Writable kraft tape introduced that ,Have you ever used paper tape? Why is it easy to peel the tape off the reel, but once it's on the paper, it sticks tightly?
 
It turns out that there are agents on both sides of the tape, one side is the stripper that can easily separate the tape, and the other side is the adhesive, which is the secret of the tape production.
 
In addition, the tape looks like transparent plastic, but it is actually made of wood chips, cotton, linen, grass and other raw materials, which is unexpected. How is the tape making process? Let's have a look.

The first step is to make adhesive paper stock

1. Make pulp (the product obtained from the processing of plant fibers such as wood, rattan and grass), and then add chemicals to fully mix;
 
2. Stir the pulp like porridge, and then place it for a while;
 
3. Add carbon dioxide or caustic soda to dissolve the pulp again;
 
4. After filtration, the raw slurry for making the adhesive paper is obtained.
 
Step 2: making adhesive paper
 
1. Press the raw pulp into thin strips;
 
2. Coagulate the original slurry with coagulant;
 
3. Put the original pulp into bleach and softener, and then wash it with water;
 
4. Roll up the film after drying.

Step 3 apply stripping agent and primer
 
Apply stripping agent on the top of the adhesive paper, primer on the bottom, and then roll it up again.
 
Step 4 apply adhesive
 
1. Apply adhesive on the side of the adhesive paper that has been applied with primer, and then roll it up;
2. Dry the tape.
 
Step 5 cutting
 
Roll the dried tape into a large roll, then rewind it to the required length, and then cut it into the required width.
 
Step 6 packing

Put the cut tape into the box, and the transparent tape is finished.
 
Tips: tape was invented by Americans
 
writable kraft paper tape was invented by Americans in 1930. It originated from the protective tape used for painting cars (paper tape used to cover parts that do not need color or paint when painting).
At first, adhesive tape was used to pack goods. Later, transparent and strong adhesive tape was widely used to repair books or broken glass. Gradually, adhesive tape became an indispensable daily product for families and workplaces.
