<p>PURPOSE: A self-adhesive protective film for protecting a light-guide plate is provided to facilitate the control of impurities by preventing the generation of fish eye and gel, to have excellent film-cuttability at cutting after packing in an automatic packing machine, and to facilitate attachment and detachment. CONSTITUTION: A self-adhesive protective film (10) for protecting a light-guide plate comprises an outer layer (11) which includes a polypropylene, a low density polyethylene, and a blocking preventer; a medium layer (12) which includes a low-density polyethylene or linear a low-density polyethylene; and an inner layer (13) including a metallocene ultralow density polyethylene and a metallocene linear low density polyethylene. The outer layer includes 10-80 wt% of the polypropylene, 10-80 wt% of the low density polyethylene, and 5-15 wt% of the blocking preventer. The mixing weight ratio of the metallocene ultralow density polyethylene and the metallocene linear low density polyethylene in the inner layer is 9:1-1:9.</p> |
