Is Recycled Worth It?
Standard Pristine Foil:
• ~ $0.047/sq ft
• 3-4% strain at failure
• 60-80 MPa maximum stress
• Lower Young’s modulus
• Requires 88% less energy to make
• ~ $0.085/sq ft
• 2% strain at failure
• 100-120 MPa maximum stress
• Higher Young’s modulus
Which Foil Wins?
• Pristine Foil Wins: • Recycled Foil Wins:
– Corrosion resistance – Oxidation resistance
– Consumer cost – Tensile strength
– Strain tolerance – Eco-friendliness
– Availability – Fatigue resistance
Unless you have a Sintech 20/G load frame in your kitchen, you’re unlikely to
notice the difference in tensile strength.
You may, however, notice the oxidation and corrosion resistance. If you use
foil mainly for storage, pristine foil is better for its corrosion resistance. If
you mostly cook at high temperatures with the foil, recycled wins with
oxidation and fatigue resistance.
And of course, you always notice the difference in your wallet. Recycled foil is
usually around twice the cost of pristine foil, despite costing around 90% less
It really just comes down to one issue: cost to you vs. cost to the environment
