80g Valve Bag adstar Bag Making Machine

With the acceleration of industrial automation and increasingly stringent packaging quality requirements, plastic woven bags for industrial packaging are facing unprecedented challenges. These challenges are mainly reflected in mechanical performance, usability, automation functions, cost control and other aspects. In response to these requirements, Gachn group timely launched a new generation of  W&H CONVERTEX automatic valve sack converting machine - which quickly won wide acclaim in the market with its excellent functions and features.

Superiority of mechanical properties

The square bottom valve mouth woven bags produced by the Gachn group W&H CONVERTEX automatic valve bag converting machine  perform particularly well in terms of mechanical properties. The bottom of the bag and the valve opening are sealed extremely firmly. Hot air welding technology is used to avoid the weak link of sewing needle holes in the bottom bag, so that the entire bag body is evenly stressed in the event of a drop, and the anti-fall strength is significantly improved. In addition, the inner layer of the bag is made of PE material, which is suitable for filling temperatures below 110°C, further enhancing the stability of the physical properties of the valve bag.

2. Superiority of use performance

Good sealing: The manufacturing process of the valve bag requires the use of laminated bag tubes to ensure the sealing of the bag body. During the processing, the bag body was not damaged due to scratches or burns by the bag making machine, further ensuring its sealing performance. In contrast, after the seam-bottom bag is filled, the packaging materials, especially powdery materials, can easily leak out from the seams, while the valve bag completely avoids this problem.

The valve port is tightly closed: The characteristic of the valve bag is that the valve port automatically closes after the material is filled. The valve bag can automatically close tightly when filled. If the customer needs, the valve port can also be completely sealed by heat sealing pliers or using ultrasonic waves on the filling line to completely eliminate leakage. However, the seam-bottom valve bag cannot be filled fully, the material easily flows out from the valve opening, and it cannot be completely sealed.

3. Advantages of automation functions

Gachn group from PP woven to printing and converting automatic also excel in automation functions. The built-in automatic control tension transmission system not only does not damage the bag body, but also ensures the accurate position and synchronized operation of the bag during production and transportation. Through the punching device, the bag seal and the valve mouth piece are bonded to each other, making the valve mouth piece stronger and ensuring the stability of high-speed filling. In addition, the built-in opening tool can also pre-check the bag body to ensure the high quality and high yield of the valve bag.

4. Advantages of cost control

On the premise of meeting the above mechanical performance, usability and automation functional requirements, the Gachn group bag making machine also achieves a significant reduction in production costs through an innovative adhesive-free heat sealing production process. This production method does not require the use of special adhesives for hand-made bags, and saves plastic raw materials and manual labor to a great extent. At the same time, due to the excellent sealing and anti-fall performance of the valve bag, material waste and environmental pollution caused by breakage and leakage are reduced, further reducing the customer's overall cost.

To sum up, the Gachn group bag making machine and its valve bag product have excellent performance in many aspects such as mechanical performance, usability, automation functions and cost control, and fully meet the high requirements of modern industrial packaging for plastic woven bags. With the further development of industrial automation, valve bags will be widely used in more fields, bringing significant improvements to customers' production efficiency and economic benefits.
