Polypropylene twine is in great demand in the packaging materials market. What is this product and what is it used for? Let's try to understand this issue.

Polypropylene twine - what is it?

This product is a polypropylene, technical, film thread. It is made by twisting. Polypropylene twine is wound on a special bobbin without a sleeve.

Polypropylene material belongs to the class of polyolefins. It is an environmentally friendly product, completely safe for human he alth and the environment. Therefore, polypropylene twine will also not do harm. How is it made?

Production of polypropylene twine

This process takes place in several stages:

1. The raw material - polypropylene - is fed into the storage hopper.
2. From this section, the ready-made granulate enters the drying compartment. The temperature here is regulated from 60 to 110 degrees Celsius.
3. Then the raw material goes back to the storage hopper, then to the extruder.
4. Here the polymer is melted, filtered, then fed to the extruder mold head.
5. In the form of a film web, the material enters the cooling drum. Here it solidifies.
6. Then the film is cut into ribbons.
7. Next, the process of pulling the tapes in the orientation chamber is carried out. This is due to the difference in speeds of the second and first seven-rollers in an environment of sufficiently hot air (the temperature in the orientation chamber is at least 150 and maximum 210 degrees Celsius).
8. The film tape on the fibrillator forms threads of a mesh structure. Then it is wound on bobbins.

Product Application

Polypropylene twine is actively used in the following industries:

• agriculture;
• meat processing industry;
• for the production of ropes with different diameters;
• for household packaging.

In certain applications, the above products have technical advantages. Farmers prefer to bind bales of straw with this packing thread. Experts note that the person who began to use polypropylene twine is unlikely to ever return to sisal.

Product Benefits

Polypropylene twine has the following features:

• high resistance to alkalis and acids;
• has excellent thermal insulation properties;
• unaffected by organic fertilizers;
• enougheconomical material;
• completely safe and environmentally friendly;
• increases productivity;
• safe to use (for example, steel or galvanized wire can hurt human hands);
• significantly reduces the price of packaging.

In addition, this packaging material does not rot and has high fibrillation. It is very easy to handle. Although, as experts note, this polypropylene thread has one drawback. It breaks down when exposed to sunlight. But such an impact must be lasting. However, if special components were added to the composition of the above packaging material during the production of the above packaging material, which increase the durability and light fastness, this problem is eliminated.

Another advantage of polypropylene thread is its high buoyancy. It is also resistant to bending and abrasion. It is an excellent dielectric, very convenient for lacing and tying.

Polypropylene twine, the price of which is 60% less than the cost of a metal thread, depending on the type, can be bought for 105-300 rubles. per kilo.

This product is an excellent packaging material. The excellent technical characteristics of the polypropylene thread contribute to the high demand for it.
