How do you compare air fryer liner base sizes?
A useful liner inquiry begins with measurements that describe the same part of the product. Zhongji's air fryer liner range lists 19 sizes, and every listed size is a base measurement followed by height. The opening is wider than the base. This distinction matters when an inquiry starts with a photograph, an equipment model name or a single number taken from a basket. A clear measurement record makes the next conversation about a particular liner, instead of leaving the measurement convention unresolved.
Which part of a round liner does the first number describe?
For a round liner, the first number describes base diameter and the second describes height. A 16 × 4.5 cm round liner therefore has a listed base diameter of 16 cm and a listed height of 4.5 cm. This label does not give the opened top diameter. Record the basket's internal base measurement separately from its opening measurement, and name both in your drawing. When two people exchange photographs, write the units beside the numbers so that a value is not later mistaken for millimetres or inches.
How should square and rectangular dimensions be written?
The sequence for square and rectangular liners is base length × base width × height. Preserve the complete sequence when you copy a size into an inquiry. The listed 20.5 × 13.5 × 4.5 cm rectangular format and the 20.5 × 15.5 × 5 cm format share a first dimension, but differ in width and height. Writing only “20.5 cm liner” would leave that selection ambiguous. Use a drawing to show which side you call length, and keep that orientation consistent in later sample photographs and approval notes.
What are the 19 listed base sizes?
Use this table as a shortlist of published formats. It records liner measurements, rather than a list of appliance brands or model approvals. The shape name is part of the specification, including whether tabs are present.
| Shape | Base dimensions in cm | Measurement order |
|---|---|---|
| Round | 16 × 4.5 | Base diameter × height |
| Round | 20 × 4.5 | Base diameter × height |
| Round | 23 × 4.5 | Base diameter × height |
| Square | 14 × 14 × 4.5 | Base length × width × height |
| Square | 16 × 16 × 4.5 | Base length × width × height |
| Square | 20 × 20 × 4.5 | Base length × width × height |
| Square | 23 × 23 × 4.5 | Base length × width × height |
| Square | 12 × 12 × 5 | Base length × width × height |
| Square | 16 × 16 × 7 | Base length × width × height |
| Rectangular | 20.5 × 13.5 × 4.5 | Base length × width × height |
| Rectangular | 22 × 14 × 4.5 | Base length × width × height |
| Rectangular | 20.5 × 15.5 × 5 | Base length × width × height |
| Rectangular | 22 × 17 × 5 | Base length × width × height |
| Rectangular | 28 × 15 × 5 | Base length × width × height |
| Rectangular | 31 × 20.5 × 5 | Base length × width × height |
| Square with tabs | 16 × 16 × 4.5 | Base length × width × height |
| Square with tabs | 20 × 20 × 4.5 | Base length × width × height |
| Round with tabs | 16 × 4.5 | Base diameter × height |
| Round with tabs | 20 × 4.5 | Base diameter × height |
What should you measure on the intended basket?
Prepare a drawing showing the internal base, the opening and the depth you want considered. For a round basket, label the internal diameter measurement. For a square or rectangular basket, label both internal base dimensions. Photograph the measurement points where possible, because a bare number cannot show whether it was taken at the base or at the rim. Keep any handles, corner shapes or other features visible in the reference material. Ask which details need a further measurement rather than filling an uncertain value with a guess.
How do you record an opening dimension that is not published?
Treat the opening as a separate confirmation item. The catalogue states that it is wider than the base, but does not supply a finished opening dimension for each format. Ask for that measurement on the selected sample or drawing. Do the same for tolerances: the size table supplies published dimensions, while an agreed tolerance belongs in the specification you review. Keep a short list of unresolved dimensions with the sample request, so receiving a sample does not accidentally turn an unanswered measurement into an approved value.
Why should height remain visible throughout the selection?
Several formats can share a base while their listed heights differ. The plain square range, for example, includes 16 × 16 × 4.5 cm and 16 × 16 × 7 cm liners. Keep the full size on the sample label and approval sheet. Review the opened sample against the intended basket and the height requirement you recorded. If your requirement changes after that review, update the drawing and product description together. A sample identified only by its base can leave the next order referring to a different complete format.
What changes when the selected format has tabs?
The round and square tabbed formats have their own entries in the table. A matching base dimension does not replace a review of the complete outline. Ask for the tab shape and position to be included in the sample or drawing information, and keep the tabbed format's name on your inquiry. Compare the opened sample with the intended basket before you approve it. Avoid using a plain-format photograph as the sole approval reference for a tabbed order, because it does not document the feature you have selected.
How can you turn measurements into an approval record?
Use one record for the candidate you are reviewing. Include the shape, complete listed dimensions, paper weight, colour and sample identifier. Add your basket drawing and photographs, and note which opening measurements or tolerances are still awaiting confirmation. When you review a sample, record the conclusion and any requested changes against that same candidate. This creates a useful distinction between a format being considered and the final specification being approved. It also lets your packaging review refer to the same liner instead of an earlier shortlist entry.
How do you check that a measurement record is understandable?
Before sending a measurement record, read it without relying on the equipment photograph. Can another reader identify the base measurement, the opening measurement and the height requirement from the labels alone? Add arrows showing the measurement points, and keep any ruler scale visible in the supporting images. Separate the catalogue size being considered from measurements you have taken yourself. If two measurements appear inconsistent, retain both with their original labels and ask for clarification; do not average them into a new size. Date the record and identify the equipment examined. This gives the sample discussion a clear reference when a drawing or photograph is revised later.
What information belongs in the first inquiry?
Send the selected catalogue format together with your equipment details, internal basket measurements and required height. Include the paper grade, natural brown or white colour, retail pack count, total packs and destination. Explain whether a stock size is being considered or a custom drawing is required. Stock sizes have no minimum order; custom sizes and printed packaging start from 1,000 packs. Ask for the relevant sample and quotation before final approval. Contact sales@zhongjipaper.com, and attach the drawing that identifies your measurement points.
