tape paper tube are used high density paper tube, cut paperless paper, and paper tube thickness of 100 meters below the tape is 3 mm, 100 meters above the 4-5 mm, and small businesses for the blind Consumption of thick paper tube, usually the thickness of 5-7 mm thickness, which in the appearance of relatively large, but the glue is very obvious comparison out. So when the choice of tape must see the width of the tape and the thickness of the tape, and note that due to poor quality tape mixed with a large number of impurities, so the coiling when the tape between the perceived gap, so the same number of meters Under the volume of the larger, so blinded consumers.
