Sampling & validation

Test a candidate against the application that matters.

Share the bottle, contents and current sealing conditions so the sample requirement can be discussed. Testing should reflect actual use conditions.

When to review

A sample review is usually needed when conditions are new or changed.

New customer or specificationNew bottle or applicationNew or changed sealing equipmentChanged use conditionsConcern affecting a previous solution

An unchanged, previously confirmed application may take a shorter route after its key conditions and validity are checked.

Two bottles used to review sealing applications — Actual bottle context

Prepare information

Follow the diagnostic order.

Unknown is acceptable. Mark it clearly instead of replacing it with an assumption.

ContentsWhat is actually inside the bottle?
Current sealing methodHow is the bottle sealed today?
Current liner and issueWhat is used, and what needs to change?
Container materialIdentify the bottle material, not only the cap.
Bottle-neck informationDimensions, drawing, clear photos or a sample.
CustomizationPrint, embossing, opening features, format or specified material.

Testing responsibility

Agree who can test under actual conditions.

Customer or actual user

Carry out or coordinate the test using the actual bottle, contents and process, then confirm the result.

CY Seal

Match candidate samples to available information, provide relevant guidance and help review anomalies.

If the actual user is another party, agree how test conditions and feedback can be shared without unrelated confidential information.

Final confirmation

A dispatched sample is not a confirmed solution.

Actual-condition test accepted+Final specification agreed=Confirmed solution

New information or a change to key conditions may require another review.

Test result: The accepted result is recorded against the confirmed specification version, together with the material and structure, the bottle-neck specification, the quantity and the customization requirements.
Production version: Production follows the latest confirmed version. A change after confirmation needs written agreement and creates a new version; the previous version no longer applies.

Confirm the sample arrangement before it starts.

Quantity, preparation, shipping, charges and the target timing are confirmed for the project. No universal free-sample or lead-time promise is implied.
