WE SELL SCOTCH TAPE AND STRETCH FILM
STORY OF SCOTCH TAPE CREATING
In 1923 Richard Drew started working as a laboratory technician in Minnesota Mining and Manufacturing company (now it is called 3M), that produced sandpaper. This company was researching waterproof surfaces and conducting experiments with cellophane.
Drew controlled product testing 3M's Wetordry brand sandpaper at a local auto shops and body shops. Once in the body shop he saw the auto being painted into two or more colors and noticed how inaccurate the dividing lines were. He promised auto painter to think how to solve the problem and invent something. Richard Drew tested sticky tape 5 meters wide in 1925 in the body shop. Auto painter decided to use sample making tape, but when he started painting the tape started shrinking. After he had examined the tape he understood that the tape had adhesive only on the sides. He told Drew to take the tape back and to put more adhesive on it.
In 1929 Drew ordered 90 meters of cellophane. While testing the tape he had to solve plenty of problems, for example, how to lay adhesive on the tape evenly. On the 8th of September 1930 sample of the tape was sent to be tested to Chicago. Originally scotch was used to pack the package for food. Then during the Great Depression people invented plenty of methods how to use scotch. In 1932 John Borden improved scotch by adding to the dispenser built-in cutter blade. In spite of its name scotch wasn’t invented in Scotland or by Scottish. Originally adhesive was only on the tape sides. Americans called this tape “scotch” because of famous Scottish stinginess. In a while appeared different types of scotch. Besides of invisible scotch tape there are many colored modifications of scotch. Today people usually use standard scotch rolls 5 mm wide and there is also the roll 1 sm wide. There was also invented double sided tape sticky on both sides. Big manufecturers and sellers use scotch with their firm logo on it to pack their products.
Stretch film is used as a transportation packaging in almost all production fields. The film is usually used by milk and alcohol manufacturers but also by producers of building materials and paper and in other production fields. For example, it‘s irreplaceable for packing goods in the storages. To produce high pressure polyethylene film producers used blowing method, which preserves basic technological parameters. It protects loads by its strong fixation as in the process of stretching the film emerges the particular “resistant” force due to the film “memory” that wants to take its starting position. There is no need in special equipment to pack loads using stretch film. It’s economical, strong and easy to use. The load packed into the stretch film can be transported over long distances from the producer to the custom. This modern packaging corresponds today’s firm standards. Modern technologies make packaging very simple. The main characteristics of the stretch film that determines its consumer properties are:
tightening force, that ensure reliable and secure paletising due to the final pressure in the film;
pre-stretching it’s a length the film is stretched to cover the palet without any damage and the length allowes to bound the load tightly; pre-stretching makes machine packing more economical in comparison with the hand packing;
stickiness – guarantees safe transportation and load storing, the load bonded with the film to the palet; besides that load can be easily unloaded;
tear resistance makes the film flexible, makes it resistant to cuts and punctures, saves the load from damages and pollution;
transparency of the packing material makes it easy to control the essence of the load, makes it better to look at that is good for the company image;
low rigidity provides packages flexibility that at the same time can withstand the passage through palet packaging machines;
operating temperature regime – this film capacity makes it strong enough to withstand high and low temperatures and stay sticky;
coefficients of friction provides film slipping in the palet packaging machine, storages of packets at each other without sticking, that’s why the coefficient must be high;
