Wrapped or direct fill
Identify the primary pack, contact layer and whether contents can migrate to the tube.

Food contact, inner packs and paper tubes
An outer tube around wrapped food has a different evidence burden from a direct-fill container.

Protein powder: sealed primary pack or direct fill?
A paper outer tube can present an already sealed powder pouch or separate container. A direct-fill powder pack needs a defined contact layer, seal and repeated-opening system. Specify fill weight, powder behavior, humidity and oxygen-control objectives, storage conditions and target-market evidence before agreeing construction. A photographed composite can does not establish a barrier level or food-contact approval.
| Decision | Information to supply | Review before approval |
|---|---|---|
| Primary pack | Sealed pouch, separate container or direct fill | Every layer touching the powder |
| Opening and storage | First-opening seal and reclosure frequency | Moisture/oxygen objectives and the intended storage conditions |
| Validation | Target market, filling process and packed weight | Material documents and filled-pack tests for the actual system |

When does a paper tube need food-contact evidence?
Map every surface that can contact the contents, including liners, lids and seals. Request market-specific material and migration evidence where contact exists; a photo or generic certificate is insufficient.
