Our flagship EVOH resin grades are engineered for superior barrier performance in flexible film structures — protecting freshness, extending shelf life, and meeting the most demanding packaging standards worldwide.
Ethylene Vinyl Alcohol (EVOH) copolymer is one of the most advanced thermoplastic barrier resins available today. Its unique molecular structure delivers exceptional resistance to oxygen, aromas, oils, and solvents — making it the material of choice for high-performance flexible film applications across food, pharmaceutical, agricultural, and industrial sectors.
EVOH resins offer oxygen transmission rates (OTR) as low as 0.01–0.05 cc·mm/(m²·day·atm) at 20°C/65% RH — outperforming nylon, PVDC, and most other barrier polymers in flexible multilayer film structures.
By adjusting the ethylene mole percentage (typically 24–48 mol%), EVOH grades can be precisely engineered to balance barrier performance, processability, moisture sensitivity, and flexibility — enabling customized solutions for diverse flexible film applications.
Modern EVOH formulations support recyclable and mono-material flexible film structures, aligning with global circular economy targets. EVOH enables brands to meet EU and international packaging sustainability directives without sacrificing performance.
Advanced EVOH grades from TPS maintain structural integrity under high-temperature processing conditions (up to 220°C+), ensuring consistent barrier properties in co-extrusion, blow molding, and lamination processes for flexible films.
EVOH flexible film layers provide an effective barrier against hydrocarbons, organic solvents, aromatic compounds, and flavor/aroma migration — critical for pharmaceutical blister films, chemical packaging, and specialty food packaging.
TPS EVOH resins are compatible with blown film co-extrusion, cast film extrusion, thermoforming, and stretch blow molding processes — offering flexible film manufacturers maximum production flexibility and equipment compatibility.
The global flexible film packaging market is undergoing rapid transformation. EVOH plastic raw material sits at the intersection of multiple powerful macro-trends reshaping how products are packaged, preserved, and delivered worldwide.
Global food waste reduction initiatives are pushing food manufacturers toward high-barrier flexible films incorporating EVOH layers. Modified Atmosphere Packaging (MAP) and vacuum packaging using EVOH-based multilayer films can extend product shelf life by 3–5× compared to conventional packaging — directly reducing supply chain losses and improving retailer margins.
The EU Packaging and Packaging Waste Regulation (PPWR) and similar legislation globally are mandating recyclability targets for flexible packaging by 2030. EVOH technology is evolving to support all-polyolefin recyclable flexible film structures, enabling brands to maintain barrier performance while achieving compliance with circular economy requirements.
The post-pandemic expansion of pharmaceutical manufacturing has dramatically increased demand for high-barrier blister films, pouch packaging, and medical device packaging. EVOH resins provide the moisture and oxygen barrier performance required for sensitive active pharmaceutical ingredients (APIs) and sterile medical products in flexible film formats.
China, India, and Southeast Asia are rapidly expanding flexible film production capacity, driven by growing middle-class consumption and food processing industrialization. TPS's R&D center in Chongqing positions us at the heart of this growth, enabling responsive supply, local technical support, and cost-competitive EVOH resin solutions for Asia-Pacific flexible film converters.
Smart agricultural films incorporating EVOH barrier layers are gaining traction for controlled-atmosphere storage, greenhouse applications, and silage preservation. Biodegradable and UV-resistant EVOH-based agricultural films represent one of the fastest-growing niche segments within the broader flexible film market.
Brand owners and retailers are demanding thinner, lighter flexible film structures without compromising barrier performance. EVOH's exceptional barrier efficiency per unit thickness enables significant material reduction — a critical driver as the industry targets lower carbon footprints and reduced packaging material consumption across the entire flexible film value chain.
From farm to pharmacy, EVOH plastic raw material enables high-performance flexible films across an expanding range of commercial and industrial applications. Explore the key sectors driving adoption.
Multilayer EVOH barrier films for vacuum skin packaging, shrink bags, and modified atmosphere trays — extending fresh meat and seafood shelf life while maintaining color and texture quality.
Breathable and barrier EVOH flexible films for fresh produce — precisely controlling O₂ and CO₂ transmission to optimize respiration rates and maximize shelf life for fresh fruits and vegetables.
High-barrier EVOH flexible films for pharmaceutical blister packaging and foil-free pouches — protecting moisture-sensitive tablets, capsules, and APIs from oxygen and humidity degradation.
UV-resistant and biodegradable EVOH agricultural films for silage preservation, greenhouse applications, and controlled-atmosphere storage — reducing crop losses and improving farm productivity.
Aroma and oxygen barrier EVOH films for cosmetic pouches, sachets, and laminate tubes — preserving fragrance integrity and active ingredient efficacy throughout product shelf life.
Solvent-resistant EVOH flexible film structures for industrial chemical packaging, fuel system components, and specialty industrial pouches requiring robust hydrocarbon barrier performance.
Ultra-clean EVOH barrier flexible films for retort pouches, squeeze packs, and stand-up pouches for baby food — meeting the strictest food safety and migration standards for infant nutrition products.
Emerging applications of EVOH flexible films in lithium battery pouch cells and sensitive electronics packaging — where extreme moisture and oxygen barrier properties are essential for product reliability and safety.
In multilayer flexible film structures, EVOH typically constitutes only 5–15% of total film thickness yet contributes over 80% of the total oxygen barrier performance. This extraordinary efficiency ratio makes EVOH plastic raw material the most cost-effective barrier solution available for flexible film manufacturers targeting premium shelf life and product protection outcomes.
