Performance advantages of all plastic square bottom valve pockets used in cement packaging

2023-09-11

The all-plastic square bottom valve bag can effectively improve the quality of cement, and it has the performance of anti-fall, anti-leakage, moisture-proof and so on. With the deepening of the industrial automation process of cement enterprises and the further attention to the quality of Cement Bags, the quality and performance requirements of cement valve bags are becoming higher and higher.


It is mainly manifested in: mechanical properties, that is, strong and strong, anti-wrestling, and able to cope with long-distance transportation. Such as moisture resistance and good sealing, ensure that the product will not be damp during storage and transportation, the product will not leak, and will not cause cement loss. In terms of automation function, it can be filled efficiently, quickly and accurately.

At present, the all-plastic square bottom valve bag has been widely used in cement enterprises at home and abroad, which is characterized by fast filling, neat and beautiful, good sealing, fine printing, large storage, and standing packaging, which is very suitable for stacking and transportation operations. With the automatic filling of the packaging machinery, the valve port on the top can achieve the effect of automatic sealing after the cement is filled, saving time and effort.


The all-plastic square bottom valve bag is produced by the special square bottom valve bag bag making machine. A low-cost square bottom valve bag suitable for automatic packaging is manufactured using a pp woven bag tube with a film covering and processed by the heat seal production process. The upper and lower sealing of the square bottom valve bag does not require any sewing thread. Instead, the braided fabric coating is used for stable thermal bonding.


The coating of the bottom of the bag and the coating of the valve orifice and the bottom sealing plate are softened by hot air and then heat-sealed together by pressure. The square bottom valve bag production line changes four separate production and processing processes such as cutting, printing, valve opening and sewing, improving production efficiency and product quality, and saving a lot of manpower and materials.


There is no sewing in the production process, which not only reduces the production process, but also saves the sewing thread and the brown paper seam. Fundamentally avoid the stitching head and paper edge into the cement concrete, ensure the construction quality, and keep the site environment clean. It is conducive to the recycling of packaging bags after use and the protection of ecological environment.


Using the latest punching method, microhole punching technology, the hole diameter is small, the hole density is large, the aperture and density can be adjusted according to the can exhaust, reduce the problem of excessive strength loss caused by punching. In the process of filling and transportation, it greatly reduces the phenomenon of ash spraying and ash leakage, improves the filling site and the loading and transportation environment, reduces the loss and waste of cement, and meets the development requirements of energy saving and environmental protection.


The square bottom valve bag packaging cement, so that the bag after filling is square, improve the stacking shape, can improve the product packaging level, good appearance image and quality, and is conducive to expanding the market influence of China's cement products. The most important thing is that cement enterprises realize cement filling, stacking, storage, loading and transportation processes are automated mechanical operations, which can reduce a lot of human resources and save expenditure costs.
