Our flagship EVOH-based high barrier film materials are engineered to meet the most demanding flexible packaging requirements — from food freshness preservation to pharmaceutical-grade protection.
EVOH (Ethylene Vinyl Alcohol) is a semi-crystalline thermoplastic polymer that exhibits outstanding gas barrier properties, particularly against oxygen, carbon dioxide, nitrogen, and organic vapors. When incorporated as a functional layer within flexible multilayer film structures, EVOH dramatically extends shelf life, preserves product integrity, and reduces the need for preservatives.
The ethylene content in EVOH resins typically ranges from 27 mol% to 48 mol%, with lower ethylene content providing superior barrier performance and higher ethylene content offering improved moisture resistance and processability. This tunability makes EVOH an ideal core layer in co-extruded flexible film structures used across food, pharmaceutical, agricultural, and industrial packaging markets worldwide.

The global EVOH resin market for flexible films has experienced robust growth, driven by escalating demand for extended shelf life packaging, stringent food safety regulations, and the shift away from rigid packaging toward lightweight, flexible alternatives. Valued at over USD 1.8 billion in 2023, the market is projected to exceed USD 3.2 billion by 2032 at a CAGR above 6.5%.
China, Japan, and South Korea are the dominant consumers of EVOH high barrier flexible films, accounting for over 42% of global demand. Rapid urbanization, rising middle-class disposable income, and evolving retail food formats are key growth drivers in the region.
Beyond food packaging, EVOH flexible films are gaining traction in automotive fuel system components, medical device packaging, agrochemical containers, and construction barrier membranes — diversifying the commercial base significantly.
Legislative pressure from the EU Packaging and Packaging Waste Regulation (PPWR) and similar global mandates is accelerating the development of recyclable mono-material flexible films incorporating ultra-thin EVOH barrier layers, reducing total material usage while maintaining performance.
EVOH high barrier films serve as the critical functional layer across a wide spectrum of flexible packaging applications. Below we explore the most commercially significant use cases driving industry adoption today.
Modified atmosphere packaging (MAP) films with EVOH barrier layers maintain optimal O₂/CO₂ ratios, extending fresh produce shelf life by 2–4× while reducing food waste across the cold chain.
EVOH barrier films protect agrochemicals, fertilizers, and seeds from moisture and oxygen degradation, ensuring product efficacy throughout extended storage and distribution cycles.
Ultra-low OTR (Oxygen Transmission Rate) EVOH flexible films are critical for blister packs and pouches housing moisture-sensitive APIs, ensuring drug stability and regulatory compliance throughout the product lifecycle.
Thermoformed and vacuum skin packaging films incorporating EVOH deliver the oxygen barrier performance required to prevent lipid oxidation and microbial growth, preserving color, texture, and flavor in fresh and processed meat products.
High-performance EVOH films for industrial applications including chemical containment pouches, solvent-resistant flexible liners, and specialty industrial barrier wraps requiring exceptional chemical resistance.
Retort-compatible EVOH multilayer flexible pouches maintain nutritional value and palatability of wet and dry pet food products, replacing rigid cans while offering significant weight and cost reductions.
Flexible laminate tubes and pouches with EVOH barrier layers prevent oxidation of active cosmetic ingredients, extending product efficacy and enabling premium packaging formats with excellent print quality.
Emerging applications in lithium-ion battery flexible pouch cells leverage EVOH's exceptional chemical barrier properties to prevent electrolyte permeation, a fast-growing segment driven by EV and energy storage demand.

The flexible film industry is undergoing a fundamental transformation driven by sustainability mandates, digital technologies, and evolving end-use requirements. EVOH high barrier films are at the center of this evolution.
Next-generation EVOH film architectures use ultra-thin barrier layers (as thin as 3–5 µm) within all-polyolefin structures, enabling full recyclability while maintaining commercial barrier performance — a breakthrough for circular economy compliance.
Research into bio-derived ethylene and vinyl acetate feedstocks is advancing, with partially bio-based EVOH resins already entering commercial trials, reducing the carbon footprint of high barrier flexible films significantly.
Machine learning algorithms are being deployed to optimize EVOH layer thickness, co-extrusion parameters, and tie-layer adhesive formulations, dramatically accelerating new flexible film product development cycles.
EVOH barrier layers are increasingly combined with oxygen scavenger technologies and NFC/RFID smart labels in flexible packaging formats, creating intelligent packaging systems that monitor freshness in real time.
New generation co-extrusion blown film and cast film lines operating at speeds exceeding 400 m/min are enabling cost-competitive production of 7–11 layer EVOH flexible film structures at commercial scale.
Modified EVOH grades with enhanced thermal stability are expanding the addressable market for flexible retort pouches, enabling sterilization at 121–135°C while maintaining structural integrity and barrier performance.
