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!!
