Seafood, known for its unique flavor and nutritional value, has become a staple on dining tables around the world. However, traditional seafood packaging has long faced a significant challenge: materials chosen for their high barrier properties often lack the necessary toughness and can be punctured by shrimp spines or crab shells, leading to air leakage and spoilage. On the other hand, increasing the thickness of packaging materials to improve puncture resistance often compromises barrier efficiency and raises costs, making oxidation and spoilage unavoidable over time.

Ethylene-vinyl alcohol copolymer (EVOH), recognized as a top-tier barrier material, is now offering an innovative solution to this long-standing dilemma between maintaining freshness and structural integrity. This solution not only involves the use of advanced materials but also represents a strategic approach to mitigating puncture risks while preserving the freshness of seafood throughout the supply chain.

In industries such as ready-to-eat meals, sauces, snacks, and prepared meats, high-temperature water boiling is a critical process for extending shelf life and ensuring food safety. Packaging bags must withstand prolonged immersion in boiling water, ranging from 100°C to 121°C, and endure the harsh conditions of high heat, humidity, and fluctuating pressures.

In this process, EVOH (Ethylene-Vinyl Alcohol Copolymer), known for its excellent barrier properties, is widely used in the design of premium retort pouches. It either replaces or complements aluminum foil to offer transparent, high-barrier solutions. But what factors are most important in determining the boiling resistance of EVOH retort pouches?

In the world of high-performance packaging, EVOH (ethylene-vinyl alcohol copolymer) has become a key material for ensuring product freshness, safety, and extended shelf life. As a crucial element in barrier packaging, EVOH has evolved beyond a basic raw material to a technology that defines packaging quality.

However, when it comes to choosing between the two main EVOH-based packaging options—high-barrier co-extruded films and laminated films—many companies find it challenging to balance “superior performance,” “cost control,” and a “sustainable future.” So, how can companies make the right decision to achieve optimal packaging value?

In today’s increasingly competitive global marketplace, packaging has evolved beyond a mere container to become a critical enabler of product preservation, brand value, and supply chain efficiency. When faced with challenges such as insufficient shelf life, high transportation loss rates, or poor compatibility with wide-web high-speed packaging lines, traditional packaging films often fall short. The introduction of wide-web EVOH co-extruded film is designed to overcome these limitations, offering an integrated solution that combines exceptional barrier properties, superior mechanical performance, and production efficiency. This innovative material provides forward-thinking companies with a future-ready solution for packaging upgrades.

In flexible packaging production, printing issues with PP and PE films, such as ink shrinkage and poor adhesion, are common. These challenges are primarily caused by the low surface energy of these materials. On the other hand, EVOH films are often recognized for their excellent printability and high bonding strength. But what exactly makes Evoh Films more suitable for printing? And how does their surface energy compare to that of PP and PE films?

With the momentum of global plastic agreements and the rise of the circular economy, the concept of “designing for recycling” has moved from an innovative idea to a fundamental industry strategy. EVOH (Ethylene-Vinyl Alcohol Copolymer), one of the top three high-barrier materials worldwide, not only offers superior performance in freshness preservation, safety, and lightweight design but also presents significant potential for growth within recyclable packaging systems.

The global packaging landscape is entering a period of profound transformation. With environmental regulations tightening, consumer expectations evolving, and technology advancing rapidly, the industry is shifting toward a new phase defined by intelligence, sustainability, and globalization.

As a recognized trendsetter in the sector, SWOP 2025 – Shanghai World of Packaging will unveil its theme, “The Deep Packaging Industry Matrix,” offering a forward-looking vision for the industry’s development. The event will also shed light on the strategic direction and emerging opportunities for EVOH in the next stage of packaging innovation.

The global packaging industry is entering a transformative era driven by sustainability, intelligence, and circular innovation. As a leading indicator of this shift, swop – Shanghai World of Packaging will celebrate its 10th anniversary at the Shanghai New International Expo Centre (SNIEC) from November 25 to 27, 2025.

This year’s exhibition will continue to serve as a comprehensive sourcing platform covering the entire packaging value chain. It will bring together the latest technologies, materials, equipment, and design concepts, offering a panoramic view of where the global packaging industry is heading next.

As one of the world’s leading high-barrier materials, ethylene-vinyl alcohol copolymer (EVOH) has carved out a distinct market presence in China. While its primary use remains concentrated in the packaging sector, a range of untapped potential markets awaits breakthroughs in cost-efficiency. Understanding the distribution and dynamics of these sectors is essential for assessing the current state and future growth of the EVOH market in China.

As the world strives for greater energy efficiency and sustainability, the operational costs and long-term reliability of district heating systems have become key concerns. Issues like metal corrosion and heat loss within these systems are major contributors to declining energy efficiency and rising maintenance costs. To optimize heating networks, selecting high-performance insulation materials has become essential. Among the most effective solutions are composite insulation pipes with EVOH (ethylene-vinyl alcohol copolymer) oxygen barrier layers. Thanks to their exceptional oxygen-blocking properties, these pipes offer a reliable solution for heating projects worldwide.
