Health & beauty labels are often to be found in humid environments, eg bathrooms. As such these labels need to be water resistant. In addition, they are often applied on squeezable containers (like a shampoo bottle) which creates an additional requirement of deformability and of course, the print on the label has to remain readable. As substrates, typically co-extruded or PE facestocks are used for this type of labels. Self-adhesive labels as such (aka ‘pressure sensitive labels’ or PSL) are made by printing onto a laminated construction of 3 layers: a release liner
(otherwise known as the backing paper, carrier or glassine), a layer or adhesive and the facestock material. The laminate is printed and then converted in a roll containing the requested number of labels per roll. A web-fed process brings a high label application speed on the packaging line and allows for more embellishing processes. In addition, its flexibility of application is enormous, either during or after the filling process and on any type of surface/container just by taking another glue.
