| 1. Match capacity to your production plan | Output rate and operating schedule | Ask for the machine’s rated output and the conditions used to calculate it, including pouch dimensions, material, and configuration. | Actual output can vary with pouch size, material, changeovers, and stoppages. Compare expected good pouches per hour—not just the headline maximum—with your required production volume. | Request a production trial using a representative pouch and material. Confirm how reject rates and planned downtime affect the stated output. |
| 2. Confirm the pouch size and format range | Dimensions and pouch design | Check the supported pouch width, length, bottom gusset, and applicable formats, such as stand-up pouches with or without zippers. | Ensure both current and planned pouch sizes fall within the machine’s specified working range. A pouch’s dimensions and gusset design affect forming and sealing requirements. | Provide drawings or samples of your smallest and largest planned pouch and request a documented compatibility check. |
| 3. Test every intended packaging material | Film and laminate compatibility | Identify the material structure, thickness, sealant layer, and any special properties such as a barrier layer or recyclable design. | Different films and laminates can require different sealing conditions and handling. Do not assume that compatibility with one material means compatibility with another. | Run sample material through a machine trial. Review seal quality, pouch appearance, feeding stability, and any material-specific operating limits. |
| 4. Evaluate sealing performance | Seal type, consistency, and settings | Ask which seals the machine forms and how operators adjust or monitor sealing conditions, such as temperature, pressure, and dwell time. | Suitable settings depend on the material and pouch design. Consistent seals are important for package integrity and should be assessed under repeatable conditions. | Agree on seal-quality criteria before testing. Inspect trial pouches and use appropriate seal-strength or leak-testing methods for your product and application. |
| 5. Check customization and add-on options | Features and pouch accessories | Confirm whether the machine can accommodate options such as zipper insertion, spouts, tear notches, hang holes, or other required features. | Each feature may affect tooling, machine configuration, changeover time, and output. Specify which options are required now and which may be needed later. | Ask the supplier to demonstrate each required feature on a sample pouch and list any additional tooling or configuration needed. |
| 6. Compare changeover and automation needs | Format changes, controls, and staffing | Review changeover procedures, recipe storage, adjustment points, operator interfaces, and which tasks are manual or automated. | Frequent changes between pouch sizes or designs make repeatable settings and clear procedures especially valuable. Include setup and cleaning time in production planning. | Observe a changeover between two representative formats. Ask for training materials and identify the skills required for routine operation. |
| 7. Verify support, maintenance, and integration | Serviceability and line compatibility | Check maintenance access, spare-parts availability, training, service arrangements, utilities, and compatibility with upstream or downstream equipment. | Confirm the machine fits the available floor space and connects appropriately with your filling, inspection, and packing processes. Consider ongoing maintenance as well as purchase cost. | Request a layout and utility checklist, maintenance schedule, recommended spare-parts list, and written details of training and service coverage. |
