Medical device labelling is one of the most information-dense regulatory environments in any product category. A single device placed on the Great Britain market in 2026 may need to carry: the UKCA mark or CE mark (or both), the UK Responsible Person’s name and address, the manufacturer’s details, a Unique Device Identifier, batch or lot number, manufacturing date, expiry date where applicable, instructions for safe use, warnings, the applicable conformity standard, and — for devices supplied across both GB and EU markets — the EU Authorised Representative’s details alongside the UK RP.
On a small medical instrument, a diagnostic consumable, or a single-use sterile device, accommodating this information on a standard single-layer label is frequently impossible without compromising legibility.
Booklet labels provide a directly applicable structural solution. These multi-layer constructions attach to the device or its primary packaging and present additional printed pages that can be accessed by the end user. The outer panel carries the most immediately safety-critical information, such as device name, conformity marks, batch number, and expiry date, at a size and contrast that meets regulatory legibility requirements. Inner pages carry the extended mandatory content: full Instructions for Use, warning statements, multi-language declarations for devices distributed across multiple territories, and regulatory reference information.
Why Medical Devices Specifically Need Extended Label Formats
The Instructions for Use obligation under the Medical Devices Regulations requires that IFU is provided in a language easily understood by the intended user in the country of supply. For a UK manufacturer supplying devices into five EU member states, the IFU must be provided in the local language of each territory.
Where the IFU is included within the device packaging rather than provided as a separate document (common for single-use, sterile, or implantable formats where secondary packaging space is limited) the booklet label is frequently the only format that allows language-complete IFU without enlarging the packaging.
The dual-marking scenario adds further pressure. Where a device carries both CE and UKCA marking, the UK Responsible Person and the EU Authorised Representative must both be identified on the label. Both conformity marks must appear with correct format and, where a UK Approved Body or EU Notified Body was involved, their identification numbers must appear adjacent to the respective mark.
A Class IIa medical device dual-marked for GB and EU supply, with multi-language IFU, can easily require more mandatory label content than a standard single-layer label on its primary packaging can accommodate.
For device manufacturers reviewing their labelling architecture ahead of future MHRA transitional deadline dates, booklet label specifications should be assessed now, particularly for devices where the primary packaging format is fixed and cannot be enlarged. Lead times for booklet label tooling, print approval, and regulatory documentation review make early engagement with a specialist label supplier the operationally sound choice.
