2. Equipment Technical Barriers: Collaborative Value of Automatic Production Lines

• Configuration Logic of Dual Automatic Production Lines
  Full-process linkage (printing → laminating → slitting → bag-making) + equipment layout optimization plan for 9,000㎡ workshop
• Core Technical Advantages
  Practical application of key technologies in specific scenarios (e.g., 50% improvement in sealing performance of nozzle bags via automatic welding)
• Equipment Iteration History
  From factory establishment (2003) to over 10 sets of new equipment in use, following update logic adapted to flexible packaging industry upgrading

3. Equipment Applicable Scenarios and Practical Application Cases

• Industry Adaptation
  Packaging production solutions for food, chemicals, daily necessities (e.g., high-speed bag-making machines applied in blueberry/cherry tomato packaging)
• Typical Cases
  Equipment-linked production process for customized aluminum foil bags (a food enterprise) — full-process coordination (printing → laminating → bag-making → inspection)
• Selection Reference
  Equipment combination suggestions for different packaging needs (e.g., prioritize nozzle welding machines + high-speed bag-making machines for mass production of nozzle bags)
