求助300ml的塑料杯做欧洲全迁移的做法

食品接触材料

  • 一个300ml的塑料杯做欧洲全迁移
    1杯子的实际使用体积应该是已经的,我觉得应该直接加一定体积模拟也至杯口,按mg/Kg算全迁移值,量面积不必要
    2 如果量这个杯子的面积再根据1cm2:1ml的比例加食品模拟液,可能根据杯子面积算出来的体积太多溢出杯子或者太少而不能代表实际使用情况
    请大家讨论,谢谢

    标准没写的明确,见下,全迁移就写了盖子,垫片,塞子的表达方法。

    Article 17
    Expression of migration test results
    1. To check the compliance, the specific migration values shall
    be expressed in mg/kg applying the real surface to volume ratio
    in actual or foreseen use.
    2. By derogation from paragraph 1 for:
    (a) containers and other articles, containing or intended to con­
    tain, less than 500 millilitres or grams or more than 10 litres,
    (b) materials and articles for which, due to their form it is
    impracticable to estimate the relationship between the sur­
    face area of such materials or articles and the quantity of food
    in contact therewith,
    (c) sheets and films that are not yet in contact with food,
    (d) sheets and films containing less than 500 millilitres or grams
    or more than 10 litres,
    the value of migration shall be expressed in mg/kg applying a sur­
    face to volume ratio of 6 dm2
    per kg of food.
    This paragraph does not apply to plastic materials and articles
    intended to be brought into contact with or already in contact
    with food for infants and young children, as defined by Directives
    2006/141/EC and 2006/125/EC.

    3. By derogation from paragraph 1, for caps, gaskets, stoppers
    and similar sealing articles the specific migration value shall be
    expressed in:
    (a) mg/kg using the actual content of the container for which the
    closure is intended or in mg/dm2
    applying the total contact
    surface of sealing article and sealed container if the intended
    use of the article is known, while taking into account the pro­
    visions of paragraph 2;
    (b) mg/article if the intended use of the article is unknown.
    4. For caps, gaskets, stoppers and similar sealing articles the
    overall migration value shall be expressed in:
    (a) mg/dm2
    applying the total contact surface of sealing article
    and sealed container if the intended use of the article is
    known;
    (b) mg/article if the intended use of the article is unknown.

    如果单个物质风险评估没有给出更低的水平,根据GMP,物质释放少于10mg/dm2是可行的,这一限量应作为塑料材料惰性的通用限量

    最终结果应该是mg/dm2
    填充测试

    1楼和4楼不同的答案,纠结
    看了EU 10/2011,感觉里面也没说清楚

    充填测试,mg/dm2出具单位。

    专家能解释下吗? 谢谢
    如果量这个杯子的面积再根据1cm2:1ml的比例充填食品模拟液,可能根据杯子面积算出来的体积太多溢出杯子或者太少而不能代表实际使用情况

    容器类的用EN1186-9进行填充测试。按EU No 10/2011,单位出具mg/dm2。

    填充的 都需要填满
    再蒸发残渣就可以了
