Title:
A multilayer film and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP6066357
Kind Code:
B2
Abstract:
Provided are a multi-layered film, a backsheet for a photovoltaic cell, a method of forming the same and a photovoltaic module. The multi-layered film may include a primer layer and a fluoropolymer coating layer formed by coating, and thus the fluoropolymer coating layer, which is a surface layer, may have excellent durability and weather resistance due to an inter-diffusion effect between materials in the respective layers, and a high interface adhesive strength with a substrate and the primer layer. In addition, in the preparation of the multi-layered film, a production cost may be reduced, productivity may be increased, and degradation in quality of a product caused by thermal transformation or heat shock may be prevented. The multi-layered film may be effectively used as a backsheet for various photovoltaic modules.
