I'm new to the chamber vacuum sealing world. What is
the difference between 3, 4, and 5 mil bags? Why use each specific
thickness? - Dave N.
Great question, Dave! The thickness of the bag you select depends very
much on what is going into the bag and whether or not there is something sharp
that may puncture the bag. I have put together a table with samples for
thickness for you below:
It all has to do with the material being vacuum sealed and how likely will it
poke through the bag. The more likely it is to poke through, the heavier
and thicker your bag needs to be.
