Perfect, never again Tupperware!

I made this film rolls absolutely convinced in sizes 20x600 and 30x600 in my Vacuumierer Proficook PC VK 1015 in use, and am. The material is stable, food can be in freeze optional or even cook in sous-vide. Had as yet no single leaker, everything is safe salvaged.
The roles have over the finished bags has the advantage that you can tune the size individually to the freezing or cooking product, so you can easily and long pieces, such as spare ribs or venison with bone welding fact on the other side but wasted one does not so much material as you possibly just short cuts at the end.
Clear recommendation so from me!
