Packaging Machine Sample Test Protocol

A sample video shows that a machine moved product under one observed setup. It does not by itself prove sustained output, accuracy, seal quality, cleanability or compatibility with every future material. A useful sample test begins with controlled inputs and written acceptance criteria. This protocol helps buyers prepare evidence before a machine recommendation or factory acceptance test.

1. State the decision the test must support

Decide whether the trial is screening a dosing principle, confirming package handling, comparing two configurations, preparing a quotation or accepting the ordered machine. A small early-stage screening test should not be presented as final acceptance evidence. Record the test stage, responsible reviewers and questions that remain open.

List the exact product, package, target dose, tolerance, output condition and quality checks. Where a destination rule or internal standard applies, the buyer should supply the relevant criteria or involve a qualified reviewer. The machine supplier should not invent a regulatory acceptance method.

2. Control the product sample

Record product name or internal code, lot, manufacturing date, storage condition and the properties that affect feeding or filling. For powders and granules, useful inputs can include bulk-density range, flow behavior, particle dimensions, dust, fragility and segregation. For liquids and pastes, useful inputs can include viscosity at a named temperature, foam, particles, stringing, corrosiveness and cleaning sensitivity.

Send enough representative material for setup, adjustment, the measured run and retained samples. If a substitute is used, label the result as a substitute-material test and state what the substitution cannot prove.

3. Control the packaging sample

Provide the intended bottle, jar, cap, pouch, film, label or carton from a controlled lot. Record dimensions, material information, closure, seal area, artwork orientation and any supplier tolerance available. Samples should include expected variation rather than only ideal pieces selected by hand.

For rollstock, record roll width, core, diameter, winding direction, print repeat and registration mark. For premade pouches, record flat dimensions, gusset, zipper or spout, opening behavior and seal zone. Package identity must remain linked to the test record.

4. Agree setup and measurement methods

List the installed filler, feeder, pump, nozzle, forming set, guides, sealing parts, printer and inspection options. Record software or recipe version and key settings without publishing credentials. Define the measuring instrument, resolution, calibration status, sample frequency and calculation method.

For dose or weight checks, agree whether results are net or gross and how tare variation is handled. For seals, agree the inspection or test method. For caps, labels or codes, define the visible defect criteria. Avoid selecting only good packs for the record; identify rejects and stoppages during the observation window.

5. Separate setup, steady running and disturbance tests

Record setup packs separately from measured output. Once the process is stable, run the agreed sample size or duration and log accepted packs, rejects, stops and adjustments. If refill, splice, pouch replenishment, container variation or downstream stop behavior matters, include a named disturbance test rather than assuming steady running represents the production day.

Report accepted output under the test conditions. Do not multiply a short cycle observation into a guaranteed shift output without accounting for refills, cleaning, inspections, changeovers and planned or unplanned stops.

6. Review cleaning and product recovery

After the run, inspect remaining product, dust or drip points, disassembly needs and surfaces that require cleaning. Record recovered and discarded material only when measured with an agreed method. A test on one product cannot establish the cleaning method for a different allergen, color, active ingredient or corrosive material.

For food-related review, FDA Food Code cleanability and food-contact principles can help frame questions, but the document is not a packaging-machine certification. Applicable process and destination requirements remain part of the buyer’s technical review.

7. Produce an evidence package and open-item list

The report should include participants, date, machine configuration, product and packaging identity, settings, raw measurements, accepted and rejected results, photos or video references, deviations and unresolved questions. Keep claims inside the observed conditions. If the result changes the proposed configuration, update the quotation and acceptance plan.

Use the machine FAT acceptance checklist for the later acceptance stage and the powder material data checklist or liquid filling selection checklist to prepare inputs.

Information to send before a sample test

• Product identity, lot, properties, hazards and representative quantity.
• Packaging identity, drawings, material data and representative variation.
• Target dose, tolerance, accepted output and defect criteria.
• Required configuration, utilities, printer or inspection options.
• Measurement method, sample size and destination requirements.
• Questions the trial must answer and conditions it cannot prove.

Send the sample-test inputs to MUJIU so the trial scope can be confirmed before material is shipped.
