Shrink sleeve labels are made by printing a foil sleeve - usually PVC, PET or OPS. Under the influence of heat, they take the shape of a package to which they adhere tightly. The foil is usually printed on the inside, which makes the print resistant to scratches and abrasions.
Labels of this type can adhere to the entire surface of the package (full body label), which allows the maximum use of the printing surface. In this case, the sleeve also protects the contents of the package against UV radiation.
The labels for creating combo pack labels are also widely used for promotions, giveaways or samples.
