# 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._

**Responde a:** food contact declaration of compliance · food grade packaging paperwork · food bags documentation · the auditor asks for packaging papers

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

| Document | What it says | When to ask |
| --- | --- | --- |
| Declaration of compliance for the material | That it is suitable for food contact | When approving the supplier |
| Which use it is declared for | Fatty, acidic, dry, hot, frozen… | Before deciding which product it holds |
| Technical sheet for the material | Composition, weight, layers | Along with the declaration |
| A current version for every change | If the material changes, the paper changes | Whenever 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. **What it is declared for, not just whether it is «food grade»** — «Suitable» on its own says nothing: read what for.
2. **Whether your product fits that use** — Fat, acidity, temperature and contact time are what decide.
3. **That the change does not affect the label or shelf life** — A different material can change how the product holds up.
4. **And file the declaration with the date it came into use** — That is what ties each batch to the packaging used.

> [!WARNING]
> 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

**En corto**

- Your client will ask for the packaging documentation just as for the product's.
- And if they choose the packaging, get their declaration: you still need it on file.
- Secondary packaging, which does not touch the food, has lighter requirements but still gets justified.

> [!NOTE]
> 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.

## Ejemplos

**A food workshop starts packing fatty product in bags declared for dry goods.**

- Checks which use the packaging is declared for before switching product

→ The packaging stops being a finding waiting for someone to compare two documents.

**Packaging is bought without its usage documentation.**

- Requests it on the purchase order

→ The packaging arrives with what covers it.

**Packaging is used for a product other than intended.**

- Checks what use it is declared for

→ The decision is taken with the document in view.

**The maker changes the material and nobody knows.**

- Asks them to communicate any change

→ The change arrives before the question.

**A client asks for the packaging documentation of one run.**

- Checks that reference's file

→ You answer per run.

**Packaging documentation expires without warning.**

- Records validity on receipt

→ The warning arrives before the next purchase.
