Engineered for ultra-low oxygen transmission rates (OTR), exceptional aroma preservation, and compliance with strict EU/Irish food packaging recycling frameworks.
An in-depth look at how Ireland’s world-class agri-food exports, biopharma hub, and rigorous sustainability directives rely on premium EVOH barrier polymer chemistry.
Ireland boasts one of the most sophisticated agri-food export sectors globally, generating over €16 billion annually through premium dairy (Kerrygold, grass-fed butter, infant nutrition formulas), prime Irish beef and lamb, and Atlantic seafood. Because over 85% of Irish food production is exported to the UK, Mainland Europe, North America, and Asia, shelf-life extension without artificial preservatives is an absolute supply-chain imperative. Ethylene Vinyl Alcohol (EVOH) co-extruded barrier films (5-layer, 7-layer, 9-layer, and 11-layer structures) serve as the backbone for vacuum skin packaging (VSP), modified atmosphere packaging (MAP), and high-barrier bag-in-box systems that protect these sensitive food products throughout extensive maritime logistics routes.
Irish beef steaks, minced lamb, and block cheddar cheeses require packaging materials with ultra-low oxygen transmission rates (OTR < 0.5 cc/m²·day·atm) to prevent myoglobin oxidation, discolouration, and lipid rancidity. EVOH resins integrated into PE/EVOH/PE multi-layer barrier films preserve authentic bloom and flavor across cold-chain distribution networks.
Centred in Cork, Dublin, and Galway, Ireland hosts 9 of the world’s top 10 pharmaceutical companies. Injectable drugs, diagnostic reagents, and surgical instruments mandate hermetic moisture-and-oxygen barrier thermoformed webs. EVOH acts as an inert, sterilizable barrier layer, resisting pinholing and organic solvent permeation.
From Killybegs to Castletownbere, Irish seafood processors utilise thermoforming EVOH bottom webs and high-clarity peelable lidding films. These high-barrier films lock in natural moisture, prevent freezer burn, and retain delicate aromas under modified carbon dioxide/nitrogen gas mixtures.
Ireland’s extensive pastoral farming sector utilizes agricultural stretch films and fumigation barrier sheets. Incorporating EVOH barrier layers into agricultural silage films blocks oxygen ingress, optimizes anaerobic fermentation, and preserves winter cattle feed quality with minimized spoilage.
Under the European Union’s Packaging and Packaging Waste Regulation (PPWR) and Ireland’s National Waste Action Plan for a Circular Economy managed by Repak Ireland, all packaging placed on the market must be recyclable in practice and at scale by 2030. Traditional multi-material structures combining aluminium foil or PVDC are rapidly being phased out due to recycling stream contamination.
Our ultra-thin EVOH copolymer technology provides the perfect solution: by maintaining the EVOH barrier core thickness below 5 wt% of the total polyolefin film structure (e.g., all-PE or all-PP recycle-ready laminates), film extruders in Ireland achieve Class A recyclability ratings according to CEFLEX and RecyClass guidelines while retaining gas barrier performance equal to metallized substrates.
Selecting the right ethylene molar percentage (mol%) is essential for balancing processability, flex-crack resistance, thermoforming depth, and gas barrier efficacy.
