Mechanical Strength Evaluation of Functional Film Used in Smartphones

Introduction

Plastic film is formed into thin film using techniques such as extrusion and stretch molding of the polymer film. A wide variety of products having special characteristics, such as water retentivity, light reflectivity, and selective permeability for specific substances, can be found all around us as industrial products, construction materials, as well as everyday necessities. Recently, a wide range of multi-functional films have been developed which possess a variety of special characteristics designed to provide such functionality as enhanced protection and visibility in display screens for smartphones and LCD televisions. These multi-functional plastic films can also be designed to provide enhanced security, insulation, and light shielding for automotive and architectural glass products. This paper introduces an example of the strength evaluation of self-repair coating film used on the functional protective film that covers the LCD screens of such products as smartphones and tablets.
