description PURPOSE: A contraction film and sheet resin composition for blocking UV ray is provided, which is not modified optically, discolored, or aged when it is radiated by UV ray for a long time. CONSTITUTION: The resin composition comprises 0.05-0.8 wt% of benzotriazole-based UV absorbing agent represented by the formula 1 as the first-state antioxidizing agent; 0.01-1.00 wt% of a hindered phenol-based UV stabilizing agent represented by the formula 2 as the second-state antioxidizing agent; optionally 0.01-2.0 wt% of an antistatic agent; and the balance of at least one resin selected from the group consisting of LDPE resin, HDPE resin, polypropylene resin, ethylene-propylene copolymer resin, ethylene-1-butene copolymer resin, ethylene-vinyl acetate resin and poly(vinyl chloride) resin. In the formula 1, X is H or halogen compound and R1 and R2 are a linear or branched alkyl group of C1-C8, and in the formula 2, R3 and R4 is a linear or branched alkyl group of C1-C8, and R5 is an ester group containing a linear or branched alkyl group of C10-C30.
