市售聚苯乙烯杯、盒與紙杯之溶出物含量調查

SURVEY ON SANITATION STATUS OF POLYSTYRENE CUPS BOXES AND PAPER CUPS

本調查研究旨在了解國產聚苯乙烯製杯、盒及紙杯之溶出物含量現況。檢體係於七十七年八月至七十八年三月間由全省六縣市抽購不發泡聚苯乙烯杯31件，發泡聚苯乙烯餐盒30件，發泡聚苯乙烯蛋糕盒30件及紙杯（內面塗敷有聚乙烯薄膜）30件。依據衛生署公告之食品器具、容器、包裝衛生標準、檢驗法及日本衛生試驗法注解予以檢驗。分析結果，不發泡聚苯乙烯杯均合乎我國現行聚苯乙烯製食品器具、容器、包裝衛生標准，其揮發性物質殘留量在346～4000ppm之間。發泡聚苯乙烯餐盒除溶出試驗均合於規定外，揮發性物質殘留量則有四件與標準不符，佔13.3%，分別為殘留苯乙烯單體超過1000ppm的有3件（1083ppm，1154ppm，2130ppm），乙苯超過1000ppm 1件（1207ppm），至於揮發性物質總量超過2000ppm者有2件（2346ppm，2704ppm）（見表一）。發泡聚苯乙烯蛋糕盒由市面糕餅店抽驗28件，另由製造工廠抽得2件；經檢驗顯示揮發性物質總量超過標準5000ppm者共有4件（9228ppm，6284ppm ，5720ppm，5895ppm）佔13.3%（見表二）；至於紙杯部份，因檢體內面塗敷有聚乙烯薄膜，故分為聚乙烯類及紙類兩部份予以檢驗，聚乙烯類依據衛生署公告之食品器具、容器、包裝衛生標準聚乙烯材質溶出試驗規定，30件檢體均合於標準；而紙類依據日本紙製器具衛生標準（見表三），進行檢測，結果亦均合於該規定。

In order to investigate the sanitation and safety of polystyrene cup, box and paper cup, total of 121 samples including 31 polystyrene cups, 30 foam polystyrene lunch boxes, 30 foam polystyrene cake boxs and 30 paper cups were examined. The results indicated that polystyrene cups were all meet the hyginenic standard of food utensils, containers and packages, four samples (13.3%) of foam polystyrene lunch box and four samples (13.3%) of foam polystyrene cake box failed to meet the standard of volatile marteial and styrene monomer. All paper cups tested were passed the requirment of Japanese hyginenic standard for paper-made container.
