Are You Paying Too Much for a Sealed Package?


How to Calculate the Value-in-Use of Packaging Films, From a Packager’s Perspective

Packaging films made with a high-performance sealant resin, such as DuPont™ Surlyn®, often can be used at faster line speeds, with fewer rewraps or losses due to package failures (“leakers”) in transit and at retail. The DuPont Packaging Sealant Value Estimator (SaVE) helps brand owners and converters evaluate the total costs of flexible packaging that relies on sealing solutions to help protect the contents.

SaVE allows you to:

SaVE makes the following assumptions:

  • The packing line is sold out; increased efficiencies (higher line speed and fewer rejects) result in either more product being sold, or other products packed on the line so that overhead and equipment costs are constant.

  • Increased line speeds can be achieved; the packaging line is not bottlenecked by factors other than sealing speed.

  • Labor for re-wraps is accounted for in the number of employees per line.
