Product Description

Satisfied Packing small bag packaging lines are designed specifically for 25-50kg bagged products and are widely used in the small bag packaging needs of new energy lithium battery materials, chemical industry, food industry, pharmaceutical industry, rubber and plastics industry, and other fields. They cover the entire process from material storage, quantitative feeding, automatic bagging, weighing and packaging, to vacuum heat sealing, weight re-inspection, bag reshaping, and rejection of defective products, and then to boxing and sealing, palletizing and wrapping, intelligent transfer, and automated warehousing. All equipment supports modular combination, full-process automated linkage, and MES/DCS system data integration. Core equipment features high precision, dustproof, and high-speed design, and is specially customized for materials with different characteristics such as lithium battery ultrafine powder, food powder, and pharmaceutical raw materials. It can achieve intelligent and unmanned packaging of standard small bag sizes such as 25kg, helping companies improve small bag packaging efficiency, reduce labor costs, and achieve intelligent and unmanned production.

Core Advantages

  1. **Specifications for Small Bag Packaging:** Primarily designed for 25kg standard small bag packaging, the entire process is miniaturized to accommodate the characteristics of small bags, featuring a compact design and small footprint, suitable for small bag packaging workstation layouts.
  2. **High Precision and High Speed:** The core packaging equipment achieves a metering accuracy of 0-20g and a packaging efficiency of ≥40 bags/hour, balancing accuracy and capacity to meet the needs of large-volume small bag packaging.
  3. **Fully Automated Process:** From material storage, bag loading, packaging, sealing, and re-inspection, to boxing, sealing, palletizing, wrapping, transfer, and warehousing, the entire process requires no manual intervention, significantly reducing labor costs.
  4. **Customization for Multiple Materials:** Specially designed for materials with different characteristics, such as lithium battery ultrafine powder, food/pharmaceutical grade powders, and conventional chemical powders, meeting various requirements such as dust prevention, low gas content, and hygiene standards.
  5. **Modular and Easy-to-Combine:** All equipment is modularly designed, allowing for free combination according to customer capacity, workshop layout, and automation needs, balancing versatility and customization.
  6. **Full System Data Integration:** Reserved for MES/DCS/WMS integration. Communication interfaces enable real-time data uploading and remote control of packaging, transshipment, and warehousing processes, supporting end-to-end product traceability.
  7. Multi-industry coverage: Deeply adaptable to the small-bag packaging needs of industries such as new energy lithium battery materials, chemicals, food, pharmaceuticals, and rubber and plastics. One device can adapt to multiple materials, reducing equipment investment costs.
