Below is a comparison of the resistance of Tedlar bags, Kynar bags, Multi-Foil bags and Teflon (FEP) bags to Vapourised Hydrogen Peroxide (VHP), ethanol/alcohol, chlorine compounds, formaldehyde and UV/ozone.
| Material | VHP (Vapourised Hydrogen Peroxide) | Alcohols (Ethanol/IPA) | Chlorine Compounds (NaOCl, Cl₂) | Formaldehyde | UV / Ozon |
|---|---|---|---|---|---|
| Tedlar® (PVF) | Not resistant – strong oxidizer degrades film | Good resistance | Poor resistance – degradation/discoloration | Limited resistance | Not resistant |
| FEP (Teflon®) | Excellent resistance | Good resistance | Good resistance | Good resistance | Good resistance |
| Kynar® (PVDF) | Moderate resistance – better than PVF/PET, not as good as FEP | Good resistance | Fair resistance – may degrade over time | Good resistance | Limited resistance |
| Multi-Foil bags | Good resistance (aluminium barrier) | Good resistance | Good resistance | Good resistance | Good resistance, as long as alu barrier intact |
