PURPOSE:To obtain a polyester resin composition improved in transparency, mechanical strengths, slip and stackability by mixing a polyethylene terephthalate resin with an ultrafine silica powder. CONSTITUTION:A polyethylene terephthalate resin is mixed with 0.01-1.0wt.% ultrafine silica powder of a mean primary particle diameter of 70nm or below and optionally a colorant, an antioxidant, a heat stabilizer, a filler, etc., to obtain a polyester resin composition. |
