Collaboration between EVA Photovoltaic Film Industry and Belt and Road Countries Promotes Renewable Energy Development

As a crucial component of photovoltaic modules, EVA (Ethylene Vinyl Acetate) photovoltaic film plays an essential role in advancing renewable energy development and addressing climate change. In recent years, the collaboration between the EVA photovoltaic film industry and Belt and Road countries has become increasingly close, providing new opportunities for the development of local renewable energy industries.

The Belt and Road Initiative aims to strengthen regional connectivity, enhance economic cooperation, promote sustainable development, and facilitate the application and popularization of clean energy. Against this backdrop, the collaboration between the EVA photovoltaic film industry and Belt and Road countries has become a focal point.

Firstly, Belt and Road countries possess abundant solar resources, making them suitable for solar power generation. Moreover, these countries are facing a growing demand for electricity. As EVA photovoltaic film is a critical material for solar panels, its demand has also increased accordingly. The collaboration between Belt and Road countries and EVA photovoltaic film suppliers can meet the increasing development needs in the renewable energy sector.

Secondly, the Belt and Road Initiative facilitates the exchange of technologies and promotes cooperation between countries. The production of EVA photovoltaic film requires advanced technology and equipment. However, some Belt and Road countries are still in the early stages of developing their photovoltaic industries, and their technological capabilities may be limited. Through collaboration with technologically advanced EVA photovoltaic film suppliers, these countries can learn from advanced manufacturing techniques and management experiences, enhancing their local industries' competitiveness.

Furthermore, the Belt and Road Initiative presents new investment opportunities for the EVA photovoltaic film industry. Belt and Road countries require infrastructure construction and energy development. This provides more opportunities for project construction and investment in the EVA photovoltaic film industry. Through cross-border investments and collaboration, EVA photovoltaic film suppliers can introduce advanced production equipment and technologies to Belt and Road countries, driving the development of renewable energy together.

In conclusion, the collaboration between the EVA photovoltaic film industry and Belt and Road countries is closely interconnected and mutually beneficial. The Belt and Road Initiative supports the development of the photovoltaic industry by providing market demand, promoting technology exchange, and offering investment opportunities. This collaboration provides Belt and Road countries with essential materials and technological support necessary for renewable energy development while also driving the globalization of the EVA photovoltaic film industry.

EVA vs. POE vs. EPE Solar Encapsulation Films: Market Trends & How to Choose the Right Extrusion Line

Executive Summary for PV Encapsulation Line Buyers

As N-type TOPCon and HJT solar technologies become mainstream, selecting the right photovoltaic (PV) encapsulation material—and the corresponding extrusion equipment—is critical for solar module performance. While EVA remains the low-cost standard and POE offers superior PID and water barrier properties, EPE co-extruded film (EVA/POE/EVA) has emerged as the most cost-effective solution for dual-glass and bifacial modules.

As a leading plastic extrusion machinery manufacturer, GWELL Machinery provides high-efficiency, multi-layer co-extrusion production lines designed to overcome processing challenges like POE additive slip and layer thickness variation in EPE film manufacturing.

1. EVA Film: Pros, Cons, and Machinery Requirements

Ethylene-Vinyl Acetate (EVA) film has long dominated the PV module encapsulation market due to its mature processing technology and cost-effectiveness.

• Advantages:

  • Cost-Efficient & Abundant Raw Materials: Lower material cost with stable domestic supply chains.

  • High Light Transmittance: Maximizes solar cell light absorption.

  • Strong Adhesion & Fast Cross-Linking: Excellent bonding strength to glass and backsheets, allowing rapid lamination cycles.

• Disadvantages:

  • Hydrolysis & Acetic Acid Generation: Degrades under high heat and moisture, producing acetic acid that corrodes solar cell ribbons.

  • Yellowing Risk: Prone to discoloration under long-term UV and thermal stress, reducing long-term efficiency.

• GWELL Machine Capability: EVA film production requires precise temperature control to prevent premature cross-linking inside the extruder. GWELL EVA Single/Multi-layer Extrusion Lines utilize specialized low-shear screws and high-precision temperature control systems, ensuring high output speed (up to 30m/min) while maintaining thermal stability.

2. POE Film: Pros, Cons, and Processing Challenges

Polyolefin Elastomer (POE) film is essential for high-efficiency modules (such as PERC dual-glass, N-type TOPCon, and heterojunction cells) due to its zero-water-absorption characteristic.

• Advantages:

  • Superior PID & Water Vapor Resistance: Highest electrical resistivity and lowest water vapor transmission rate (WVTR).

  • Zero Acetic Acid Corrosion: Chemical stability prevents cell contact degradation.

  • Anti-Yellowing & Thermal Aging Resistance: Ideal for offshore, floating, and harsh desert environments.

• Disadvantages:

  • High Material & Processing Cost: POE resins are significantly more expensive and heavily reliant on imports.

  • Extrusion & Lamination Difficulties: Non-polar POE resins cause cross-linking additives to migrate to the surface, leading to roller slipping, air bubbles, and lower lamination yield.

• GWELL Machine Capability: To solve the POE slip and additive separation issue, GWELL POE Extrusion Lines feature specialized screw geometry designed for low-temperature mixing, high-torque drive units, and textured embossing rollers that enhance surface friction and gas bubble release during lamination.

3. EPE Co-Extruded Film: The Ultimate Market Choice

EPE (EVA/POE/EVA) film is a 3-layer co-extruded structure that combines the best of both worlds: the high adhesion and fast lamination of outer EVA layers with the high moisture barrier and PID resistance of the inner POE core.

Key Advantages of EPE Film:

1. Balanced Cost-Performance Ratio: Reduces POE resin usage by up to 50% compared to pure POE film while retaining 90%+ of its barrier performance.

2. Eliminates Roller Slip: The outer EVA layers provide excellent surface grip, eliminating the processing instability associated with pure POE lines.

3. Superior Delamination Resistance: Multi-layer co-extrusion technology prevents inter-layer peeling during module lifespan.

4. GWELL EPE Solar Film Production Line Solutions

For PV film manufacturers, transitioning to EPE production requires advanced multi-layer co-extrusion machinery capable of precise layer ratio control. GWELL Machinery offers cutting-edge 3-Layer (ABA / ABC) Solar Encapsulation Film Extrusion Lines engineered for high-volume manufacturing.

GWELL Equipment Highlights:

• Multi-Extruder Co-Extrusion Architecture: Independent extrusion systems for EVA and POE layers allow precise regulation of the inner core layer thickness ratio (typically 1:2:1 or 1:1:1).

• Automatic Thickness Control (X-Ray Gauge): In-line closed-loop thickness measurement guarantees uniform film weight across widths up to 2,800 mm.

• Anti-Slip & Tension Management: Custom embossing chill rollers and multi-stage automatic winders prevent film stretching, sticking, and static buildup.

• Flexibility (EVA/POE/EPE All-in-One): GWELL lines are designed with high versatility, allowing manufacturers to switch between pure EVA, pure POE, and 3-layer EPE films on a single line with minimal downtime.

5. Market Outlook: Why Upgrade Your Production Capacity Now?

Market data indicates that the combined market share of POE and EPE films in China rose significantly to over 35%, with projections reaching over 50% market adoption. Driven by the rapid expansion of N-type solar cells, EPE is rapidly replacing pure EVA in dual-glass and bifacial module applications.

Investing in a high-flexibility co-extrusion line allows film manufacturers to capitalize on the lower production costs of EVA today while being fully prepared for the booming EPE demand tomorrow.
