Seal bags

I saw this on YouTube and its really amazing

I think it would be a nice feeling to be sealed in a strong bag and to know, you never can come out. 
(Unless somebody else will do it from the outside )

Do you know, if there is any possibility to test something like that?
Or to get some bags that are very similar strong to that ones?
Would like to play with them a little bit
