<p>PROBLEM TO BE SOLVED: To obtain a foamed sheet of a synthetic resin capable of improving deep-drawing property and the surface uniformity of a formed container. SOLUTION: This container is formed by using a synthetic resin foamed sheet constituted of a rubber component and a styrene-based resin and having at least a property of following (1) and (2). (1) The sheet has >=10% the surface gloss and (2) the rubber component has 0.5-5μm an average particle diameter. The synthetic resin foamed sheet may further have at least a property among following properties (3) to (7). (3) The glass transition point of a matrix phase in the styrene-based resin is 90-105 deg.C, (4) the content of the rubber component is 1-20 wt.%, (5) the foamed ratio is 1.1-3 times, (6) the average air cell membrane number per unit thickness is 1-50 pieces/mm, and (7) the thickness of the sheet is 0.3-2 mm.</p> |
