食品包裝用合成樹脂製薄膜中可塑劑之調查

USE OF PLASTICIZERS IN FOOD PACKING PLASTIC FILMS IN TAIWAN

本調查之目的在於瞭解市售保鮮膜中可塑劑之使用類別及添加情形。檢體係於七十八年九月至七十九年五月間於台北市、台中市、高雄市共計價購30件不同廠牌及外包裝檢體，依材質之不同可分為聚氯乙烯類11件，聚偏二氯乙烯類6件，聚乙烯類12件，聚丁二烯類1件。針對己二酸二辛酯（DOA）、檸檬酸乙醯三丁酯（ATBC）、癸二酸二丁酯（DBS）及苯二甲酸二丁酯（DOP）等四種常用可塑劑以氣相層析法進行檢驗；其中聚乙烯及聚丁二烯類均未檢出上述四種可塑劑；聚氯乙烯類檢出DOA者6件（0.23～21.35 %），ATBC者1件（2.58%），DBS者1件（1.79 %），混合使用DBS與DOP者1件（分別為3.10及2.90%），另有2件檢體未檢出上列四種可塑劑；聚偏二氯乙烯類檢出混合使用DBS與ATBC者5件（分別為0.18～0.26%及2.31～2.99%），混合使用DBS、ATBC與DOA者1件（分別為0.20、2.45及0.16%）。

The intent of this report is to underst and the usage and type of plasticizers used by the plastic film industry being sold in Taiwan. Thirty plastic film products from various brand and packaging were sampled between September, 1989 through May, 1990. Among the collected samples, 11 products were made of polyvinyl chloride (PVC), 6 of polyvinylidenedichloride (PVDC), 12 of polyethylene (PE), and one of polybutadiene (BDR). The GC procedures were used to test for dioctyl adipate (DOA), acetyltributylcitrate (ATBC), di-butyl sebacate (DBS), and dioctyl phthalate (DOP). The results showed that 11 tested PVC, 6 contained with DOA (0.23-21.35%), 1 with ATBC (2.58%), 1 with DBS (1.79%) and 1 with a mixture of DBS & DOP (3.10% and 2.90%), while 2 products have found none of the 4 plasticizers. Of the 6 tested PVDC, 5 contained both DBS (0.18-0.26%) and ATBC (2.31-2.99%), 1 contained DBS (0.20%), ATBC (2.45%) and DOA (0.16%). None of the four tested plasticizers were found in the 13 PE and BDR plastic film products.
