Shrink wrap packaging films

One of the most important things that need to be decided in a shrink wrap packaging project is the type of film to be used. Film choices are made based on percentage of shrink needed, desired finish(gloss/matte), application considerations, and so on. Before choosing a film for a project, the shrink label supplier needs to calculate the shrink percentage needed to conform to the container. This is done by determining the smallest diameter in contrast to the widest circumference. It  is reported in percentage of total shrink needed to encompass the cut height of your container. In order to understand the choices we will cover their advantages and disadvantages.
