Food packaging symbols answer several different questions. The glass-and-fork mark concerns food contact; recycling labels explain disposal; an FSC label concerns the sourcing of forest-based materials. A pack can carry all three because each describes a different aspect of it.

For a brand creating packaging for the UK, the crucial detail is which component each mark covers. A paper gift box, its inner bag and its tray may need different information. Read the symbol together with its wording and component name to understand the claim being made.

The glass-and-fork food-contact symbol

The symbol showing a wine glass and fork identifies a material or article intended for contact with food. The labelling rules reserve this indication for materials and articles that meet the applicable food-contact requirements. Supporting documentation connects that short message to a particular material and its intended use.

It is not a symbol that must appear on every food pack. For materials and articles marketed before they are in contact with food, Article 15’s labelling provisions allow the words for food contact, a specific indication of use such as soup spoon, or the prescribed symbol. That particular indication is unnecessary where an article’s characteristics make its intended food contact clear. Necessary instructions for safe and appropriate use still matter.

Food-contact suitability depends on the conditions. A lining intended for cool, dry biscuits may need a different specification from one holding warm, oily pastries. Food type, contact time and temperature help determine the appropriate material and evidence. Coatings, inks, adhesives and barriers also make the finished construction relevant.

When sourcing packaging, ask for compliance documentation appropriate to the material and intended use, including a declaration of compliance where required. A useful specification identifies the food, filling conditions, storage and any heating involved, so the supplier can assess the actual application.

Microwave, freezer and storage markings

A microwave outline or wavy lines commonly signals microwave use. A snowflake may indicate freezer suitability or refer to frozen storage. Designs vary, so the accompanying words establish what the pictogram means for that particular pack: which component it concerns, how it should be prepared and any temperature or time limits.

For example, a ready meal’s directions may require removing the cardboard sleeve and piercing the film before heating the tray. Those components have different jobs during cooking. The microwave symbol belongs with that complete instruction, rather than giving permission to heat every part together.

Date wording supplies another part of the message: use-by concerns food safety; best-before concerns quality. Read either alongside the storage conditions and any instructions for use after opening. A freezer pictogram alone does not tell you how long the food can be stored.

Traffic-light nutrition labels and printing dots

On a UK front-of-pack nutrition panel, red, amber and green indicate high, medium and low levels respectively for nutrients such as fat, saturates, sugars and salt. Read the colours alongside the numerical amounts and serving information. These colours help explain the food’s composition.

Small coloured dots or squares elsewhere on a pack may be printing control marks. Printers use these patches to check colour reproduction and print consistency. Their position near a seam or flap, and their separation from the labelled nutrition panel, help distinguish them from information about the food.

Recycling and disposal symbols used in the UK

Several marks use arrows, but their meanings differ substantially. Some identify a collection route, some describe a material and others communicate a producer’s participation in a scheme. Recycle Now’s UK symbol guide makes these distinctions particularly useful when interpreting a mixed-material food pack.

The common plastic codes are 1 PET, 2 HDPE, 3 PVC, 4 LDPE, 5 PP, 6 PS and 7 Other. They identify materials rather than rank their recyclability. Even within one plastic type, the shape, size and construction of a bottle, tray or film can affect collection and sorting. The finished packaging item is what needs a suitable disposal instruction.

Read the component name and action together

OPRL stands for On-Pack Recycling Label. Its assessments consider UK collection availability, sorting, reprocessing and markets for the resulting recycled material. The words alongside the label translate that assessment into something the person holding the pack can do.

• Rinse or scrape: remove food residue as directed. The appropriate action depends on the component; paper and card should not simply receive the same cleaning instruction as a plastic pot.
• Cap on or lid on: keep the specified closure with the main item. Small closures can be lost during sorting when separated.
• Remove film or remove sleeve: separate the indicated part, then follow its own disposal instruction.

A dessert pack might identify its card sleeve, plastic pot and film lid separately. The sleeve and pot could have recycling instructions while the film has a different destination. The panel is describing several components, not giving one verdict on the assembled pack.

For a brand developing that structure, the physical separation needs to work too. An instruction to remove a sleeve is useful only when someone can recognise the sleeve and remove it as intended. That is a detail worth checking on the sample, alongside the artwork.

If a label says Check Home Collections, confirm acceptance with the local collection service. When instructions are missing or unclear, Recycle Now’s postcode-based Recycling Locator can help identify the appropriate route. An unlabelled item may still be recyclable.

Compostability marks: check the intended setting

The Seedling logo identifies a product certified as industrially compostable to EN 13432. This means composting under controlled conditions, including temperature, moisture and time. The mark may be used only for a formally certified product.

Industrial compostability and home compostability are separate claims. For a home-composting claim, look for an appropriate separate certification, such as OK compost HOME, and follow its product instructions. The Seedling mark alone does not establish suitability for a garden compost heap.

Certification describes how the product can be treated; collection acceptance determines whether that treatment is available. Check whether the relevant food-waste or garden-waste service accepts that particular compostable packaging. Keep compostable plastics out of ordinary plastics recycling. If no accepted composting route is available, follow local waste guidance.

This distinction can change the packaging choice. A food outlet with a dedicated collection arrangement may have a workable route for a certified compostable component. A retail pack taken home needs disposal instructions that remain useful after it leaves the shop.

FSC labels on paper and board

The FSC tick-tree label concerns the sourcing of forest-based materials. On paper food packaging, the wording beneath the logo identifies the relevant sourcing category. FSC distinguishes three labels:

FSC Mix does not state one fixed recycled-content percentage. Equally, an FSC label on an outer carton does not automatically extend to a separate liner or insert. Make clear which packaging element the label covers. Its claim concerns forest-based material sourcing; food-contact suitability and disposal still need their own evidence and instructions.

If you want an FSC label on a printed food box, specify that requirement at the outset and arrange production and labelling under a valid FSC chain-of-custody certificate. In the usual commissioning route, the certified printer or packaging producer provides the authorised artwork and manages the required approval. Check that the certificate covers the relevant product and that the sales documents identify the certified packaging and claim. FSC UK’s purchasing guidance explains these checks.

A food brand simply filling finished, FSC-labelled packaging, without transforming or relabelling it or adding forest-based components, does not normally need its own chain-of-custody certification. Separate use of FSC trademarks in marketing has its own permission requirements. A promotional licence does not itself authorise applying an FSC label to a product.

Putting the right symbols on a new food pack

At CMIC, we can help turn these distinctions into a clearer packaging specification. For a paper food gift pack, a useful early result is a component map: outer box, inner wrap, tray or insert, and closure. Against each part, we can work through its purpose, relationship with the food, material and intended disposal route. That gives the design team a reason for each symbol and identifies where material evidence, testing or scheme approval is needed.

These decisions can affect the structure itself. If a bonded window complicates disposal, a separable component may be worth assessing. If a proposed compostable liner has no accepted collection route, another material may be more practical. Resolving those questions during material selection and sampling gives the artwork a sound basis.

For packaging manufactured in China and destined for UK shops, the disposal instructions should reflect the UK destination. Manufacturing origin does not determine which collection system the customer will use.

You can start with an existing pack, a product photo or an early structural idea. Talk with us about your UK food packaging, including how the food will be packed, stored and used. We can help develop suitable paper packaging and coordinate the material information and labelling decisions around those conditions.
