4. Key Technical Specifications to Evaluate
When comparing different models, focus on the technical parameters that directly impact performance and reliability. Vacuum pump quality, sealing bar dimensions, and control systems are among the most critical components.
4.1 Vacuum Pump Performance
The vacuum pump is the heart of the machine. Consider the pump capacity (measured in m³/h), ultimate vacuum level (mbar), and pump type. Common options include dry rotary vane pumps, oil-lubricated pumps, and Busch or Becker brand pumps for industrial reliability. For food packaging standards, oil-free or dry pumps reduce contamination risks and maintenance complexity.
4.2 Sealing System Quality
- Seal bar length and width: Must match your bag sizes; wider seals provide better integrity for heavy products.
- Sealing temperature control: Precise digital temperature adjustment ensures consistent seals across different film types.
- Cooling time adjustment: Proper cooling prevents seal damage and improves output quality.
4.3 Control and Automation Features
Modern vacuum packing machines offer programmable logic controllers (PLC) with touchscreen interfaces. These systems allow operators to store recipe-based settings for different products, adjust vacuum and gas flush times precisely, and monitor machine diagnostics. Automation reduces operator error and ensures packaging consistency across production runs.
5. Build Quality, Materials, and Hygiene Standards
The machine’s construction materials significantly affect its longevity and suitability for your application. For food, pharmaceutical, and medical device packaging, the equipment must comply with stringent hygiene regulations.
- Stainless steel construction: AISI 304 or AISI 316 stainless steel is the industry standard for corrosion resistance and cleanability. Check if the chamber, frame, and external panels are all stainless steel or if some components use painted mild steel.
- IP rating: For wet cleaning environments, look for appropriate ingress protection ratings to safeguard electrical components.
- Validated design: For pharmaceutical packaging, equipment should be designed to support ISO 11607 compliance and validation protocols.
