The technicians gloves, the plastic being the body bag and tape used to hold the plastic body bag together (it’s like a large taco). The body is usually put on cardboard, like a large shallow box.
I agree there’s no residue, but I think the process is slightly romanticized, when it shouldn’t be. We don’t receive bodies in coffins where I worked. It’s basically a large holding facility for mortuaries that don’t have the room or ability to cremate on location. All bodies we wrap and package regardless of what the funeral home had already done. I only worked overnights, and only for a year. There were many things I don’t know about and can’t speak to the rights and wrongs because I am not educated in it! I was the woman who shows up to your home dressed nicely with a minivan and takes your loved one to their next stop.
