| 1 | Product and process fit | 15% | Supported bag types, construction, handle options, and production steps included in the quoted line. | Confirm the proposed equipment can make the required bag designs, including the intended bottom style and handle type. Request sample bags made to the same specification. |
| 2 | Verified production speed | 14% | Rated speed and demonstrated output, recorded in bags per minute for a defined bag size, paper, and handle configuration. | Compare sustained output under the same test conditions, not only the machine’s maximum or no-load speed. Record stoppages and reject bags during the test. |
| 3 | Bag and paper specification range | 12% | Minimum and maximum bag width, height, gusset, paper grammage (g/m²), and roll or sheet requirements, as applicable. | Check that the required product sizes and paper grades fall within the manufacturer’s documented machine limits. Verify these limits against the technical specification and a production trial. |
| 4 | Finished-bag quality and consistency | 12% | Bag dimensions, fold alignment, glue-bond integrity, handle attachment, appearance, and accepted/rejected quantities from a sample run. | Set acceptance criteria before testing. Inspect samples from the beginning, middle, and end of the run, and record defects using the same checklist for every supplier. |
| 5 | Automation and changeover | 10% | Control system, recipe storage, adjustment points, operator tasks, and changeover time between specified bag sizes or formats. | Ask the supplier to demonstrate a changeover and document which settings are automatic or manual. Compare changeover time using the same starting and finishing conditions. |
| 6 | Line integration and utilities | 10% | Equipment included, line layout, electrical supply, compressed-air demand, installation footprint, and upstream/downstream interfaces. | Request a layout drawing and utility list. Check compatibility with the facility’s available power, air supply, floor space, material flow, and planned packaging equipment. |
| 7 | Safety and documentation | 8% | Risk and guarding information, emergency-stop provisions, electrical documentation, operating and maintenance manuals, and applicable conformity documents. | Review documents for the exact quoted configuration and intended destination market. Confirm that manuals, labels, and safety features are supplied with the machine. |
| 8 | Quality control and traceability | 7% | Inspection procedures, component lists, serial-number records, test reports, and documented factory acceptance criteria. | Request the factory test checklist and confirm how the delivered machine will be checked against the agreed specification before shipment. |
| 9 | After-sales service and spare parts | 6% | Warranty terms, service response process, remote-support options, training scope, spare-parts list, and parts availability arrangements. | Compare written commitments, exclusions, response channels, and the recommended initial spare-parts package. Confirm who is responsible for installation and commissioning. |
| 10 | Total cost and delivery terms | 6% | Itemized equipment price, tooling, installation, training, packing, shipping terms, stated lead time, and payment milestones. | Compare like-for-like quotations and identify excluded costs. Confirm delivery milestones and acceptance conditions in the purchase contract. |
