[Dior Project] Karlville Delivers Optimal Shrink Quality & Placement Accuracy

Discover how Karlville transformed Christian Dior’s shrink process by providing automatic container orientation for high sleeve placement accuracy and our Tornado hot air tunnel for high shrink quality.

The Dior Project Overview

Christian Dior had a sleeving line for these boxes equipped with manual application and a shrink laydown with a competitor IR tunnel.

They wanted to increase the capacity and automatically apply the sleeve, but a test done with the existing tunnel didn’t offer the expected quality.

Karlville, well-known thanks to its Tornado tunnel, was challenged for this application that required a premium level of shrink quality and sleeve placement accuracy.
