A crystallized, thin-walled container, suitable for packaging foodstuffs which are subsequently heated, is obtained by thermoforming a sheet which has a crystallinity index of below 15% and an elongation of not less than 100% at room temperature and which has been obtained from a poly(arylene sulfide) which has as substantially linear structure, has not less than 70 wt% of a repeating unit <CHEM> and has a logarithmic viscosity number of 0.2 to 1.0 in a solution of l-chloronaphthalene (concentration of 0.4 g/dl at a temperature of 208 DEG C). |
