MULTILAYERED FILM AND METHOD FOR MANUFACTURING SAME

Title:

MULTILAYERED FILM AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2013/119069

Kind Code:

A1

Abstract:

The present invention provides a multilayered film, a method for manufacturing same, and a photovoltaic module. According to the multilayered film of the present invention, a barrier film having superior moisture barrier properties may be coated with fluoropolymer by using a primary layer including a silane-modified acrylic copolymer as a medium. Also, the multilayered film may secure interface adhesion in order to provide superior durability and weatherproofing and have superior interface adhesion with respect to a barrier film. In addition, when the multilayered film is manufactured, manufacturing costs may be reduced, productivity may be improved, and deterioration of quality due to thermal deformation or thermal shock may be prevented. Thus, the multilayered film may be, for example, effectively used for back surface sheets of various photovoltaic modules.
