Start with the sensory question you need answered
A snack buyer may receive a report headed “odor test” without knowing which question it answers. Ask the issuer to identify the evaluated sample and the decision the report supports before comparing suppliers. A result for unprinted film should not silently become approval of a differently printed, laminated and converted pouch.
Use three questions in the project brief: What was noticed from the packaging itself? Was transfer evaluated in a defined test system? What evidence addresses the intended food in the finished package? These questions help assign work without treating every concern as the same test.
Read the method scope before accepting the conclusion
ASTM E1870-25 describes sensory evaluation of polymeric packaging films, including assessment of their inherent odor and transfer to a model system. Its public scope calls for trained sensory evaluation and covers a single time point; it excludes shelf-life testing.
Ask a qualified evaluator to explain the report’s criteria and limitations in terms your QA team can use. Do not create an informal taste test for a suspect product. Absence of a noticeable odor is not proof of chemical safety, and a sensory result should remain separate from the food-contact document review.
Build a three-question evidence worksheet
This is a suggested buyer worksheet, not a prescribed laboratory form. Give every attachment a sample reference so that a reader can follow the conclusion back to the specimen.
| Buyer question | Record to request | Unanswered question to retain |
|---|---|---|
| Packaging’s own odor | Film or pouch identity; printed/laminated state; sample age; evaluator and method | Does this describe the proposed production construction? |
| Transfer in the test system | Contact arrangement, medium, exposure conditions and assessment criteria | How does that test system relate to the intended food? |
| Actual food during storage | Filled-package study plan, food identity, storage conditions and assessment owner | What further evaluation is needed before release or a shelf-life claim? |
| Approval boundary | Report date, specimen revision, exceptions and named decision owner | Which uses or revisions remain outside this approval? |
Check the handoff between film, pouch and filled product
For an illustrative dried-snack launch, procurement might have a film screening report while the co-packer is still choosing the final printed pouch. Record that gap explicitly: the report is useful background, while applicability to the final construction remains an open item. Ask the quality owner to decide whether additional evidence is needed before placing the production order.
Keep both the report and the packaging revision in the approval record. If a construction, print system or food-contact use changes, route the change back to that owner. The purpose is to avoid reusing an old conclusion for a new specimen, not to prescribe an identical test program for every food.
Turn the remaining gap into a supplier request
Send the product description, pouch dimensions, proposed construction or supplier reference, artwork status, filling conditions and intended storage use. Add the exact unanswered sensory question, the report already available, and who will evaluate the response. Ask separately about representative samples, the testing party, costs and timing; availability of a pouch sample does not establish that a particular test service is included.
