Hadith on maintaining family ties

Q: It is reported in Sahih Muslim #2556 that "The severer would not enter Paradise". Ibn Umar said that Sufyan (explained it as): "One who severs the tie of kinship would not enter Paradise"

I would like to know 2 things from the above hadith:

1. Does the above hadith talk about blood relationship like your parents, siblings or does it include your relatives like cousins, uncles, etc.

2. Does the above mean a person will never enter paradise if he severs the tie of kinship?

Packing napaak clothes in one's luggage

Q: I was away on holiday and some of my clothes got napaak, once the clothes were dry I packed it in a plastic bag and then in my luggage. When I arrived home and unpacked my bag I noticed that most of my clothes were damp, the outside of the plastic bag didn't however seem to be wet (but I can't be 100% sure as it isn't easy to tell). I am not sure what happened at the airline that may have caused the clothes to get damp. My question is whether this makes my bags napaak and everything else that was in it
