Vacuum bag films and bag tubes
The sealed envelope transfers atmospheric pressure to the laminate and contains the vacuum path during debulk, infusion or cure.
In simple terms
The sealed envelope transfers atmospheric pressure to the laminate and contains the vacuum path during debulk, infusion or cure.
Best for
Wet lay-up consolidation, infusion and prepreg oven/autoclave bagging.
Watch out for
Select temperature, elongation, puncture resistance and size for the complete cycle; bridging and leaks defeat the stack.
Typical applications
Single-sided tools, large panels, oven cure and autoclave work.
