Packaging that touches the food

Packaging is not just another consumable: it carries its own paperwork, and it is approved for one use, not for any.

Updated on 13/08/2026

When people think of a food product's paperwork they think of ingredients. Packaging is bought the way labels or detergent are bought, and it enters the conversation the day an auditor asks which document backs that tray.

What the packaging supplier must give you

DocumentWhat it saysWhen to ask
Declaration of compliance for the materialThat it is suitable for food contactWhen approving the supplier
Which use it is declared forFatty, acidic, dry, hot, frozen…Before deciding which product it holds
Technical sheet for the materialComposition, weight, layersAlong with the declaration
A current version for every changeIf the material changes, the paper changesWhenever the supplier changes anything

Important

The second row is barely ever read and invalidates the most declarations: **suitability belongs not to the packaging but to the packaging for a specific use**. A bag declared for dry product at room temperature stops being backed if you put something fatty in it, or if it goes in the oven or the freezer. The document is still correct; what no longer fits is your use. And nobody spots that mismatch until someone compares the declaration with what is inside.

What to check before switching packaging

  1. 1

    What it is declared for, not just whether it is «food grade»

    «Suitable» on its own says nothing: read what for.

  2. 2

    Whether your product fits that use

    Fat, acidity, temperature and contact time are what decide.

  3. 3

    That the change does not affect the label or shelf life

    A different material can change how the product holds up.

  4. 4

    And file the declaration with the date it came into use

    That is what ties each batch to the packaging used.

Watch out

A silent change that catches many out: **the supplier can change the material without changing the reference**. Same code, same look, a different film supplier, and the declaration you have filed no longer matches what you are using. So it is worth asking for version confirmation at least yearly and whenever you notice any difference — a different shade, another stiffness, a seal that behaves differently.

If you pack for others

Worth knowing

Which requirements apply to each food-contact material, what the manufacturer must declare and which tests are required depend on food contact materials regulations and on the destination market. **Your adviser or quality manager confirms that**; here it is about the paper existing and matching the real use.

Is the distributor's declaration enough?

If it is the manufacturer's, yes. An email saying «it is food grade» is not.

Must every version be kept?

Yes: the one valid when that batch was produced is the one you will be asked for.

What about packaging that only groups items?

Lighter requirements, but be clear which touches the food and which does not.
