Multi-layer or leaflet labels are increasingly used in situations where standard labels are inadequate, but as Chris Lindley-Smith of Newman Labelling Systems reveals, they can lead to application issues.
Dual or multi-layer labels are commonly known as leaflet labels, booklet labels or fix-a-form labels and are constituted from a single- or multi-page leaflet (sometimes up to 40 pages) incorporated on top of a self-adhesive label with another self-adhesive cover. They are increasingly being used for applications where the product space available is inadequate for presenting the required information on a standard label format.
From a pharmaceutical industry perspective, multi-page labels have been especially noticeable, as strict regulatory control has increased the need for more product information, often in multiple languages.
Leaflet labels are commonly found on a variety of pharmaceutical products including over-the-counter (OTC) medicines, prescription-based solid dose products, clinical trial products and unit dose injectables. The production of these products requires the application of such leaflet labels onto glass and plastic bottles, square pots, vials and even ampoules.
In practice, these labels can cause production problems for many automatic application systems, as their initial design did not consider the use of anything other than a single-ply label.
