Xiamen Gachn International Co., Ltd. (GACHN Group) is excited to unveil the FK008-III Plastic Woven Valve Sack Making Machine, the latest innovation in industrial packaging solutions. Designed with a focus on speed, precision, and durability, the FK008-III sets a new benchmark in valve sack production, catering to industries that demand efficiency, reliability, and high-quality output.
The FK008-III is the result of independent research and patented innovation, ensuring that users can operate the machine without any risk of infringement litigation. This next-generation valve sack making machine features a patented triangle bag opening technology, a revolutionary approach that combines speed with stability. Unlike conventional machines that rely on suction cups and other wearing parts, the FK008-III uses vacuum negative pressure bag opening, eliminating excessive wear, maintenance downtime, and operational inefficiencies.
Equipped with full servo control and an intuitive human-machine interface (HMI), the machine offers an intelligent, user-friendly experience. Operators can easily manage production lines, monitor performance, and adjust parameters for optimal output, making complex production processes simpler, more precise, and more controllable than ever before.
The FK008-III achieves production speeds of 90–120 bags per minute, matching or exceeding the output of traditional paper bag machines. Its unique bottom sealing mechanism, paired with an integrated correction system, allows the use of single-sided film material for bottom sealing. This reduces raw material consumption significantly—up to $1 per 500 bags—translating into annual savings of $60,000 for a 30-million-bag production capacity.
By integrating intelligent energy-saving features, such as vector frequency conversion and dynamic pressure adjustment, the FK008-III reduces motor energy consumption by 10–30%, saving tens of thousands of yuan annually in electricity bills. The machine’s power module automatically enters standby mode when idle, and intelligently increases pressure when needed, eliminating energy waste and supporting environmentally friendly operations.

The FK008-III supports a wide range of materials and bag specifications, making it highly versatile for multiple industrial applications. Capable of producing bags ranging from 10 kg to 50 kg with weights of 75 grams ±2 grams, it accommodates polypropylene (PP) and HDPE fabrics, laminated with PE for enhanced durability. The machine supports precise fabric width and weight tolerances, ensuring consistent quality for every bag.
Its HD quality print capability delivers premium visual appeal, perfect for consumer-facing packaging. The addition of an optional extended valve allows ultrasonic sealing for products requiring airtight packaging, ideal for powdery or granular materials.
Designed for demanding industrial environments, the FK008-III operates efficiently in extreme temperatures ranging from -20°C to 60°C and can handle dusty, humid, or voltage-fluctuating conditions. Its anti-interference design ensures stable operation, with a failure rate below 0.5%, allowing continuous production for up to 30 days without downtime. This reliability minimizes operational disruptions, reduces maintenance costs, and ensures consistent productivity for large-scale manufacturing facilities.
One of the FK008-III’s standout features is its AI visual inspection system. Capable of detecting both base fabric and bag-making defects, the system ensures that only high-quality products reach the end-user. The AI system offers surgical-level precision, scanning in milliseconds and coordinating multiple motors to correct bag alignment, heat sealing, and cutting operations with minimal error.
The benefits of this system include:
· Reduced Labor Costs: A single operator can manage 3–4 machines simultaneously, potentially saving up to RMB 360,000 annually.
· High Accuracy: Adaptive defect detection reduces missed removals to as low as 0.05%.
· Customizable and Flexible: The system can be tailored to detect specific defects in base fabric or finished bags, ensuring maximum quality control.
· Human-Friendly Interface: The user interface is simple, intuitive, and adaptive, allowing seamless operation and real-time defect tracking.
The FK008-III combines intelligent automation with sustainability. Servo drive loops with 2 kHz response frequency allow needle-level precision at speeds up to 500 bags per minute, reducing scrap rates by 50%. This precision and efficiency reduce material waste and production costs while maximizing throughput.
Moreover, the machine’s energy-saving technologies, including dynamic power adjustments and motor energy optimization, make it an environmentally responsible choice for companies seeking to lower their carbon footprint while boosting productivity.
