What will you learn at Packworx?


Learn the lingo.

All the basics! Learn how stretch film is made, the different types and their best applications. Understand containment properties and how they apply to different sized and weighted pallets. Master stretch film key words and phrases. Become the go-to expert authority in all your customer relationships.


Evaluate the situation.

Learn how to evaluate a customer's packaging process, identify the pain points and provide solutions that often use less film to produce higher containment. Document their current process and explain opportunities for improvement.



Determine the exact number of revolutions, type and gauge of film, and level of prestretch needed. This often uses less film for better containment, saving cost and reducing environmental waste. Optimal containment also reduces the amount of product damaged in transit, saving costs due to goods destroyed in transit.
