The types of valve bags mainly focus on the valve structure and include:
Customized machines are one of our factory's strengths. We have in-house design and development for structures, automation support, mechanical parts processing and inspection, assembly and debugging, and process improvements.
Yes, our equipment can handle kraft paper weighing more than 65g, and film thickness ranging from 0.008 to 0.01mm.
We offer standard YD-5860 and fully-functional YD-5875 tube forming machines. The YD-5860 is suitable for producing tubes with a width of 300-600mm and meets 85% of paper bag size requirements for cement, building materials, food, and chemicals. The YD-5875 is capable of producing tubes with a width of 300-750mm, suitable for larger bags like cement, large food, and chemical packaging.
First, analyze the target market for the bags. For single-market customers like cement and dry-mix building materials, the YD-5860 and YD-2818 are suitable. If you are producing larger bags for cement, building materials, and large food or chemical packaging, then the YD-5875 and YD-2825 would be a better choice, though at a slightly higher price.
A valve bag making machine uses precision cutting, folding, and sealing mechanisms to create valve bags. These bags feature a small valve opening that allows easy filling while ensuring a tight seal to prevent leaks or contamination.
Valve bag making machines are designed for bags with a valve or spout at one end, typically used for packaging granular, powdered, or bulky products like cement, grains, chemicals, and fertilizers.
Compatible materials include:
Valve bag making machines create hermetically sealed bags, ensuring optimal protection for the packaged contents. The one-way valve mechanism prevents external contaminants from entering the bag while allowing excess air to escape, preserving product freshness and integrity. These machines streamline the packaging process, reducing labor and time, and improve overall production efficiency.
The bottomer machine is used during cement bag manufacturing to reprocess the initial bags produced by the tuber machine. It opens, folds, glues, pastes, and compacts both ends (bottom) of the initial cement bag, forming a complete valve bag.
Yes, we offer printing machines for valve bag production lines, which are beneficial for workshop production layout, equipment transportation and customs clearance, and equipment manufacturing timeline coordination.
Integrating a printing system into a valve bag machine is a cost-effective and time-saving solution. It eliminates the need for separate printing equipment, reducing overhead costs and improving operational efficiency. High-quality printing ensures professional branding, enhancing the market appeal of the bags produced.
An open-mouth bag is a straight tube with no seal at the top, where materials are directly poured or filled by gravity and then sealed with an industrial sewing machine. Valve bags have a sealed design with a valve for easy filling. After filling, the material seals the valve, ensuring no leaks and offering advantages such as accurate weighing, ease of stacking, and labor-saving.
A valve bag features a valve at one end, which is used for easy filling. The bag is sealed by the material pressing on the valve, ensuring no leakage. There are external valve bags and internal valve bags, where the internal valve automatically seals after filling, while external valve bags require manual folding.
Our machines are made from high-strength alloy steel and high-quality stainless steel. Key components, such as servo motors and PLC control systems, come from well-known brands like Siemens and Mitsubishi.
Yes, we support customization. You can provide specific requirements such as bag type, printing needs, and automation level, and we will design accordingly.
Yes, we can arrange for engineers to assist with installation and commissioning at your facility, or we can provide remote video guidance.
We offer 24/7 online technical support, remote troubleshooting, spare parts supply, and regular maintenance services.
