Common packing tape glue is acrylic resin glue, also called pressure-sensitive adhesive, was mostly fat tincture. Tincture of fat is a kind of polymer material, temperature had certain influence on molecular activity. Glue the tincture of fat content directly affects the usage of duct tape, many individuals think feel sticky tape to glue, actually this is wrong. Tape glue is good or not in use, there are two standards, one is the initial moisture, one is the retention, is inversely proportional to both. Generally in the viscous force of less than 10 less glue tape is accordance with teaching, generally only about 20 microns, such as stationery adhesive tape, ordinary promotional bundled with the tape. Normal packing tape at the beginning of the viscous force in 15 Between 20, generally speaking, there are 22 - the tape glue thickness 28 micron. The thickness is standard. But most of the tape on the market at present is mixed with the impurities, so the thickness increase, the impurities to cover, the glue is mixed with the pigments, so transparent tape will appear the egg yellow, light green, this tape is generally inferior.
