When cutting problems occur on horizontal flow wrappers during a production run, what are the best procedures to get packaging lines up and running again and to keep them running? Minimizing downtime, producing consistent quality packages, and managing costs require a balanced approach that includes:

Knowing which “quick-fix” adjustments will get knives cutting without causing additional problems and downtime. (Faster and easier is not always the best solution.)
Broad-based, P³ Solutions that consider the entire packaging process to:
• Understand how each adjustment affects the whole system.
• Eliminate procedures that don’t work.
• Diagnose and correct the ultimate causes of problems. (Many issues stem from a combination of factors.)
• Implement solutions that help prevent cutting problems from occurring in the first place and help you Pursue Zero.
