PROBLEM TO BE SOLVED: To provide a high gloss food container lid composed of a rubber modified styrenic resin having high glooss, high impact strength, high rigidity and high surface hardness and especially used as yoghurt. SOLUTION: In a rubber modified styrenic resin containing a rubbery elastomer as dispersing particles, a resin phase is a polymer consisting of 30-70wt.% of a styrenic monomer (a) and 70-30wt.% of an acrylic ester monomer (b) and the average particle size of rubber particles of a dispersion phase is 0.3-2.0μm. A sheet obtained from the rubber modified styrenlc resin containing 5-15wt.% of the rubbery elastomer is thermoformed to obtain a food container. |
