It's called a 'metal ruler and soldering iron'.
You draw the iron tip quickly across the plastic baggy
(at a low angle) while holding the end closed with the metal ruler. You get a good seal
after a bit of practice to get the speed right.
Too fast you don't seal. Too slow and you melt through.
I do it all the time and it gives a nice hermetic seal.

You can also fold the open end over several times and tape fully (using packing
tape or 'vapor barrier' tape used in home construction.
