Although China adhesive tape industry has great development, but compared with advanced countries in terms of quality, there is still a large gap and the ordinary sealing packing tape two-way stretch polypropylene (BOPP) tape is any enterprise, company, personal life indispensable things, due to its technical content is not high, many domestic manufacturers, so the products on the market is uneven. And our domestic adhesive tape industry still stay on phase of low technical content, country of tape is not a perfect standard.A lot of consumer understanding of adhesive tape is is that the price is low, feel is viscosity is better, in fact, this is wrong. Tape is on the basis of the original film BOPP after high voltage corona makes a rough surface cladding coating glue after after article points into small volume is our daily use of tape, so first depends on the strength of the adhesive tape BOPP film quality and thickness of the particles of raw materials manufacturing BOPP film brightness is good, strong flexibility, less impurity black spots, the film made by tape, enterprises are generally not adding toner for impurity covered, so transparent adhesive tape products are pure white color. Finished product placed 100 meters below the tape after a week or so transparency is very high.General membrane thickness between 28 micron - 30 microns, but due to some doping the reworked material of BOPP film strength drops, so only with thick membrane thickness of this tape feels feel is very thick, but the strength is poor, short shelf life, placed about half a year will appear obvious aging condition, the surface will be brittle, use easily
