The Fallacies of Foam in Place

Foam in place, or FIP, is widely used and widely misunderstood. FIP is marketed as a safe and efficient in-the-box packaging solution.

We disagree.

Join us as we explore the realities of FIP from several standpoints. We will compare FIP to sustainable, recyclable paper alternatives that are better for your business, better for your margins and better for the environment.

What is FIP?

FIP is a term for packaging systems where two liquid urethane chemicals are sprayed into a film that will surround the item being shipped. When the “A” and “B” chemicals meet, they expand to fit around the item inside the box. The primary chemicals used in FIP are petroleum based and unhealthy for both people and the environment.

Cost Comparison

On average, Ranpak solutions reduce costs by at least 20% compared to Foam-in-place. 


Ranpak paper-based packaging solutions are 100% recyclable, renewable and biodegradable.

Waste and Mess

Dual Impact on the Environment

Is FIP safe? It requires plastic film, solvent, drums, drum removal and protective clothing.


Paper Versus Foam in Place, An Economic Case Study

In a recent cooperative study involving Ranpak and a major shipper, we tested Ranpak paper-based solutions against the foam system currently being utilized. For the test, we used Ranpak’s SR and Auto Coiler. Our goal was two-fold: to clearly demonstrate cost savings efficiencies using Ranpak paper, and to show the ease of operation. A Ranpak engineer with 20 years of product experience, and an associate employee of the shipper with only 9 hours of experience on the same equipment, each packed 8 boxes with identical product. The Ranpak engineer achieved a 19.6% savings on materials cost compared to foam and the less experienced associate showed a 17.0% savings, for an average savings of 18.3%. In addition, through process improvements and pack standardization, Ranpak’s SR and Auto Coiler provided a 15.0% increase in output of units per hour!

This is a substantial cost savings in materials and higher output, and the economic efficiency of paper versus foam speaks for itself. Again!
