Would this work to put under a sheet in a crib to keep babies bed warm?

They do work for an outside feral cat I am caring for. I put a sheet under a blanket to keep cat warm and it is warm. but cat was scared of the the crunching sound. I used one blanket and it keeps you warm. I believe putting one under baby blanket would help keep baby warm.

Are these puncture proof? Do they tear easily?

Compared to similar mylar blankets, they are sturdier and longer lasting. However, they will puncture, and they will tear. They are not like regular blankets, not like tarps or similar things. They are not made for rough handling, but for heat and protection while sleeping or in emergency situations.

How many microns in thickness?

don't know the micron. it does have a mesh-like structure, almost like ripstop. it is light and durable. thicker than what foil balloons are made of but thinner and more flexible than tinfoil. I have worn it in -30 F and its worked wonders.

Odd question. can these block radio interference? i have a neighbor who plays with a cb radio and i pick up his transmissions and it's annoying.

Hell no . You need copper . Copper blocks all radio frequency
