Pass/Fail Checks for a Heat Shrink Wrapping Machine FAT
A buyer's guide to defining practical factory acceptance test criteria for an L-seal hood heat shrink wrapping machine, using the stated sealing area and power supply as reference points.
Before signing off, decide which results will count as pass or fail on the factory floor, not just in the supplier's brochure. For an L-seal hood machine, start with the seal itself: agree a sample pack size within the stated 700 × 600 mm maximum sealing and cutting area, then define visible criteria for a complete seal, a clean cut, and no film burning or tunneling. Ask the supplier to run repeated cycles and record how many pass.
Next, tie checks to the stated 220 V AC, 50 Hz supply. Confirm the test machine is configured for that supply and ask what the buyer must provide at site. For shrink quality, define an acceptable wrapped result on the specified packaging film: even shrinkage, no holes, and a pack that holds together. Agree who supplies film for the test and how many samples count.
Build a simple acceptance sheet: seal integrity, cut quality, shrink appearance, cycle repeatability, and safety guards. Set a pass threshold for each before the test.
Before requesting a quote, confirm with the supplier which tests they will run, what sample packs and film they need, how results are recorded, and whether the quoted configuration matches the stated sealing area and power supply.
