EPE film • EPE film • The rapid growth of the solar (photovoltaic, PV) industry is driving demand for advanced packaging materials for solar modules. This has led to the development of new materials, notably EPE film. • EPE film is a transparent, co-extruded multi-layer film specifically designed for solar panel encapsulation. It combines the benefits of two common polymers EVA and POE. This structure offers a balance of high adhesion, excellent barrier properties, strong weather resistance, and cost-effectiveness. • To support the widespread use of EPE film, a new product standard, TSHPTA 082-2024: "Co-extruded EPE film for photovoltaic module encapsulation," has been officially implemented. • Labthink Instruments
Labthink • A key contributor • This standard was developed by a team of experts from various fields, including new energy, new materials, testing instrument development, and research institutions. • Labthink, a company specializing in testing instruments, was a key contributor, sharing its expertise in material barrier and mechanical performance testing.

New Requirement for Mechanical Properties • Encapsulant films provide structural support within solar modules. The new EPE standard has higher requirements for elongation at break. • Peel strength is vital for module stability. The EPE standard not only increases the overall peel strength requirements but also adds new specific tests for peel strength between the film and the backsheet • 01 • 02
