Packaging Machine Types and Their Pros and Cons Analysis

I. Classification by Packaging Form

‌1. Small Pouch Packaging Machine‌

• ‌Advantages‌:
  • Integrates mixing, measuring, bag-making, printing, and filling functions, supporting continuous operation
  • High filling efficiency (dozens of pouches per minute), suitable for liquid/semi-liquid foods (e.g., ketchup)]
  • Secure sealing with automatic date printing, compliant with food safety standards
• ‌Disadvantages‌:
  • Sensitive to material viscosity; high-viscosity sauces may require parameter adjustments

‌2. Three-Side/Four-Side Sealing Packaging Machine‌

• ‌Advantages‌:
  • Adaptable to various sauces (e.g., chili oil, hot pot base), easy to operate
  • Diverse sealing styles (back-sealed bags, stand-up pouches, etc.), customizable
• ‌Disadvantages‌:
  • Bag-making precision relies on servo motor control, resulting in higher maintenance costs

‌3. Bagged Automatic Packaging Machine‌

• ‌Advantages‌:
  • Uses piston volumetric measurement with precision error <1mm
  • Complies with GMP standards; 316L stainless steel material for easy cleaning
• ‌Disadvantages‌:
  • Complex initial setup requiring professional operation

II. Classification by Automation Level

‌1. Fully Automatic Packaging Machine‌

• ‌Advantages‌:
  • Fully unmanned operation, increasing production efficiency by 3-5 times
  • Intelligent temperature control (PID adjustment) ensures stable sealing quality
• ‌Disadvantages‌:
  • High equipment investment, potentially burdensome for SMEs

‌2. Semi-Automatic Packaging Machine‌

• ‌Advantages‌:
  • Suitable for small-batch production with high flexibility
  • Lower cost, ideal for small workshops
• ‌Disadvantages‌:
  • Relies on manual assistance, resulting in lower efficiency

III. Industry Application Recommendations

• ‌Large Enterprises‌: Prioritize fully automatic four-side sealing machines for efficiency and multi-product adaptability
• ‌SMEs‌: Recommend bagged automatic packaging machines to balance cost and precision
• ‌Startups‌: Consider semi-automatic equipment to reduce initial investment
