How Do EVOH High-Barrier Laminates Extend the Shelf Life of MAP Packaging?
EVOH high-barrier laminates laminate molded fiber trays in three structures — PE/EVOH, PP/EVOH, CPET/EVOH — with Excellent water/oil/alcohol barriers, covering the full span from chilled MAP to oven (CPET/EVOH) up to 180–220 °C.
Key Characteristics of EVOH High-Barrier Laminates
Excellent all three barriers
Water, oil and alcohol barriers are all "Excellent" — suitable for heavy-flavor and juicy foods.
Three structures to choose from
PE/EVOH for chilled MAP, PP/EVOH for microwave + barrier, CPET/EVOH for oven + barrier — pick by scenario.
Easy-peel and PET sealing
PE/PP/EVOH pair with easy-peel films; CPET/EVOH pairs with PET sealing film — covers mainstream sealing options.
Shelf-life extension
High oxygen barrier significantly extends fresh-food MAP shelf life — validate by testing.
Typical Parameters of the Three EVOH Laminate Structures
Data from the DNW film information sheet (2026); resistance values vary by supplier and test conditions — verify by testing.
| PE/EVOH high barrier | 0.045 – 0.10 mm × 810 – 1080 mm · Density 0.98 · Lamination 120 °C · Post-lamination resistance 120 – 130 °C · PE easy-peel film · Transparent |
|---|---|
| PP/EVOH high barrier | 0.045 – 0.10 mm × 810 – 1080 mm · Density 0.98 · Lamination 120 °C · Post-lamination resistance 120 – 150 °C · PP easy-peel film · Transparent |
| CPET/EVOH high-temp high-barrier | 0.08 – 0.20 mm × 780 – 1080 mm · Density 1.2 – 1.3 · Lamination 220 °C · Post-lamination resistance 180 – 220 °C · PET sealing film · Transparent |

EVOH Laminate FAQ
PE/EVOH or PP/EVOH — how to choose?
Pick by heating method: chilled MAP → PE/EVOH (120–130 °C resistance); microwave reheat → PP/EVOH (120–150 °C). Both rate Excellent on all three barriers.
Need oven + high barrier?
CPET/EVOH withstands 180–220 °C, giving oven + barrier in one. MOQ 3000 kg, with structures CPET35+EVOH45 to CPET50+EVOH150.
Does EVOH barrier drop in humid conditions?
EVOH loses barrier at high humidity — that's an inherent material characteristic. DNW laminate structures are designed to protect it; verify by testing.
