Samples of PVC cling films were taken at importers, wholesalers and retail shops, and their overall migration to the alternative food simulant iso-octane was measured, after establishment of a correlation between overall migration to olive oil at 40 degrees C in 10 days and to iso-octane in 2 h. Results of the migration testing were compared with the recommended and/or actual use of the PVC film and the labelling discussed in relation to the relevant EEC directives on food contact plastics. The correct labelling of plasticized PVC film intended for use in retail packaging is important to avoid the risk of significant consumer intakes of the plasticizer di-(2-ethylhexyl) adipate (DEHA) after the film has been used in contact with fatty foodstuffs. Sixty percent of the films declared for use in contact with fatty foods showed too high overall migration compared with the current interpretation of legislation at the time of sampling. In most instances DEHA made up about 80% of the total amount of plastic constituents migrating to iso-octane. Taking into consideration a specific migration limit of 3 mg DEHA/dm2, 77% of the films used for fatty foodstuff analysed were not acceptable. The migration of DEHA to non-fatty foods defined as the food simulant water was at or below 0.1 mg/dm2 in all PVC-films.
在进口商、批发商和零售商店采集了聚氯乙烯保鲜膜样本，并在确定了聚氯乙烯保鲜膜在40摄氏度下10天内迁移至橄榄油中的总量与2小时内迁移至异辛烷中的总量之间的相关性之后，测定了其向替代食品模拟物异辛烷中的总迁移量。将迁移测试结果与聚氯乙烯保鲜膜的推荐和/或实际使用情况以及根据欧盟委员会关于食品接触塑料的相关指令所讨论的标签进行了比较。用于零售包装的增塑聚氯乙烯保鲜膜的正确标签标注对于避免在该保鲜膜与高脂肪食品接触使用后消费者大量摄入增塑剂己二酸二（2-乙基己基）酯（DEHA）的风险十分重要。与抽样时对法规的当前解释相比，宣称用于与高脂肪食品接触的保鲜膜中有60%显示出过高的总迁移量。在大多数情况下，DEHA占迁移至异辛烷中的塑料成分总量的约80%。考虑到DEHA的特定迁移限量为3毫克/平方分米，所分析的用于高脂肪食品的保鲜膜中有77%不合格。在所有聚氯乙烯保鲜膜中，DEHA向定义为食品模拟物水的低脂肪食品中的迁移量等于或低于0.1毫克/平方分米。
