EVA film

1. Introduction

The main characteristics of EVA film follows:

1) Excellent durability, such as weather resistance, high-temperature and high-humidity resistance, UV light resistance.

2) Excellent adhesion to glass, metal and plastics PET, TPT, Maintaining long term adhesion.

3) Excellent light transmittance and transparency.

4) Good manoeuvrability during lamination process.

5) Excellent PID resistance
