guide language: the tape is often use to our daily life. Adhesive tape was first invented by American scientists Richard lu. Until today in development of tape is already very mature, this project by small make up for all detailed knowledge on the tape.
1。 Tape profile
in 1928 in saint Paul, Minnesota, Richard & middot; Drew invented the scotch tape. Tape according to his functions can be divided into: high temperature tape, double-sided tape, electrical tape, special adhesive, pressure sensitive adhesive tape and die-cutting adhesive tape, the effect of different for different industry demand. Adhesive tape on the surface coated with a layer of adhesive to make the tape stick to items, one of the earliest adhesive from animals and plants, in the 19th century, rubber adhesive is the main ingredients; While modern widely used all kinds of polymer.
2。 Tape specifications
Jumbo Roll, volume, the machine is prototype tape, width of 1 m to 1. 5 meters, the length from a few hundred meters to thousands of meters, depending on the different substrate.
the Log Roll, big volume, namely the mother Roll products after rewinding, width, length varies according to the requirements ( General is 100 meters, 50 meters, 25 meters, 10 meters, 5 meters) 。
Slit Roll, small volume, Finished product volume) The general products on the market. 【 Detailed & gt;> 】
3。 Tape classification
according to the division base material: can be divided into the BOPP tape, duct tape, kraft paper tape, textured paper tape, fiber tape, PVC tape, PE foam tape, etc.
division: according to the scope of the application can be divided into the warning tape, carpet tape, electrical tape, protective film paper glue, stretch film, adhesive tape, sealing tape, modules, tape, etc.
according to the division market penetration: can be divided into ordinary tape, special tape.
according to the application environment temperature classification: can be divided into low temperature tape, tape, high temperature tape at room temperature.
4。 Duct-taped to choose
1, the smell in low temperature environment, basic stick on the carton will craze, smell the strong early feel when viscous force is very sticky, but will soon dry rubber surface, loss of gum, that time in the tape surface has crack. Because of the gelatinize unevenness of
2, see the brightness of the membrane, inferior adhesive tape are usually dark color, this kind of tape fracture probability is very high, intensity difference.
3, touch membrane thickness, feel hard membrane adhesive tape is generally more times, and as the film thickness, the actual number of meters will be reduced. Good tape chooses membrane are soft, good tensile staying power by hand.
4, see color, general appearance color more white transparent tape, adhesive tape impurity is less, to guarantee the normal adhesiveness, 100 meters below the tape has certain transparency can see paper tube. Surface had yellow tape the tape distribution of irregular white point, pressure by hand wipe not to go for impurities or glue dry imprinting, this product is generally with a smell.
5, the paper tube: use thick paper tube adhesive tape is usually to misdirect consumer.
