Need a Flexible Packaging Calculation? Try our New Online Tools!

PennPac has developed a free library of calculators and converters to determine the amount of flexible packaging film you’ll need for your next project.

This new resource provides a number of helpful online tools, including a roll OD calculator, metric-to-standard converter, and more:


  • Thickness
  • Yield
  • Seal Strength
  • Tensile Strength
  • Oxygen Transmission Rate
  • Water Vapor Transmission Rate
  • Metric to Standard


  • Outside Diameter of a Roll
  • Weight of a Roll
  • Footage on a Roll
  • Length-Width of a Roll

You can access the tools anytime from the flexible packaging films page or from the new Resources section located in the main navigation of our website. You can also now access our spec sheet library under this section.

Figuring out your flexible packaging calculations has never been easier! If you have any questions or need assistance crunching numbers, contact our team.
