We buy sealing tape, double-sided adhesive, many people will like to buy other products, the price is certainly high, it is not true, the tape is a tool supplies, is a certain professional, different products paste With different tape, the quality of the tape depends on the raw material it uses, ie, the film and glue.
We often use the tape products produced by the original film is BOPP material, the tape is in the BOPP original film on the basis of high-pressure corona after a rough surface after the coating of glue after the sub-divided into a small volume is our The strength of the tape depends on the BOPP film is good or bad and thickness, the use of raw materials, BOPP film made of good brightness, flexibility, and less impurity black spots, the use of the film produced by the tape, the general business are not Mixed with toner for impurities, so transparent tape products are 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 because of the decrease in the BOPP film strength of the partially doped regenerated material, 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 will appear 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 ingredient is tincture. Tincture is a kind of macromolecular active substance, the temperature has a certain impact on molecular activity. Glue tincture content directly affects 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 glue coated teach less, generally only about 20 microns, such as stationery tape, ordinary promotional 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 also mixed with toner, so transparent tape appeared egg yolk, light green, this tape is generally poor.
Understand the quality of the tape factors, at the time of purchase, do not make the price to determine the quality of the error, the most important thing is to buy the appropriate product. In the purchase of sealing tape, consumers can look at these two aspects of the quality of tape.
