Springs and compression washers often go unrecognized as the source of packaging problems on flow wrappers. This Greener Tech Bite explains how we helped a client discover and fix the weak springs that were causing poor seal quality. Read more
Diagnosing Packaging Problems – Part 2: Inconsistent Pressure & Leaks
In Part 1 of this Greener Tech Bite we diagnosed potential causes and solutions for the the splitting and fracturing in the upper left corner of this package.
Here in Part 2 we’ll diagnose problems with uneven pressure and leakers that can persist after adjustments and sealing jaw design changes have eliminated the splitting. Read more
Diagnosing Packaging Problems – Part 1: Split, Fractured Seals
When solving packaging problems, you’ll achieve the best results when you diagnose one symptom at a time and evaluate the effects of each corrective adjustment. This systematic approach will help you isolate the causes, determine the best solutions, and avoid steps that compound the problem and waste time.
In part 1 of this Greener Tech Bite we diagnose the most apparent problem on this package from a flow pack wrapper—the split in the upper left corner.
Adjusting Heat, Time, & Pressure: Quality Seals on Flow Wrappers & Vertical FFS Baggers
The right combination of heat, time, and pressure is required to produce quality seals on form fill seal baggers and flow wrappers. These sealing elements are closely linked; adjusting one can change the others and cause unexpected problems. This post reviews the function of and relationships between heat, time, and pressure, so you can better understand and anticipate the full effects of your adjustments. Read more
Knife Adjustment on Flow Wrappers: The Cost of Quick Fixes
When cutting problems delay production, quick fixes are often used to get flow wrappers up and running again. But instead of saving a few minutes of downtime, these shortcuts can cost you hours of production time.
This Greener Tech Bite identifies common quick fixes that bypass standard knife adjustment procedures. Their immediate and cumulative effects cause well over half of the cutting and sealing problems that we encounter. Read more
Pressure & Heat: Adjustments & Sealing Jaw Designs
This Greener Tech Bite reviews machine adjustments and sealing jaw designs that provide the pressure and heat* required for quality seals. You can consult additional, detailed posts and videos on each topic by clicking the red links or the corresponding images.
Quality seals on flow wrappers & vertical baggers require a combination of time, pressure, and heat, if utilized, that seals across varying thicknesses created by the fin or lap seal, gussets, or other pleats and wrinkles. Read more
Package Diagnostics: Case 1 – Sealing Jaw Design
This Greener Tech Bite is the first in a series of case studies on the Package Diagnostic Process.
When we work with clients, sample packages provide vital diagnostic clues for troubleshooting problems on flow wrappers or vertical baggers. And even when clients don’t report problems, we use sample packages to help them discover and implement improvements that they may have overlooked—from new knife, sealing jaw, and former designs to machine adjustments that optimize the whole packaging process.
Case Study: Resolve Cutting & Sealing Problems with Standard Operating Procedures & Training
One of Greener’s Technical Salespeople discovered that knife purchases by their customer had grown by 35% over the past year, at an additional cost of nearly $10,000. It seemed unlikely that additional production had accounted for all of this increase, which indicated to him that the customer could be experiencing problems on their horizontal flow wrappers.
Analyzing Sealing Jaw Carbon Impressions to Troubleshoot Problems on Flow Wrappers & Vertical FFS Baggers
In this Greener Tech Bite we analyze six sealing jaw carbon impressions and explain how each was used to troubleshoot problems on flow wrappers or vertical form fill seal baggers. Read more
Forming & Sealing on Vertical FFS Baggers: 6 Key Design & Set-Up Principles
This Greener Tech Bite, with the help of our partner Kenray Forming, explores six key design and set-up principles to help you identify the source of forming and sealing problems and develop solutions for quality packages. Read more
