This Greener Corporation “Tech Bite” provides a Troubleshooting Checklist for working with us to solve packaging problems on horizontal flow wrappers. Answers to the checklist questions will allow us to help
define your problem, determine the causes, and develop solutions that restore package quality and productivity.
With this video and blog post as a guide, you can start the problem solving process by
contacting Greener Corporation or by filling out our online Troubleshooting Checklist.
You may not have immediate answers for every question; just provide as much information as possible. Our technical staff will request any additional details that they need.
1. Define the Problem
Do your packages have leakers?
Are there package appearance issues such as crushed or split end seals, wrinkles, creases, or heat distortion?
You might be experiencing both.
Is the problem isolated to one wrapper, or does it occur on multiple machines?
What is the make and model of each wrapper?
Are results the same on every shift? Does the problem occur at more than one plant location?
Try to determine when the problem began, and note any changes that might be contributing factors.
Has the film structure, film supplier, or the product changed?
Have there been changes with personnel, or with tooling such as crimpers, knives, fin wheels, or heaters?
Let’s further clarify when and where the problem exists.
Is the leak or appearance issue always in the same location on the package?
Does the problem occur on every package, or intermittently?
If using a multi-crimper sealing head, does the problem occur on every pair of crimpers?
Track the problem to see if it appears on the leading seal, the trailing seal, or on both.
For multi-use machines, does the problem occur consistently, or only with one package size, product, or film structure?
How have you already tried to solve the issue? What was the result?
2. Determine Causes
Send clear photos of carbon impressions—our most important diagnostic tool. They reveal vital, otherwise hidden details about machine set up and condition, crimper and knife design, and other causes.
Provide photos and samples of packages, run during production, that demonstrate your problem. Also include, if possible, the film specifications and the name of the film supplier.
Provide photos or videos of any machine processes or components that are pertinent to the problem, such as: crimpers; used anvils and knives, and the sealing and cutting head.
Are your knives adjusted with screws or shims? If shim adjusted, what is the number and thickness of the shims under the knife and anvil?
Using a contact pyrometer, provide three temperature readings from the crimper sealing face—in the middle and on each side where the outer edge of the package contacts the face.
Provide wrapper control settings, if available, for line speeds, dwell, package length, and for the temperature of the crimpers and fin wheels.
3. Develop Solutions
Every detail, even those that seem insignificant, provides clues that will help us develop effective solutions to your packaging problems.
