Why is the valve pocket more favored by building materials and chemical enterprises?

For building materials and chemical powder products, the valve bag is firm and strong, and can cope with bumps and individual rough loading and unloading methods during long distance transportation; In terms of use performance, it is moisture-proof and sealed to ensure that the product will not be damp during storage and transportation, and the product will not leak. In terms of automation function, it can be filled efficiently, quickly and accurately.

In summary, with such performance, valve bags have been widely used at home and abroad. Mainly used for cement, putty powder, lime, gypsum, grain, fertilizer, chemical raw materials, chemical powder and other product packaging.

The sealing performance of the bag body of the valve bag is good. First of all, the production process of the valve bag requires the use of a bag barrel with a film, to ensure the sealing of the bag body; Secondly, in the process of processing, there is no needle on the bag body, and the sealing of the bag body is also maintained. In contrast, after the ordinary seam bottom packaging bag is filled, powder products are easy to leak out from the seam.

The valve bag automatically closes after the material is filled, and no manual sewing is required. The pictures and pictures printed on the side and bottom of the valve are clearly visible. The bag body is smooth and beautiful, and there is no mucilage of adhesive. The valve bag can be equipped with a double-roll micro-hole device. When the cement, putty powder and other powder products are filled at high speed, the fine micro-holes can ensure that the air in the bag can be quickly discharged to achieve high efficiency filling.

And because of the fine microhole, coupled with the configuration of two-way microhole roller, can avoid the leakage of powder filling, but also can achieve a good waterproof and moisture-proof effect. After the material is filled, the bag body is cuboid brick shape, the palletizing is orderly, the stacking layer is high, easy to transport, easy to mechanized loading and unloading and storage.

The bag valve can be used for manual bag insertion, but also for automatic bag insertion mechanized line filling, even in the filling of cement such a demanding powder material, the automatic bag filling machine speed can reach 5600 bags/hour, greatly improving the production efficiency.

valve bags are widely used in the packaging of cement, putty powder, lime, gypsum, grain, fertilizer, chemical raw materials, chemical powder and other powder products, and are the most used powder packaging bags in today's society.
