1. Define the use case
State the food-storage application, sales channel, target customer and destination country. The buyer remains responsible for local demand, product claims and market-entry requirements.
2. Submit the consumable basis
Identify or supply the intended bag or roll construction, dimensions and material. Do not assume generic film compatibility from a product photo or category name.
3. Freeze the sample identity
Record model Z-K03, current sample label, controls, rated input, frequency, cord or connector, included items and measured dimensions before testing.
4. Sign the operating test
Agree the operating sequence, sample material, evacuation basis, seal inspection, repeat-cycle check and acceptance record. No unsupported vacuum or preservation claim should enter artwork.
5. Reconfirm the packed version
Freeze logo, label, manual, color box, inner protection, barcode and carton mark. Reconfirm final carton dimensions, gross weight and loading reference after the complete set is approved.
6. Tie inspection to the order
The purchase order, golden sample and inspection checklist should reference the same machine, consumable, electrical identity, accessories, artwork revision and packing version.
