▎ 摘　　要

NOVELTY - Adhesive film comprises three layers of ethylene vinyl acetate layer, polyolefin elastomer layer and ethylene vinyl acetate-polyolefin elastomer blending layer. USE - The adhesive film is useful in solar battery material. ADVANTAGE - The adhesive film: improves the volume resistivity, water vapor barrier performance, insulating performance and anti-attenuation performance under the wet thermal environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing adhesive film comprising mixing ethylene vinyl acetate layer, polyolefin elastomer layer and ethylene vinyl acetate-polyolefin elastomer blending layer uniformly, co-extruding, cooling and shaping the three-layer mixed materials.
