I can confirm it. I have a commercial vacuum packing machine, and a bag of rice sealed in it becomes a brick. You can't displace a grain of rice without damaging the vacuum. I doubt that a laptop inside this bag would survive it.

A commercial vacuum packing machine may be stronger than a normal home vacuum cleaner, which the article mentions. Fewer people have access to a commercial machine.

Yeah I was talking about the home vacuum cleaner method. The article mentions that first, but it does go on to mention vacuum packing machines too.

I could see vacuum packing machines possibly working for this.
