Question:
When changing a child's diaper on shabbos, the adhesive tab of the diaper might become attached to the child's clothing. Is it a problem of borer to remove the attached diaper (the bad) from the clothing (the good)?
Answer:
It isn't borer because they are two separate items that are touching each other, and that is not considered a mixture, as it is clear that the two things are separate. This is the case with many korayah cases, such as separating tabs, pulling off the plastic seal on top of a container, etc. and it isn’t borer, in this instance it surely isn’t.
