You’ll find that stickers and labels are used for a variety of reasons. They can be used as a decorative element to strengthen branding or to convey critical information such as ‘flammable’ or ‘fragile.’
Informational labels are effective in making a strong first impression as you’ll commonly see them on the exterior of boxes and customers take notice of them before the unboxing.
Decorative stickers are usually used inside packaging, for example, to keep tissue wrapping in place and add an extra touch.
