Glass Laminate Using Textured Adhesive

摘要

A method for laminating glass, a laminate assembly, and an adhesive-coated plastic material used in a laminate assembly. Specifically an adhesive, once applied to a plastic layer is grooved or textured to allow formerly trapped air to escape from between layers of a laminate assembly during a laminate process. This can allow for the adhesive layer to be thinner, while still providing for a final product that is relatively air bubble-free and optically pleasing or substantially free of optical defects caused by waviness of the plastic layer between two PVB sheets and/or wrinkles of the plastic sheet.

1. An adhesive-coated plastic material used for forming laminated glass, the material comprising:
a flexible plastic film having two opposing sides; and a first layer of adhesive applied to at least one of said two opposing sides, said first layer of adhesive having a thickness in a range of 10 to 50 microns and further having a plurality of grooves, the grooves having respective widths in a range of 20 to 100 microns and respective depths in a range of about 10 to 50% of the thickness of the first layer of adhesive.
