Tacky Tape Vacuum Bag Sealing
Tacky Tape – Vacuum Bagging Sealant Tape
Tacky Tape is a high-performance sealant tape designed to create airtight seals in vacuum bagging and resin infusion applications. With its flexible, pressure-sensitive formulation, it provides reliable sealing around mould flanges, vacuum bags, fittings, and complex tooling shapes.
Engineered to maintain vacuum integrity throughout the curing process, tacky tape is an essential consumable for producing high-quality composite laminates.
Key Features
- Creates strong airtight seals for vacuum bagging
- Flexible and easy to apply around complex mould shapes
- Excellent tack and adhesion to tooling surfaces
- Maintains seal during cure cycles and elevated temperatures
- Easy removal with minimal residue
- Suitable for infusion, vacuum bagging, and prepreg applications
Typical Applications
- Vacuum bagging
- Resin infusion
- Prepreg processing
- Composite repairs
- Tooling and mould manufacture
- Oven and elevated temperature curing
Why Use Tacky Tape
Vacuum integrity is critical in composite manufacturing. Tacky tape helps prevent:
- Vacuum leaks
- Air contamination
- Poor laminate consolidation
- Resin-rich or dry areas
A reliable seal ensures consistent vacuum pressure and improved laminate quality throughout the process.

Ironbark Tip
For best sealing performance:
- Apply to clean, dry mould surfaces
- Avoid stretching the tape during application
- Firmly press vacuum bag film into the tape for a complete seal
- Double-seal critical areas around fittings and corners
