| Rated production speed | Rated containers per minute for the proposed machine and the specific product, label, and application configuration. Output depends on container shape, label size, spacing, and line conditions. | A written speed specification and a demonstration using representative containers and labels. | Compare machines using the same test materials and count correctly labeled containers over a timed run. |
| Label placement and repeatability | Position, skew, wrinkle, and seam consistency against tolerances agreed for the application. There is no single accuracy figure that applies to every label and package. | Acceptance criteria, sample output, and the measurement method used during testing. | Measure label position and inspect defects across a representative production batch. |
| Product and label compatibility | Supported container shapes and dimensions, label materials and sizes, and whether the machine handles wraparound, front-and-back, or other required applications. | Documented operating range and a successful test with the buyer’s product and label stock. | Check operation at the smallest and largest intended product and label dimensions. |
| Changeover and adjustment | How the machine is adjusted for different product formats, which parts require tools, and whether settings can be saved or reproduced. | Changeover instructions, a list of format parts, and a witnessed changeover demonstration. | Time a changeover between two agreed formats and verify the first acceptable labeled product. |
| Machine construction and environment | Frame and product-contact material specifications, guarding, cleanability, and suitability for the actual production environment. | Material list, drawings, and applicable ingress-protection ratings for specified electrical components, where relevant. | Verify materials and component ratings against the purchase specification; do not infer suitability from appearance alone. |
| Sensors and fault handling | Label-gap and product detection, low-label or end-of-roll alerts where specified, jam response, and clear fault messages. | I/O or functional description, alarm list, and a demonstration of the agreed fault conditions. | Test sensor performance using the supplied label stock and check that faults stop or alert the machine as specified. |
| Controls and integration | Operator controls, available language options, recipe handling, and required interfaces with upstream or downstream equipment. | Control-system description, interface details, and a written list of included integration signals or protocols. | Confirm compatibility with the existing line and demonstrate start, stop, speed adjustment, and relevant line signals. |
| Safety and regulatory documentation | Guards, emergency stops, electrical documentation, and the requirements applicable in the machine’s destination market. A CE marking relates to applicable EU requirements; it is not, by itself, a general quality rating. | Risk and compliance documents applicable to the order, operating instructions, and electrical schematics. | Have the documents and machine configuration reviewed against the destination-market requirements before shipment. |
| Quality management and traceability | Documented inspection and testing processes, component traceability, and the scope and validity of any claimed quality-management certification. | Relevant inspection records and certification details, including the certified entity and scope where applicable. | Check that documentation covers the facility and activities relevant to the machine being purchased. |
| Factory acceptance test | Agreed test conditions, sustained output, labeling quality, alarms, safety functions, and included accessories. | A signed test plan and recorded results using representative production materials. | Make shipment approval contingent on passing the acceptance criteria written into the order. |
| Installation, training, and after-sales support | Installation options, operator and maintenance training, spare-parts availability, response arrangements, and warranty terms. | Written warranty, service contact process, spare-parts list, and manuals in the agreed language. | Confirm responsibilities, costs, response arrangements, and exclusions in the quotation and contract. |
