BOPP packing tape
Packaging tape history:
In 1928, Scotch tape Richard Lu, of St. Paul, Minnesota, applied for the application in the United Kingdom and the United States on May 30, 1928. Drew developed a very light, compact adhesive, and the initial attempt was insufficient. Sticky, so Drew was told: "Take this thing back to your Scottish bosses and ask them to put more glue!" "Lan" means "hey," but during the Great Depression, people used this tape. Hundreds of uses were found, from dressing up to protecting broken eggs.
Packaging tape principle:
Why can packaging tape stick? Of course because it is coated with a layer of adhesive on the surface! The earliest adhesives came from animals and plants. In the 19th century, rubber was the main ingredient of adhesives; modern polymers are widely used. Adhesives can stick to things because of the formation of bonds between their molecules and the molecules that they are attached to, which bonds the molecules firmly together. Adhesive ingredients, according to different brands, different types, there are a variety of different polymers.
