Vacuum packaging machines extend product shelf life by removing air from packaging, preventing oxidation and bacterial growth. 1. Chamber Type
Single chamber machines are suitable for small to medium production. Double chamber machines offer higher throughput with alternating operation. External vacuum sealers use a nozzle for large or irregular shaped products that don't fit in a chamber. 2. Seal Bar Length
Choose a seal bar length that accommodates your largest bag width. Common lengths range from 300mm for small operations to 1100mm for industrial applications. 3. Vacuum Pump Capacity
Higher capacity pumps (measured in m³/h) provide faster cycle times. Consider 20m³/h for medium production and 40m³/h or higher for high-volume operations requiring quick cycle times. 4. Applications
Food products: meat, cheese, vegetables, prepared meals, and dry goods. Industrial products: electronic components, hardware, chemicals, and pharmaceutical items requiring moisture protection. 5. Additional Features
Gas flushing (MAP) for modified atmosphere packaging extends shelf life further. Date coding integration for production traceability. Stainless steel construction for food-grade and pharmaceutical requirements. Weumi vacuum sealers are suitable for food processing, pharmaceutical, and industrial applications.
