Why Perforations Are Used in Shrink Sleeve Packaging
There are few things more frustrating for a consumer than being unable to easily open a package — in many cases, poorly perforated safety seals are the culprit.
Perforations on shrink sleeves perform a number of functions. On neck bands, perforations make it difficult to open or tamper with a product without it being obvious to the consumer. They allow the top portion (tamper-evident band) of a full-body label to be removed from around the cap, leaving the primary graphics remaining on the body of the package. Perforations can also be used to make it easy for the customer to remove the sleeve for recycling purposes.
The primary perforation types are: full vertical, horizontal and partial vertical, and venting.
