Vacuum Bagging Film
Vacuum bagging films form the sealed envelope required to maintain vacuum pressure across the laminate throughout processing. Film selection is determined by cure temperature, part size and geometry, elongation requirements and bag configuration to support reliable sealing, conformity and process control.
Airtech
L100 Big Blue
General Purpose Bag Film
A cost-effective, multi-layer polyolefin vacuum bagging film for resin infusion and wet lay-up applications where cure temperatures do not exceed 121°C (250°F).
Key Features
- Super-wide film reduces seaming time on large parts
- Fewer seams lower the risk of vacuum leaks and scrap
- Flexible and easy to handle in typical workshop conditions
- Economical option for low-temperature vacuum bagging

Selecting the right bagging film
1. Process
Temperature
Select a film with a maximum service temperature comfortably above the expected cure or processing temperature.
2. Resin & Chemical
Compatibility
Confirm the film is compatible with the resin system, solvents and other processing materials being used.
3. Elongation and
Conformability
Complex moulds, deep draws and tight corners require a film with sufficient elongation to conform without bridging or excessive stress.
4. Film Width
and Format
Choose a width and fold format that minimises seams, reduces preparation time and provides enough material for pleats and movement under vacuum.
