Labels & Stickers

Labels and stickers are a deceptively important part of food service operations. They carry allergen information, best-before dates, ingredients, portion weights, and brand identity. Get this wrong and you face food safety compliance failures or recalls. Get it right and a well-designed label on a plain white container can look sharper than badly printed bespoke packaging. For food businesses buying labels in volume, the key variables are the label stock, adhesive type, and how the labels will be applied and printed.

Key Factors to Consider

Label Types and Substrates

The substrate is the material the label is printed on or written on. Common options in food service:

• Paper labels (white or kraft): The standard for most food labelling. Suitable for ambient and refrigerated products. Not suitable for wet surfaces or where condensation is a regular issue.
• Polypropylene (PP) or polyethylene (PE) film labels: Waterproof and more durable than paper. Better for chilled products, any container that might get wet during service, and products stored in ice or high-humidity environments.
• Removable labels: Use a low-tack adhesive that leaves no residue. Useful for containers or packaging that is reused, or for chilled display items where the label needs to be changed daily.
• Freezer labels: Use a specialised adhesive that bonds at low temperatures. Standard paper labels will fall off in a freezer or from a frozen surface within minutes.
• Direct thermal labels: Designed for use with thermal label printers (no ink or ribbon required). The most common format for date coding and allergen labelling in food service. Compatible with Zebra, Brother, Dymo, and similar printers.

Size

Label size needs to match the surface area of the container or packaging it will be applied to. For deli pots, round containers, and cups, a label that wraps around more than about 70% of the circumference will not lie flat unless it is specifically designed for that format. Common catering label sizes:

• 50mm x 30mm or 70mm x 36mm: small deli pots, sauce bottles, spice jars
• 100mm x 75mm or 102mm x 51mm: sandwich packaging, larger containers
• Full-face A4 sheets (individual labels): large trays, catering display items

For direct thermal printers, standard rolls are typically 50mm x 30mm, 57mm x 32mm, or 102mm x 76mm. Confirm your printer's compatible roll sizes before ordering.

Adhesive Performance

The adhesive needs to match the application temperature and surface type:

• Standard permanent adhesive: Works on dry surfaces at room temperature. Will fail in cold or wet conditions.
• Refrigerator/deep-freeze adhesive: Formulated to bond to cold surfaces and stay bonded through temperature cycling.
• Peelable or repositionable adhesive: Removes cleanly without residue. Important for reusable packaging.
• High-tack adhesive: For difficult or low-energy surfaces such as polyethylene bags.

Buying a label with the wrong adhesive for your application results in labels falling off in the chiller or leaving residue on containers -- both create operational problems.

Allergen and Compliance Labelling

Under Natasha's Law (UK, from October 2021), all pre-packed food for direct sale must carry a full ingredient list with allergens highlighted. This requirement affects most grab-and-go, pre-packed sandwich, and deli operations. Labels used for allergen compliance need to carry enough information in a legible font size (minimum 1.2mm x-height for mandatory information under EU and retained UK regulations). Ensure your label size and printer resolution are adequate for the text required. If you are unsure about your specific labelling obligations, the Food Standards Agency publishes current guidance.

Printing: Pre-Printed vs Thermal Print-Your-Own

Pre-printed labels with your brand, product name, and fixed information are cost-effective at volume (typically 1,000 units minimum, with significant discounts at 5,000+). Variable information (dates, weights, prices) is then added with a stamp or thermal overprint.

Direct thermal print-your-own is the most flexible option for date coding, allergen information, and prices that change regularly. A thermal label printer (£80 to £400 for a good commercial unit) and compatible label rolls gives complete control. Running cost is typically £0.01 to £0.03 per label at commercial roll prices.

Cost and Value

Blank direct thermal label rolls (57mm x 32mm, 1,000 labels per roll) typically cost £1.50 to £3.50 per roll, or less at case quantities. Pre-printed branded labels start from around £20 to £50 per 1,000 for simple designs at reasonable volumes. Freezer or waterproof film labels carry a 30 to 80% premium over standard paper equivalents.

Pro Tips

• If you are using a thermal label printer for date coding, invest in a commercial-grade printer rather than a consumer model. A printer that jams or misfeeds during a busy prep session is a significant disruption.
• Test label adhesion on your actual packaging materials before ordering in volume. Paper labels on recycled kraft board, coated PP containers, and aluminium foil all behave differently.
• For chilled display items, use removable labels so that the date can be updated each day without damaging the container. This is especially relevant for deli pots and sandwich boxes that are refilled daily.
• Keep a small stock of blank A4 label sheets for emergency reprinting of large format allergen information or daily specials. Inkjet-printable versions are inexpensive and widely available.

Summary

Labels and stickers are a compliance-critical purchase in food service, not just an aesthetic one. Match the substrate and adhesive to the temperature and surface of your application, ensure your label size meets legal text requirements for allergen information, and invest in a reliable thermal printer if you are date-coding regularly. Pre-printed labels add brand consistency at volume; thermal print-your-own offers daily flexibility. Most operations need both.
