I’m terribly dyslexic (or something) and when I first read the title of this post I asked myself “Why would I want my pants heat sealed?”, of course the video clarified a lot. Just had to share, sorry
OOOO that’s how they do it. Always wondered! COOL STUFF!
I was down in Oaxaca, Mexico last year, and saw heat sealing done with a candle! The guy was quite good, and the seal kept my coffee fresh. Note – he poked the plastic bag with a pin to allow pressure equalization on the flight home.
