做全迁时，算面积到底是算一面还是两面，侧面要不要算?

厚度超过0.5mm时需计算两面
厚度超过2mm时需考虑将侧面计入面积

是不是出自这段话：
However, the experimentation can be avoided in the case of materials with a thickness greater than 0,5 mm
because it is conventionally agreed, except for plasticized polymers and multi-layer materials where the food
contact surfaces are different, that for these materials the calculation shall take into account the total surface
exposed.
可plasticized polymers and multi-layer materials 除外呀！！

plasticized polymers and multi-layer materials where the food
contact surfaces are different

读句子留意前后文。 不要漏掉这个定语where the food
contact surfaces are different。

确实，最后这一句最重要了

应助达人

如果双面都浸泡了，就算两面的。

感谢！！！

是的
