シュリンク包装
A plastic film that is used to wrap something (very often a product for sale).

When heat is applied to it, it shrinks to conform to the product inside. This is often done to hold food onto a [[tray]] in [[food packaging]], or when done to another [[container]] (such as a [[medicine]] [[box]], [[cd case]], or [[video game]] [[box]]) to be tamper-evident for safety or prevent theft. It is also used on [[book]]s and [[manga (object)|]] either to prevent minors from viewing adult content or to prevent shoppers from reading in a store without purchasing.
