PROTECTIVE FILMS FOR TEXTURED SUBSTRATES

摘要

PURPOSE: A protective film for a textured substrate is provided to offer the controlled adhesive property in between a masking film and a textured surface to protect, under the various manufacturing condition. CONSTITUTION: A protective film for a textured substrate includes a surface contact layer(12) and a reinforcing layer(14). The surface contact layer contains the following: a mixture including a tetra-block styrene block copolymer elastomer with the adhesive force and a tri-block styrene block copolymer; a mixture of the tetra-block styrene block copolymer elastomer with the adhesive force and a tri-block styrene block copolymer including a di-block styrene block copolymer; a mixture of a tri-block styrene block copolymer with the adhesive force and the tri-block styrene block copolymer including the di-block styrene block copolymer; and a mixture of the tri-block styrene block copolymer including the di-block styrene block copolymer and low density polyethylene polymer.
