Engineered to deliver exceptional seal reliability, precision dosing, and high overall equipment effectiveness (OEE).
Established in 2015, Henan Collins Machine Co., Ltd. has dedicated its operations to the design, research, and manufacturing of advanced automated packaging solutions. With over 20 national invention patents, Collins is a recognized pioneer in developing integrated industrial lines, including labeling, filling, capping, coding, sealing, and shrink-wrapping systems.
Operating from our modern 5,000 m² facility, our team of over 80 skilled engineers and senior technicians utilizes precise production technology to serve contract packagers and OEMs globally. As an ISO 9001, SGS, and RoHS certified enterprise, we strictly adhere to rigorous quality-control benchmarks, ensuring every piece of machinery functions reliably under demanding multi-shift industrial environments.
A comprehensive analysis of multi-lane architecture, sanitary dosing systems, and film sealing thermodynamics.
Sachet packaging equipment is critical to industries requiring unit-dose efficiency, such as pharmaceuticals, cosmetics, foods, and specialty chemicals. A robust sachet machine utilizes either Vertical Form Fill Seal (VFFS) or Horizontal Form Fill Seal (HFFS) kinematics. For high-speed lines, multi-lane VFFS systems are preferred, supporting from 2 to 16 lanes on a single mainframe. This design achieves outputs exceeding 800 sachets per minute while maintaining a compact footprint.
Our OEM engineering focuses heavily on structural rigidity, using SUS 304 and SUS 316L stainless steel frames to minimize resonance at high cycles. Servo-driven draw-down systems control film tension dynamically, adjusting for slight variations in substrate thickness and elastic modulus. This ensure consistent bag lengths and precise eye-mark registration.
Different product behaviors require tailored dosing systems to prevent leakage, underfills, or product degradation:
Sachet seal integrity is critical for product shelf-life. Our custom equipment integrates advanced PID temperature controllers and cartridge heaters, maintaining sealing jaw temperatures within ±1°C. By applying uniform pneumatic or hydraulic pressure across the sealing bar, we prevent channel leaks in laminates like PET/AL/PE, Kraft Paper/PE, or compostable barrier films. For high-speed lines, we offer ultrasonic sealing options that seal through product contamination in the seal area, reducing waste rates to less than 0.05%.

Partnering with a Chinese OEM machine manufacturer like Henan Collins provides distinct advantages in procurement speed, cost efficiency, and technological adaptability. Located within China's primary industrial manufacturing hub, we benefit from a comprehensive domestic supply chain for high-performance steel, advanced motion-control systems, and electronic components.
This ecosystem allows us to achieve shorter production lead times than Western competitors. Key advantages include:
Aligning packaging technology with regional safety certifications and international quality standard protocols.
Our sachet filling equipment is designed to meet strict regulatory requirements. We provide full ISO 9001 certification, SGS factory verification, CE conformity certificates for European markets, and RoHS compliance for electrical assembly lines. For pharmaceutical applications, we design systems according to GMP standards and facilitate 21 CFR Part 11 software environments.
Through our multilingual services, Collins ensures smooth communication for international clients. We offer complete technical documentation in English, Spanish, French, and Russian. Our services cover everything from Factory Acceptance Testing (FAT) to Site Acceptance Testing (SAT), remote diagnostics via VPN, and on-site operator training.
We partner with local engineering groups in key markets across North America, Europe, and Asia-Pacific to provide swift preventative maintenance. Our standard PLC programs and modular control systems allow for quick diagnostics and fast component replacements, minimizing downtime on critical production lines.
Procuring automated packaging systems involves evaluating factors beyond initial capital costs. Global procurement managers assess systems based on Total Cost of Ownership (TCO), Operational Equipment Effectiveness (OEE), and long-term integration flexibility.
Pioneering green materials compatibility, smart diagnostic sensors, and automated servo adjustments.
Consumer pressure is driving a shift from complex multi-layer plastics to mono-material laminates and biodegradable films. Our sealing jaw profiles are designed to provide the precise heat control required to seal paper-based and compostable films without burning or compromising seal integrity.
Modern production facilities require real-time data access. Our control panels feature Ethernet and OPC-UA connectivity, allowing operators to monitor temperature, speed, and yield metrics remotely while anticipating maintenance needs before downtime occurs.
By connecting downstream checkweighers with the filling PLC, our machines make automatic micro-adjustments to the dosing system, keeping fills within narrow tolerance ranges and reducing costly product giveaway.
Our sachet filling systems are designed to adapt to a wide range of product categories, maintaining high efficiency across diverse industrial sectors:
Single-serve packaging for ketchup, honey, energy gels, instant coffee powders, and granular spices. These systems feature food-grade SUS 316L contact surfaces, positive cut-off nozzles to prevent dripping, and optional gas flushing to extend shelf life.
Sachet packaging for liquid soaps, face creams, shampoos, and cosmetic samples. Specialized seal profiles ensure clean tears and prevent leakage during shipping.
High-accuracy packaging for powder supplements, dynamic health formulas, and liquid medicines. We offer dust extraction ports, vacuum feeding systems, and complete validation documents to meet strict sanitary standards.
Support equipment including coding systems, continuous vacuum packaging lines, and bottle unscramblers.
