Runjia Paper · Buyer Guide
A flat-paper grease test can look acceptable while oil escapes through a fold, cut, corner or unsuitable liner geometry during actual use. Ask the air fryer paper liner supplier for a same-spec review path before deposit.

Direct Answer
Ask the air fryer paper liner supplier to separate base-sheet grease permeability from the finished liner's leakage at folds and corners. Confirm paper grade, coating side, die-cut geometry and intended food, time and temperature before testing. Use an agreed controlled food-simulant or application trial with a representative basket and record leakage location and timing. A laboratory paper result does not automatically approve the formed product, and no liner should obstruct the appliance's required airflow or touch a heating element.
Quick takeaway: ask the air fryer paper liner supplier to approve the exact product, test conditions and retained sample together.

Is This Product Right for Your Market?
This air fryer paper liner supplier guide is intended for private-label retailers and foodservice distributors. Match the proposed formed air fryer paper liners to the actual use, equipment, destination and package configuration. Ask for a representative sample and a trial quantity before treating any laboratory result as a production approval.
What does the material test actually measure?
ISO 16532-1 describes grease resistance as a permeability assessment for paper or board and permits creased or uncreased sheets. Specify the tested face, construction and method edition. The result may help compare candidate paper, but a shaped liner adds folds and edges that need separate evaluation. Do not label a surface-repellency result as a through-sheet leakage result. Keep this air fryer paper liner supplier decision connected to an identified sample and acceptance rule.
How should the finished liner be trialled?
Use the intended basket size, liner shape and representative food or defined oil challenge. Weigh or measure the loading consistently, observe the liner at agreed time points, and inspect the basket beneath it after cooling. Record whether penetration occurred through the sheet, at a fold, or around an edge. A trial protocol must also follow the appliance maker's safety instructions. Keep this air fryer paper liner supplier decision connected to an identified sample and acceptance rule.
Which defects matter commercially?
Compare leakage frequency by lot and geometry, not only an attractive new sample. Separate a defective fold from a liner placed in an oversized basket or used with excessive liquid. Keep photos, sample IDs and the approved pack version so a retailer can investigate complaints without assuming every stain is the same defect. Keep this air fryer paper liner supplier decision connected to an identified sample and acceptance rule.
What Should Buyers Compare on the Same Specification?
| Control point | Request | Buyer purpose |
|---|---|---|
| Sheet barrier | Material ID, coating side and relevant permeability method | Screens through-sheet penetration |
| Formed geometry | Corner folds, cuts, wall height and basket fit | Finds leakage paths |
| Trial conditions | Food/oil load, time, temperature and appliance | Matches intended use |
| Acceptance | Leak location, threshold and approved sample | Prevents vague pass/fail claims |
Why Can Quotes Differ?
Compare equivalent GSM, coating, dimensions, wall height, fold design, pack count and testing scope. Additional geometry trials or more stringent rejection thresholds can change converting cost. Calculate accepted liners after the agreed test, not just nominal pieces per carton. Ask the air fryer paper liner supplier to itemize any changed inspection or packaging assumption.
Which Calculation Helps the Buyer Decide?
Illustrative only: 18 leaking pieces among 600 tested liners is a 3% observed failure rate in that sample. It is not a population defect estimate without a defined sampling plan and not a Runjia result. Buyers should agree sample size, allowed defects and retest procedure before ordering. Have the air fryer paper liner supplier identify which inputs are estimates rather than measured results.
When Is This Choice Unsuitable?
- Do not assume a flat-sheet report proves finished-corner performance.
- Pause if the liner geometry obstructs airflow or risks contact with the heating element.
- Do not claim every oil-rich or liquid-heavy food is suitable without an application trial.
What Belongs in the RFQ?
| RFQ field | What to provide |
|---|---|
| Produit | formed air fryer paper liners; format, GSM or gauge, coating, dimensions, core or perforation |
| Commercial | Pack count, carton, artwork, barcode, trial and monthly volume, MOQ, lead time |
| Shipment | Destination port, Incoterm, loading estimate and target date |
| Evidence | Approved sample ID, batch, method, acceptance limit and document scope |
Export Manager Note
Keep the approved sample, written specification and shipment identity together. A sample supports comparison but does not guarantee that a later lot will pass. Ask the air fryer paper liner supplier to flag material, converting or packaging changes before repeat production.

Copyable RFQ Wording
Please ask the air fryer paper liner supplier to quote the attached specification, identify any deviation, and reference the approved sample ID. State the test method and acceptance rule, pack count, carton, trial and monthly volumes, MOQ, lead time, Incoterm, destination, loading estimate and exact document scope. Seek written approval before substitution.
Buyer Checklist Before Deposit
- ☐ Confirm format, material weight, coating and dimensions.
- ☐ Approve core, perforation or formed geometry where relevant.
- ☐ Retain a matching sample and define change control.
- ☐ Agree test conditions, acceptance criteria and technical approver.
- ☐ Confirm pack count, carton, artwork, barcode and loading.
- ☐ Record MOQ, payment, lead time, destination and Incoterm.
- ☐ List evidence and food-contact review responsibilities in the PI.
What Can the Evidence Actually Prove?
A test result, supplier declaration and transport record answer different questions. Ask the air fryer paper liner supplier to tie every document to the exact material, SKU, lot, method, facility, validity period and intended market. Neither source below certifies a Runjia product. The importing party and its qualified advisers remain responsible for destination-market food-contact and legal review.
| Authority source | What it supports | What it does not prove |
|---|---|---|
| ISO 16532-1:2008 — Grease Resistance Permeability Test | Defines a through-sheet grease-resistance test, including creased specimens. | Does not approve a finished air-fryer liner or appliance use. |
| ISO 16532-2:2007 — Surface Repellency Test | Defines a surface grease-repellency assessment. | Explicitly does not measure grease permeability through the sheet. |

Frequently Asked Questions
Is grease resistance the same as leakproofness?
No. Sheet resistance and finished-liner leakage are related but different questions.
Should folds be tested?
Yes, when the commercial product is formed or creased, include those features in the trial.
Can one appliance trial cover every basket?
No. Basket size, airflow and loading may differ; define the intended range.
Does a dry food trial answer an oily-food question?
No. Use a representative challenge for the claimed application.
What should appear on the RFQ?
State dimensions, shape, coating, pack count, intended use and the leakage acceptance protocol.
