Performance and Advantages of Cement Packaging Bag (Plastic Woven Square Bottom Valve Bag)

1、 Performance introduction of plastic woven square bottom valve pocket

The plastic woven square bottom valve pocket can effectively improve the quality of cement, and it has the properties of resistance to falling, leakage and moisture. With the continuous deepening of the industrial automation process of cement enterprises and the further attention paid to the quality of cement packaging bags, the requirements for the quality and performance of plastic woven square bottom valve port cement bags are becoming higher and higher, which are mainly manifested in the following aspects: mechanical performance, that is, solid, resistant to falling, and able to handle long-distance transportation. For example, good moisture-proof and airtightness can ensure that the product will not be affected with damp during storage and transportation, and that the product will not leak and cause cement loss. In terms of automation function, the filling can be carried out efficiently, quickly and accurately. At present, the full plastic square bottom valve pocket has been widely used in cement enterprises at home and abroad. It is characterized by fast filling, clean and beautiful, good sealing, fine printing, large packaging volume, and can be packed standing, which is very suitable for stacking and transportation operations. With the automatic filling of packaging machinery, the valve opening on the top can achieve the effect of automatic sealing after being filled with cement, saving time and effort.

2、 Advantages of plastic woven square bottom valve pocket

Plastic woven square bottom valve bag is produced by a special square bottom valve bag making machine. It is a low-cost square bottom valve pocket suitable for automatic packaging, which is produced by heat sealing, using PP woven bag cylinder with film covering, and processed by heat sealing production process. The upper and lower sealing of this square bottom valve pocket does not require any sewing thread. Instead, the film covering layer of woven fabric is used for stable heat sealing. The film covering at the bottom of the bag, as well as the film covering of the valve opening sheet and the back cover sheet, are softened by hot air and then sealed together by pressurization. The square bottom valve pocket production line has changed the four separate production and processing processes of cutting, printing, valve opening and sewing, improving production efficiency and product quality, and saving a lot of manpower and materials. No sewing is needed in the production process, which not only reduces the production process, but also saves sewing thread and kraft paper sewing edge. It is essential to avoid the seam ends and paper edges from entering the cement concrete, ensure the construction quality and keep the site environment clean. It is conducive to the recycling of used packaging bags and the requirements of protecting the ecological environment. The latest drilling method and microporous drilling technology are adopted. The hole diameter is very small, and the hole density is large. The hole diameter and density can be adjusted according to the can exhaust, so as to reduce the problem of excessive loss of bag strength caused by drilling. In the process of filling and transportation, the phenomenon of ash spraying and leakage is greatly reduced, the filling site and loading and transportation environment are improved, and the loss and waste of cement are reduced, meeting the requirements of energy conservation and environmental protection development. The square bottom valve bag packs cement, making the filled bag square, improving the stacking shape, improving the product packaging level, good appearance and quality, and expanding the market influence of cement products in China. The most important thing is that the cement enterprises realize automatic mechanical operation in the process of cement filling, stacking, storage, loading and transportation, which can reduce a lot of human resources and save expenditure costs.
