Springs & Compression Washers: Seal Problems & Maintenance on Flow Wrappers
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.
Prevent Problems & Maintain Productivity with Carbon Impressions
Carbon impression are most often used to guide the setup of sealing jaws and to solve problems on flow wrappers and vertical form fill seal baggers.
But Carbon impressions should also be taken before each new production run and when variables such as product size or packaging materials change. These extra impressions will indicate ongoing adjustments and preventative maintenance that prevent package quality problems and lost production time. Read more
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
