发明名称 Verfahren zur Herstellung eines Lebensmittelbehälters
摘要 <p>A process for producing a thermoplastic polyester resin foam comprising melting a thermoplastic polyester resin, mixing the molten resin with a blowing agent and extruding the mixture into a low-pressure zone to carry out expansion molding, characterized in that a compound having two or more acid anhydride groups per molecule, optionally together with a compound of a metal of Group I, II or III elements of the Periodic Table is added to the thermoplastic polyester resin. There is also disclosed a process for producing a thermoplastic polyester resin foam comprising cooling a high-temperature foam immediately after expansion and then re-heating the foam. Further, a thermoplastic polyester resin foam sheet and a food container prepared from the foam sheet are also disclosed.</p>
