What is shrink-wrapping?
Shrink wrapping is a process that uses relatively soft polyolefin film in which a loose sheath of film is created around the product, sometimes sealed on two sides. The loosely sheathed product passes through a heat source, which shrinks the film to the dimensions of the product. The result is a very tight wrap, conforming to the product shape, often with a ridge of plastic around the perimeter of the product or gaps in film on either end. Shrink wraps are typically stronger than overwraps and the machines are inherently very flexible. The downside is that shrink wraps can be less attractive than overwraps. Shrink is a great solution when the product is oddly shaped or you are doing a low volume of any one size package. Operational costs are typically higher because of film waste and energy consumption in the shrinking process. Products must be heat tolerant due to the required heat tunnel to make the film fit the package. You usually cannot use printed film as the film often distorts
Cellophane like wrapping that we heat shrink to protect your books. This is done around the finished books before boxing. The books can be shrinkwrapped in groups or individually. If you have a matte lamination with dark print, Thomson-Shore highly recommends shrink wrapping to protect the cover or jacket from marking due to the soft nature of matte lamination.
