I've done my best to try to find out how he's resealing that ziplock baggie, but I can't figure it out. I read the comments and searched amazon for "Dretec" products but it doesn't seem it's available in the US.
I could think of many reasons to make custom sized ziploc baggies if it can be done reliably. I've tried with a household iron but I always had leaks and weak seams that would separate with pressure.
thanks,
BM
