The present disclosure provides a low gloss sheet and a matte product prepared therefrom. The low gloss sheet includes a substrate and a low gloss layer disposed thereon. The low gloss layer includespolyester and a matting agent. A weight percentage of the matting agent is 4 wt % to 10 wt % based on the total weight of the low gloss layer. The matting agent includes a plurality of first particlesand a plurality of second particles. An average particle diameter (d50) of the first particles and the second particles is 8 to 10 [mu]m and 3 to 6 [mu]m respectively. Oil absorption of the second particles is 30 to 100 ml/100 g. The matte product is prepared from the low gloss sheet by a forming technique. The low gloss sheet and molded product have low surface gloss, and multiple functions suchas a package material. 本发明提供一种低光泽板材及其成型品。低光泽板材包含基材以及形成于该基材上的低光泽层。低光泽层包含聚酯及消光剂。消光剂在低光泽层中的重量百分比为4至10wt％，并包含多个第一粒子及多个第二粒子。第一粒子的平均粒径d为8至10μm，而第二粒子的平均粒径d为3至6μm。第二粒子的吸油量为30至100ml/100g。本发明提供的成型品是由上述的低光泽板材经一成型制程而制得。本发明的低光泽板材及成型品具有较低的表
