This article provides an overview of shrink sleeve substrates, their uses, and how to choose them. We will not have hard and fast rules, but will instead provide advice and guidance to practitioners as they embark on the shrink sleeve label production journey.
Heat shrink substrates are comprised of a number of polymers. The most common include OPS (Oriented Polystyrene), PVC (Polyvinyl Chloride), PETg (Polyester) and Polyolefins. Additionally, combination films, Hybrid or Multilayer films, and speciality films like White Opaque (Figure 2.1) also round out the substrate offerings. This list is not exhaustive, but it does give a sense for the breadth of options that exist. Each film has different properties and characteristics that require consideration when choosing the most appropriate solution.
