Our core EVOH resin product series is engineered for high-performance multilayer barrier applications across food, pharmaceutical, and industrial sectors.
Ethylene Vinyl Alcohol (EVOH) copolymer is a semicrystalline thermoplastic resin recognized globally as the gold standard for gas barrier performance in multilayer packaging and industrial structures. Its unique molecular architecture — alternating ethylene and vinyl alcohol units — grants it an exceptionally low oxygen transmission rate (OTR), making it indispensable in applications where product freshness, safety, and longevity are paramount.
In multilayer structures, EVOH is typically sandwiched between polyolefin layers (PE, PP) using tie-layer adhesives, creating a composite film or sheet that combines the mechanical flexibility of polyolefins with the unmatched gas barrier of EVOH. This synergy is the foundation of modern flexible food packaging, rigid containers, automotive fuel systems, and pharmaceutical blister packs.
The ethylene content in EVOH resin — typically ranging from 24 to 48 mol% — directly governs the balance between barrier performance and processability. Lower ethylene content delivers superior oxygen barrier but requires careful humidity management; higher ethylene content improves moisture resistance and melt processing ease, broadening its industrial applicability.
The EVOH resin market continues to expand as demand for high-performance barrier materials intensifies across multiple industries worldwide.
From sustainability mandates to next-generation food safety standards, several macro forces are accelerating the integration of EVOH into multilayer material systems globally.
Global regulatory pressure and consumer demand for sustainable packaging are driving the development of mono-material recyclable multilayer structures incorporating EVOH. Advanced compatibilization technologies now allow EVOH-containing multilayer films to be mechanically recycled without significant performance loss, aligning with EU Packaging Regulation 2025 targets and brand sustainability pledges.
With global food waste exceeding 1.3 billion tonnes annually, EVOH-based multilayer packaging has emerged as a critical technology for shelf-life extension. Modified atmosphere packaging (MAP) using EVOH barrier films can extend fresh produce shelf life by 3–5x, directly reducing food waste at retail and consumer levels — a key priority for major food brands and retailers.
The automotive industry's shift toward lightweight multi-layer plastic fuel tanks and emission control systems is a major growth driver for EVOH resins. EVOH layers in co-extruded HDPE fuel tanks provide the hydrocarbon permeation barrier required by increasingly stringent evaporative emission standards (CARB/Euro 6d), while enabling significant weight reduction versus metal alternatives.
Rising global pharmaceutical production and stricter drug stability requirements are fueling demand for EVOH-based blister packs, pouches, and IV bag multilayer films. EVOH's combination of oxygen and moisture barrier, chemical inertness, and regulatory compliance (FDA, EU 10/2011) makes it the preferred barrier layer for sensitive drug formulations and sterile medical devices.
Leading resin manufacturers are investing in bio-based ethylene feedstocks derived from sugarcane ethanol to produce bio-EVOH with identical performance to petroleum-based grades but a significantly reduced carbon footprint. This innovation positions EVOH as a future-proof barrier material compatible with the transition to a bio-circular economy.
Beyond traditional packaging, EVOH multilayer films are gaining traction in construction vapor barriers, agricultural greenhouse films, and geomembranes where long-term gas and chemical barrier performance is critical. The durability and UV-stabilized grades of EVOH are enabling new infrastructure applications with 20+ year service life requirements.
EVOH resin's versatility enables its integration into a wide spectrum of multilayer structures across diverse end-use sectors.
EVOH multilayer films are the backbone of modern MAP (Modified Atmosphere Packaging) for fresh produce, ready meals, and dairy. A typical structure of PA/EVOH/PE or PP/EVOH/PE provides an OTR below 1 cc/m²/day, maintaining optimal gas composition inside the pack to inhibit aerobic spoilage bacteria and mold growth, extending shelf life from days to weeks without preservatives.
Co-extruded multilayer fuel tanks with an EVOH barrier layer (typically HDPE/adhesive/EVOH/adhesive/HDPE or 6-layer variants) reduce hydrocarbon permeation by over 99% compared to monolayer HDPE, enabling compliance with CARB LEV III and Euro 6d emission standards. EVOH is also used in multilayer tubing for fuel lines, brake fluid reservoirs, and AdBlue (DEF) systems.
Premium cosmetic brands increasingly specify EVOH-containing multilayer tubes and bottles to prevent oxidative degradation of active ingredients (vitamins C & E, retinol, essential oils). The EVOH barrier layer preserves product efficacy and extends shelf life, supporting premium positioning and reducing product returns due to degradation.
Oxygen diffusion through plastic pipes in hydronic heating systems causes corrosion of metal components (boilers, pumps, radiators). EVOH-coated multilayer PEX and PE-RT pipes provide a certified oxygen barrier per DIN 4726, preventing oxygen ingress and extending system service life beyond 50 years — a standard specification in European building codes.
