Ethylene-Vinyl Alcohol (EVOH) copolymer resin is a semi-crystalline thermoplastic polymer produced by the saponification of ethylene-vinyl acetate copolymers. Available in granule form for easy processing, EVOH is widely recognized as the most effective gas barrier material used in multilayer food packaging structures today.
The ethylene content in EVOH granules typically ranges from 27 to 48 mol%, directly influencing the balance between barrier performance and processability. Lower ethylene content delivers superior oxygen barrier properties, while higher ethylene content improves moisture resistance and melt processing characteristics — making grade selection critical for specific food packaging applications.
As a core layer in coextruded multilayer films, EVOH granules provide an exceptional barrier against oxygen, carbon dioxide, nitrogen, and a wide range of organic solvents and aromas. This makes EVOH plastic resin indispensable for extending the shelf life of perishable foods, reducing food waste, and maintaining product freshness across global supply chains.
EVOH delivers the highest oxygen barrier performance among commercially available thermoplastics, preventing oxidative degradation of food products and dramatically extending shelf life — even at very thin film gauges.
High-grade EVOH resins such as TPS EVOH 3201-CP maintain structural integrity and barrier performance under demanding thermal processing conditions including retort sterilization, hot-fill, and pasteurization.
Modern EVOH formulations support sustainability goals by enabling thinner overall packaging structures, reducing total plastic usage. EVOH-based packaging is compatible with advanced recycling streams and contributes to circular economy objectives.
EVOH granules are designed for seamless integration into coextruded multilayer film structures with PE, PP, PA, and tie-layer resins, enabling cost-effective high-barrier packaging without sacrificing mechanical properties.
EVOH effectively blocks the permeation of organic solvents, oils, and flavor/aroma compounds, preserving the sensory quality of packaged foods and preventing off-flavors caused by packaging-food interaction.
TPS EVOH resins comply with major international food contact regulations including FDA (USA), EU 10/2011, and GB standards (China), ensuring consumer safety and facilitating global market access for food manufacturers.
From fresh produce to processed meats, from pharmaceutical packaging to agricultural films — EVOH granules enable high-performance barrier solutions across a wide spectrum of industries.
Vacuum skin packaging and modified atmosphere packaging (MAP) for fresh, chilled, and frozen meat products. EVOH barrier layers prevent oxidation, maintain color, and inhibit microbial growth.
Breathable and barrier films for fresh produce. EVOH enables precise gas composition control inside MAP packages, dramatically slowing respiration rates and extending freshness.
Blister packs, sterile pouches, and medical device packaging requiring ultra-low OTR. EVOH ensures drug stability, sterility maintenance, and compliance with stringent regulatory requirements.
Multi-layer agricultural films incorporating EVOH for controlled-release fertilizer packaging, pesticide containers, and greenhouse film applications requiring chemical resistance and durability.
Multilayer squeeze bottles, tubes, and pouches for cosmetics and personal care products requiring aroma retention, chemical resistance, and premium shelf appeal.
Aseptic cartons, pouches, and cups for dairy products, juices, and liquid foods. EVOH barrier layers prevent oxygen ingress and flavor scalping throughout extended ambient shelf life.
Multi-layer fuel tanks and industrial chemical containers utilizing EVOH's exceptional solvent barrier properties to meet stringent emission regulations and safety standards.
High-barrier pouches and containers for baby food, infant formula, and nutritional supplements where maximum oxygen protection and food safety compliance are non-negotiable requirements.
The global EVOH market is undergoing rapid transformation driven by evolving consumer expectations, regulatory pressure, and technological innovation in packaging science.
Global food supply chain complexity and the growth of e-commerce grocery are driving unprecedented demand for packaging solutions that extend shelf life without preservatives. EVOH-based multilayer structures are the material of choice for brands targeting 12–24+ month ambient shelf life for processed foods, sauces, and ready meals.
Regulatory frameworks in the EU, USA, and Asia are mandating recyclable packaging. Next-generation EVOH formulations are being developed for mono-material recyclable structures and are increasingly compatible with polyolefin recycling streams — balancing barrier performance with end-of-life sustainability.
Asia-Pacific represents the fastest-growing EVOH market, driven by rapid urbanization, rising middle-class consumption, and the modernization of food retail infrastructure in China, Southeast Asia, and India. Demand for high-barrier flexible packaging in these markets is growing at over 8% annually.
Advances in multilayer coextrusion technology are enabling thinner, more cost-effective EVOH barrier layers — as thin as 3–5 microns — without compromising performance. This reduces resin consumption and total packaging cost while maintaining excellent barrier properties.
Stricter global pharmaceutical regulations and the rapid growth of biologics and sensitive drug formulations are expanding EVOH demand beyond food into pharmaceutical blister packaging, IV bags, and sterile medical device pouches requiring ultra-high barrier performance.
EVOH is increasingly being combined with active packaging technologies such as oxygen scavengers, antimicrobial agents, and moisture regulators to create intelligent packaging systems that actively protect food quality — representing the next frontier of high-barrier packaging innovation.

In the Chinese mainland, TPS has established a dedicated R&D center in Chongqing City, focused on the research and development of high-tech materials.
