Our flagship plastic EVOH food packaging materials — engineered for superior oxygen barrier performance, thermal stability, and compliance with global food safety standards.
Understanding the science and commercial significance of EVOH barrier technology in modern food packaging.
Ethylene Vinyl Alcohol (EVOH) is a semi-crystalline thermoplastic copolymer renowned for its exceptional gas barrier properties — particularly against oxygen, carbon dioxide, and organic vapors. When incorporated as a core layer within multilayer plastic food packaging structures, EVOH acts as a molecular shield that dramatically slows the permeation of gases that cause food spoilage, oxidation, and flavor degradation.
Plastic EVOH food packaging typically consists of multilayer coextruded films or sheets where EVOH is sandwiched between polyolefin layers (such as PE or PP) and adhesive tie-layers. This architecture combines the mechanical strength and moisture resistance of polyolefins with the unmatched oxygen barrier of EVOH — creating packaging that keeps food fresh up to 5× longer than conventional single-layer plastics.
EVOH with 32–38 mol% ethylene content delivers the best balance of oxygen barrier performance and processability — the sweet spot for high-performance plastic food packaging applications.
The ethylene content of EVOH directly governs its barrier performance and processing characteristics. Lower ethylene content yields superior oxygen barrier but requires careful moisture management; higher ethylene content improves moisture resistance and melt processability. TPS engineers its EVOH grades across this spectrum to serve diverse plastic food packaging requirements — from fresh produce films to retort pouches and dairy containers.
The plastic EVOH food packaging market is experiencing robust growth driven by food safety regulations, consumer demand for longer shelf life, and the global shift toward high-performance barrier materials.
Regulatory bodies worldwide — including the FDA, EFSA, and China's NMPA — are tightening requirements for food contact materials. EVOH's proven compliance profile makes it the go-to barrier material for manufacturers seeking regulatory certainty in plastic food packaging.
The industry is actively developing mono-material and compatible-layer EVOH structures that improve recyclability without sacrificing barrier performance — addressing the EU's Single-Use Plastics Directive and extended producer responsibility (EPR) frameworks globally.
EVOH is increasingly combined with active packaging technologies — including oxygen scavengers, antimicrobial agents, and ethylene absorbers — to create intelligent plastic food packaging systems that actively extend shelf life and maintain food quality beyond passive barrier protection.
The explosive growth of online grocery and food delivery is driving demand for robust plastic EVOH food packaging that can withstand temperature fluctuations, mechanical stress, and extended transit times while maintaining food safety and appearance.
Demand for retortable EVOH packaging — capable of withstanding 121°C sterilization — is surging in the ready-meal, pet food, and institutional catering sectors, requiring thermally stable EVOH grades with specialized crystallinity profiles.
Geopolitical pressures and supply chain resilience concerns are accelerating the establishment of domestic EVOH production capacity in China and other emerging markets, reducing dependence on Japanese and European sources and creating competitive pricing dynamics.
Plastic EVOH food packaging serves a remarkably diverse range of industries and product categories — each with unique barrier, thermal, and regulatory demands.
EVOH multilayer films in vacuum skin packaging (VSP) and modified atmosphere packaging (MAP) for fresh meat dramatically reduce oxidative rancidity and microbial growth, extending retail shelf life from 5–7 days to 21–28 days. Thermoformed EVOH trays for deli meats and processed proteins are a major commercial application globally.
EVOH-barrier multilayer bottles and pouches for UHT milk, yogurt, liquid eggs, and sauces provide the oxygen barrier needed for aseptic processing and ambient-temperature distribution. The TPS EVOH 3801-DP grade is specifically engineered for dairy packaging with optimized moisture barrier and thermal performance.
Breathable EVOH films with controlled oxygen transmission rates enable optimal modified atmosphere conditions for fresh-cut salads, berries, and exotic fruits — balancing respiration needs with spoilage prevention. This segment is growing rapidly with the global expansion of fresh convenience foods.
EVOH blister packaging and bottles for tablets, capsules, and nutritional supplements provide critical moisture and oxygen barrier protection that preserves active ingredient potency and extends product shelf life — meeting stringent ICH stability testing requirements for pharmaceutical packaging.
EVOH barrier films for agricultural mulch, greenhouse covers, and agrochemical packaging provide chemical resistance and barrier properties that protect both the packaged product and the environment — a growing segment as precision agriculture adopts advanced plastic packaging solutions.
High-barrier EVOH retort pouches and trays for shelf-stable ready meals, baby food, and pet food represent one of the fastest-growing segments in plastic EVOH food packaging — combining convenience, long shelf life without refrigeration, and superior flavor and nutrient retention compared to canned alternatives.
