Application of EVOH Resin in 7-Layer Co-Extrusion Films: Structural Design for High-Barrier Packaging, Industry Solutions, and Trend Analysis
Amid growing concerns over global food spoilage rates exceeding 15% (FAO data), upgraded sterilization requirements in pharmaceutical packaging, and the surge in lightweighting demands for new energy batteries, 7-layer co-extrusion films—featuring EVOH material as the core barrier layer—are redefining the standards of high-value packaging.
By integrating "nano-barrier + circular design" technology, this innovation offers a comprehensive response to performance and sustainability needs. As a global core supplier of EVOH resin, we delve into the latest industry developments to analyze technical breakthroughs and cost-efficiency solutions across multiple applications.

Future Opportunities for EVOH Resin: Three Key Growth Drivers Revealed at the 2025 Shenzhen Chinaplas Expo
The 2025 Shenzhen International Plastics and Rubber Exhibition, themed “AI Manufacturing + Bio-Based Revolution,” gathered 4,500 global exhibitors and over 330,000 professional visitors. The event showcased cutting-edge technologies and innovations across the plastics and rubber industry.
Among the high-performance materials on display, EVOH (Ethylene-Vinyl Alcohol Copolymer) resin emerged as a central highlight, thanks to its outstanding barrier performance and sustainability potential.

EVOH High-Barrier Materials: Reshaping the Industry Standard for Fresh Sweet Corn Packaging
Driven by rising consumer demand for high-quality fresh food and the global push for carbon reduction, fresh sweet corn packaging urgently requires innovative materials that combine high barrier performance, mechanical strength, and environmental sustainability.
EVOH (ethylene-vinyl alcohol copolymer) resin, with its outstanding oxygen transmission rate (OTR) as low as 0.1 cm³/m²·day·atm, is transforming corn packaging from passive preservation to active freshness maintenance through multilayer co-extrusion and modified atmosphere packaging (MAP) technologies. It has become a key engine of technological advancement in the industry.

Application Analysis of PA/EVOH/PE Multilayer Co-Extrusion Films
With the increasing global demand for barrier performance, safety, and sustainability in the food packaging industry, multilayer co-extrusion technology has become the core process for producing high-barrier films.
Among these, the PA (Polyamide) / EVOH (Ethylene Vinyl Alcohol Copolymer) / PE (Polyethylene) three-layer composite structure stands out for its exceptional synergy, dominating applications such as fresh meat packaging, ready-to-eat meals, and liquid dairy products.

Modified Atmosphere Packaging (MAP) Film Technology: Driving the Development of EVOH High-Barrier Food Packaging
As the global food packaging industry advances toward greater safety and sustainability, high-barrier packaging materials are undergoing unprecedented technological upgrades. Among these, Modified Atmosphere Packaging (MAP) film technology has made significant breakthroughs in structural design, material innovation, and food preservation processes.

Nylon +EVOH Co-Extruded Film: The All-Rounder in High-Barrier Packaging
In sectors such as food preservation, industrial packaging, and agricultural fermentation, packaging performance directly impacts product quality and cost. In recent years, nylon co-extruded films have emerged as a market favorite due to their multilayer composite structure, outstanding barrier properties, and versatile process adaptability.

From 7-Layer to 9-Layer EVOH Co-Extruded Films: The Premium Choice for High-End Packaging
As the global packaging industry accelerates its shift toward high-performance and sustainable solutions, EVOH material (ethylene-vinyl alcohol copolymer) multilayer co-extruded films are experiencing rapid growth in applications across food, pharmaceutical, and electronic packaging. These films are evolving from being considered a "high-performance option" to becoming an essential material in advanced packaging systems.

Opportunities for EVOH in the New Energy Vehicle (NEV) Sector
As the global new energy vehicle (NEV) industry continues to grow rapidly, EVOH (ethylene-vinyl alcohol copolymer) resin—renowned for its outstanding barrier properties, excellent dielectric characteristics, and environmental stability—is emerging as a critical component in advanced material systems for NEVs.

Impact of the US tariff policy on China- EVOH resin export business
Recently, the U.S. government's policy of imposing additional tariffs on Chinese imports has triggered significant shifts in global trade dynamics, directly affecting the plastic packaging industry—including EVOH (ethylene-vinyl alcohol copolymer) resins.
As a high-performance barrier material, EVOH polymer is widely used in food and pharmaceutical packaging. While global demand for EVOH plastic remains relatively stable, the U.S. tariff policy may still impact China’s export trade through both direct and indirect channels.
