摘要

The antistatic polypropylene membrane comprises a polypropylene (PP) board (31), which consists of an antistatic active substance (32) for the protection against static interferences and is equipped with a surface that is formed as dim surface (34). Markings leaving behind during detaching of tool is mounted during the use of PP board as base plate for pruning an optical material such as polarizing substance, and fibration and powder are formed during repeated detaching of the optical material. The surface of the optical product is diminished by pressing or scraping.

Markings leaving behind during detaching of tool is mounted during the use of PP board as base plate for pruning an optical material such as polarizing substance, and fibration and powder are formed during repeated detaching of the optical material. The surface of the optical product is diminished by pressing or scraping. The optical material consists of optical membrane, polarized substance, a brightness enhancement film or a retardation film.
