PACKAGING / TRIALS AND ACCEPTANCE
Before ordering a packaging machine, agree what a successful trial must show
The quotation says 400 packets per minute. Your production plan needs usable sauce packets at a dependable rate. Those statements become comparable only when the product, film, observation period and acceptance checks describe the same job.
For overseas buyers preparing a sauce sachet machine purchase from Japan. Use this guide after selecting candidate equipment, before treating a demonstration or trial as purchase acceptance.
Turn the quotation into a testable question
“Can it run our sauce?” is a reasonable opening question. Before an order, it needs a more precise answer: which product and film, which packet and fill quantity, which machine configuration, and which observed result would satisfy the requirement?
SANKO describes packaging tests with customers’ actual fillings and films. TOYO lists product characteristics, packaging material, production efficiency and installation space among the inputs it assesses when proposing equipment.[1][2] These are useful starting points for a shared brief. Neither public statement confirms the test, acceptance criteria or destination support for your proposed purchase.
Give the brief a revision and name the open decisions. If the sauce changes from smooth to one containing pieces, or the film construction changes, ask the maker which conclusions still apply. A result tied to a different sample is evidence about that sample, not an automatic extension to yours.
Keep three purposes distinct. A feasibility trial explores whether a product-and-pack combination is workable. A factory acceptance test (FAT) checks the agreed supplied configuration at the maker before shipment. A site acceptance test (SAT) checks the installed arrangement against the site scope. Which tests form part of your purchase, and who accepts them, must be agreed for that project.
The same requirement can need evidence in two places
A maker may reproduce your product and film at its factory. It may not reproduce the destination’s utilities, room conditions, upstream supply or downstream handling. In its own packaging-machine process, CDA distinguishes pre-shipment FAT at its facilities from SAT after installation at the customer’s site.[3] Use that distinction to ask what can be demonstrated now and what remains for the installed line.
Solid shapes identify the test setup. Dashed lines link observations to records; they do not indicate product flow or automatic approval. Agree the FAT/SAT scope and any repeat checks for the actual project.
Put factory limitations in the record. If a substitute product is used, identify what it can demonstrate and what still needs the actual sauce. If a downstream conveyor is absent, do not mark its effect on the finished pack as tested. Carry those points into the site plan with an owner and a proposed check.
Remote attendance changes how evidence is witnessed, not the need to define it. IMA, for example, describes a remote FAT service with technicians at its plant and customer staff participating through a live connection.[4] If a candidate offers a remote session, agree the views, measurements, access to raw records and opportunity to request a repeat. A short video of moving packets is not the complete acceptance record.
Count accepted packs, and keep the denominator visible
A machine cycle counter, a bag count and a count of packs meeting the agreed checks can describe different outputs. Define the counting point, reject categories and treatment of reworked packs before the trial. For fill measurements, retain individual readings and sample identities rather than relying only on a displayed average.
Fictional example — arithmetic only
Suppose an agreed rule classifies 5,700 of 6,000 packets as acceptable during a 20-minute observation window that includes the recorded stops.
- Accepted-pack proportion
- 5,700 ÷ 6,000 = 95%
- Accepted-pack output over the window
- 5,700 ÷ 20 = 285 packets/min
This is not a recommended test duration, yield target or acceptance limit. The counting rule and checks are assumptions in this example, not a report of a machine trial.
The 285 packets/min describes that observation window. It is not the advertised maximum and does not establish a full shift’s output. Record the warm-up boundary, stops, restarts, material changes and permitted interventions so another reviewer can understand what the number includes.
“Acceptable” also needs a boundary. Passing the agreed line checks does not establish food safety or shelf life. Keep any separate hygiene, process, storage or distribution validation in its own scope with the relevant specialists.
Use one conditions sheet for every candidate
The sheet below is a starting point for discussion, not a universal FAT protocol. The buyer, maker and relevant specialists should agree limits, methods, sample plans and responsibilities for the actual product and equipment. Empty result fields mean the work has not yet been reported.
| Item | Agree before the trial | Record during or after |
|---|---|---|
| Project and test scope | Brief revision; machine configuration; products/formats included; FAT, SAT or a feasibility trial. | Test location, configuration and the checks actually completed. |
| Product and samples | Product identity/lot; viscosity and measurement temperature if known; particles; filling temperature; available sample quantity. | Actual sample lot and condition; substitutions and their agreed limitations. |
| Film and packet | Film structure/revision/lot; roll specification; packet dimensions; seal layout; number of lanes. | Actual film lot, format, tooling and any change from the brief. |
| Fill and measurement | Target quantity/unit; agreed limits; method, sample plan and instrument. Use density if converting mass and volume. | Individual readings and sample identities, not only a displayed average. |
| Observation window | Start/end rule; warm-up treatment; duration; stops, restarts and permitted interventions. | Elapsed time, stop reasons and intervention log under the agreed counting rule. |
| Output and rejects | Total/accepted/rejected/reworked definitions; counting point; required accepted-pack rate and its time basis. | Counts in non-overlapping categories and the actual elapsed-time denominator. |
| Seal and pack checks | Defect definitions; leak/seal checks; method, conditioning and sample positions; separate storage-test scope. | Defect location, sample IDs, observations and the results of the specified checks. |
| Changeover and cleaning | Formats/products to change between; start/end state; steps included; authorised operating and cleaning procedures. | Time and interventions for the agreed task, with remaining hygiene-validation work identified. |
| Installation conditions | Destination/site; electrical supply, utilities, room conditions and upstream/downstream interfaces to confirm with specialists. | Differences from the factory setup; readiness owner and the site checks still required. |
| Evidence and open points | Witnesses; raw records; applicable instrument records; acceptance owner; exceptions; correction and retest/release rule. | Result per requirement; unresolved points; owner/date; evidence needed for the next decision. |
Save the editable conditions sheet (CSV)
The CSV has additional blank columns for the acceptance criterion, actual result, owner and disposition. Keep the product, film and brief revisions with it; a spreadsheet separated from its test basis is difficult to reuse.
End with a decision, an open point or a repeat check
For each requirement, connect the observation to the agreed criterion and a record someone else can inspect. Useful evidence may include time-stamped counts, individual measurements, sample labels, defect photographs, the tested configuration and the people who witnessed the work. Decide what needs instrument or calibration records for the chosen method.
If a criterion is missed, record the finding and the proposed correction or exception. Name who can accept it and which check must be repeated. Avoid a single “passed” label that hides a substituted film, an untested site interface or an unresolved result. Shipment release and final acceptance should follow the decisions agreed in the purchase, not be inferred from the existence of a test report.
Prepare the site handover while the factory evidence is still easy to obtain: the tested setup and settings record, agreed utilities and interfaces, open points, applicable operating/maintenance documents, training scope and service contacts for the destination. Ask the maker to confirm which items are included in its offer.
If you are still comparing machine routes, start with the sauce sachet machine selection guide. For a film-related leak, the film-change trial guide explains why a seal specimen and a production bag can give different evidence.
