A well-designed bag packaging line is the key to achieving these goals.
Hualian, a leading enterprise in the field of packaging equipment, focusing on providing customized packaging systems for the engineering plastics industry. These production lines integrate automatic bagging machines, measuring and filling systems, The Bag Closing System, Conveyor, and Robotic Palletizer are core components that precisely solve the unique pain points of plastic particle packaging. This guide will provide you with a comprehensive understanding of the selection, deployment, and optimization of engineering plastic packaging solutions to help your business develop steadily.
Understanding Engineering Plastics Packaging
The core difference between engineering plastic packaging and ordinary packaging lies in the physical properties of the material itself – plastic particles are small in size, have strong fluidity, are prone to static electricity, and need to be protected from moisture and pollution at the same time. The core objectives of engineering plastic packaging include: maintaining the purity of materials, ensuring precise measurement (key to B2B transactions), improving loading and unloading efficiency, and complying with industry standards.
The mainstream packaging forms of engineering plastics are open bag (with open mouth bagging machine), valve bag and polypropylene woven bag, which are perfectly compatible with the packaging system of Hualian. Whether serving the automotive, electronic or construction industries, 15 kg and 25 kg are the most mainstream specifications for the distribution of plastic particles, and Hualian’s 15 kg packaging line and 25 kg packaging line are designed to meet these needs, achieving a balance between speed and precision.
How a Complete Engineering Plastics Packaging Line Works
A set of efficient engineering plastic bag packaging line is an organic whole composed of multiple components that work together, and each link is designed to eliminate bottlenecks. Hualian’s turnkey system ensures seamless integration of all steps, from particle measurement to palletizing and shipping. The specific process is as follows:
Step 1: Measuring and Filling System
The packaging process begins with precise measurement – this is the core link to ensure customer satisfaction. Hualian’s Measuring And Filling System Adopt volumetric or weighing technology to ensure that each bag of material accurately reaches the designated weight.For plastic particles, the weighing type filling is the first choice because of its higher precision (error ±0.1%), which can effectively avoid the cost waste of over-filling and customer complaints of under-filling.The system is seamlessly connected to the raw material warehouse, and the particles are gently transferred through a spiral or pneumatic conveying method to prevent material damage or static electricity accumulation.
Step 2: เครื่องบรรจุถุงอัตโนมัติ
After the measurement is completed, the plastic particles will enter the automatic bagging machine. Hualian provides two core solutions for the engineering plastic industry: high-speed pre-made bagging machine and open-mouth bagging machine. The automatic bagging equipment grabs and opens the packaging bag (woven PP bag, PE bag or composite bag) through the mechanical arm, and then receives the measured particles. For open bag applications, the equipment will continuously fix the bag mouth during the filling process, completely solving the problem of easy spills and leaks in manual bag filling. Hualian’s system can achieve a speed of up to 120 bags per minute, and the switch between 15 kg and 25 kg specifications is quick and convenient.
Step 3: ระบบปิดกระเป๋า
After filling, the packaging bag will enter the Bag Closing System of Hualian This is the key link to ensure product quality. Hualian offers a variety of solutions, including heat sealing, sewing, and ultrasonic sealing, each optimized for specific bag materials and application scenarios: heat sealing is suitable for PE bags and can provide moisture protection; Sewing is suitable for woven bags in a dry environment; Ultrasonic sealing is suitable for high-speed production lines. Hualian’s bag sealing system has an automatic tension control function, ensuring that the sealing is firm and the bag body is not damaged, while seamlessly coordinating with the bagging machine to maintain a stable production line speed.
Step 4: Conveying System
The sealed packaging bag will be transferred to the next stage through the conveyor belt. Hualian’s conveyor is specially designed for plastic particle packaging bags: it uses low-friction smooth belts to prevent bag body damage, the speed can be flexibly adjusted according to upstream and downstream equipment, and it also supports inclined / lifting design to optimize space utilization. The conveyor is equipped with intelligent sensors that can detect bag or bag body offset in real time, triggering an automatic alarm to reduce downtime. For the 25kg packaging line, Hualian has specially configured heavy-duty conveyors to ensure stable load-bearing.
Step 5: Robotic Palletizer
The last step of the bag packaging line is stacking. The robotic palletizer of Hualian adopts advanced visual system and customized gripper to stack 15 kg or 25 kg packaging bags into stable and neat pallets. Compared with manual stacking, the robot system completely eliminates human error, reduces the labor intensity of workers, and can maintain a unified stacking pattern – which is crucial for transportation safety. The equipment can be connected to the warehouse management system (WMS) to realize batch traceability, and can switch to stacking mode in a few seconds to adapt to different transportation needs.
Advantages of Engineering Plastic Packaging Lines
Investing in an integrated bag packaging line instead of scattered manual operations can bring revolutionary improvements to plastic particle enterprises. Hualian’s customized system further amplifies these advantages:
lncreased Efficiency and Throughput
The limit speed of manual packaging plastic particles is 10-15 bags/minute, while the speed of Hualian’s automatic production line can reach 80-12 bags/minute. The single-shift capacity of the 25kg packaging line is more than 4,000 bags, and the capacity of the 15kg packaging line is even higher – completely eliminating the backlog of orders and accelerating the delivery cycle. Component integration and rapid specification switching design further improve production efficiency.
Reduced Labor and Operational Costs
A manual 15kg packaging line requires 3-4 workers per shift, while Hualian’s fully automatic system requires only one operator to monitor. The return on investment can usually be achieved within 12 to 18 months, just by saving on labor costs. In addition, precise measurement reduces material waste, and energy-saving components such as the automatic bagging machine reduce energy consumption while also reducing rework costs due to bag body damage.
lmproved Accuracy and Consistency
The weight error of manual filling is usually up to ± 5%, which is easy to cause customer complaints and compliance risks. The Measuring And Filling System of Hualian ensures that the error is within ± 0.1%, ensuring that every bag of product meets the standard. Stable bagging quality and palletizing mode can also reduce transportation damage – Hualian customer feedback, after launching its packaging line, the transportation loss rate has decreased by an average of 40%.
Enhanced Safety and Compliance
Dust from plastic particles may be harmful to the respiratory system, and handling heavy bags can lead to work-related injuries. Hualian’s automated production line minimizes direct contact between personnel and materials: the automatic bagging machine and robotic palletizer handle high-risk processes, and closed conveyors reduce dust spread. The system also has batch coding, weight verification, and audit tracking functions, which perfectly meet the requirements of ISO and industry-specific specifications.
Hualian Case Examples
After a well-known domestic engineering plastic enterprise adopted the Hualian 25kg packaging line to replace manual packaging, the production capacity increased by 300%; After a certain European customer activated the 15kg packaging line, the labor cost was reduced by 70%, and the return caused by the weight problem was completely eliminated. Another customer connected the Bag Closing System with the Conveyor to the existing equipment, reducing downtime by 25% and significantly improving the sealing quality.
