Does EVOH Meet FDA and EU REACH Requirements?

In the global market for high-barrier packaging, Evoh (ethylene-vinyl alcohol copolymer) has earned a reputation for delivering outstanding protection against gas permeation. Its applications range from food, fresh produce, and ready-to-cook meals to medical devices, automotive fuel tank liners, and underfloor heating pipes.

Yet, when supplying to high-standard markets such as the United States and the European Union, performance alone is not enough. Products must also meet stringent regulatory standards — with U.S. FDA food-contact compliance and the EU REACH framework being two of the most critical benchmarks.

1.What Makes EVOH a Preferred Barrier Material

EVOH is a thermoplastic copolymer formed from ethylene and vinyl alcohol. In multilayer films like PA/EVOH/PE or PP/tie/EVOH/tie/PP, it serves as the barrier layer that significantly reduces the transfer of gases such as oxygen and carbon dioxide. This feature extends shelf life, preserves product quality, and safeguards flavor.

Under comparable thickness, EVOH polymer can achieve an oxygen transmission rate (OTR) of under 0.05 cc/m²·day, which far surpasses the barrier properties of PA or PE. It also offers strong sealing adaptability, mechanical durability, and stable processing behavior — making it well-suited for vacuum-sealed pouches, MAP (modified atmosphere packaging) films, sterilization packaging in healthcare, automotive fuel system components, and oxygen-protective piping.

2.EVOH and U.S. FDA Food-Contact Compliance

2.1 Regulatory Basis

In the U.S., plastics used in contact with food are regulated under 21 CFR Part 177, which covers “indirect food additives.” Section 177.1360 sets out the specific parameters for EVOH plastic, including the allowable ethylene-to-vinyl alcohol ratio, compatible food types, temperature resistance, and permitted additives.

If an EVOH formulation and its intended application fall within these criteria, it is considered compliant for lawful use in food-contact materials.

2.2 Industry Example

A major American frozen food company replaced its traditional PA/PE packaging with a PA/EVOH/PE co-extruded structure. The EVOH resin used was fully compliant with 21 CFR 177.1360 and passed both pasteurization and deep-freeze performance tests. The result: product shelf life improved by nearly one-third, and every export batch to North America cleared inspection without delay.

For modified EVOH — for instance, those containing extra comonomers or tailored additives — companies may opt for the FDA Food Contact Notification (FCN) route to secure approval. A case in point is Kuraray’s FCN 2115, which authorizes a specific EVOH formulation for designated uses. For U.S. market entry, it is essential to verify that the EVOH material either complies with 21 CFR 177.1360 or holds a valid FCN authorization.

3.EVOH under EU REACH Regulation

3.1 The Polymer Exemption

The EU’s REACH Regulation (EC 1907/2006) governs the registration, evaluation, authorization, and restriction of chemicals. Under current rules, polymers — including EVOH — are generally exempt from the registration requirement.

That said, the monomers and additives used to produce EVOH pellets must be registered, and the final material must comply with any restrictions and SVHC (Substances of Very High Concern) provisions.

3.2 Compliance Across Sectors

Food & Fresh Produce Packaging – European and U.S. importers often require documentation proving compliance with both 21 CFR 177.1360 and (EU) No 10/2011, backed by migration test reports from accredited laboratories.

Medical Device Packaging – One manufacturer integrated EVOH as a mid-layer barrier in sterile barrier systems, meeting oxygen barrier requirements and passing ISO 11607 and post-EO sterilization testing. As the packaging did not directly touch pharmaceuticals or tissues, approval was based mainly on food-contact standards, reducing the regulatory process significantly.

Automotive Fuel Systems – EVOH liners are highly effective in lowering fuel vapor permeation, meeting U.S. EPA and California CARB standards. Although these uses do not fall under FDA or (EU) No 10/2011 regulations, REACH substance restrictions must still be observed for EU market entry.

4.FAQ

Q1. Do I need an FDA “certificate” for EVOH?

No single “FDA certificate” exists. Compliance is shown by meeting the relevant provisions (e.g., 21 CFR 177.1360) or having an approved FCN. Suppliers typically provide a written declaration of compliance supported by test results.

Q2. If EVOH is buried in the structure and does not touch food, is food-contact compliance still required?

It depends on whether the layer functions as a complete barrier. If EVOH resin is fully isolated and meets functional barrier standards, full food-contact compliance may not be necessary — but migration testing is still advisable to avoid trade disputes.

Q3. Does the REACH polymer exemption mean EVOH requires no compliance checks?

Not entirely. While EVOH polymer itself is exempt from registration, its monomers, processing aids, and any SVHCs are still regulated. Overlooking these could block EU market access.

Verifying EVOH plastic compliance is not a one-step task. It involves choosing the right resin grade, designing the correct multilayer structure, and conducting thorough validation tests. For food-contact uses, each factor — from resin selection to processing temperature — must align with the rules in the target market.

Because regulatory frameworks are periodically updated — whether it’s the FDA’s food-contact notices, new SVHC entries under REACH, or revised technical standards — staying informed through official channels like the FDA and ECHA is essential for long-term compliance.
