Tooling & Vacuum Bagging Processing

Vacuum Bagging Films
A vacuum bag provides pressure and vacuum, which always results in a better quality laminate. Pressure compacts the laminate, providing good consolidation and interlaminar bonds. Vacuum draws out the volatiles and trapped air, resulting in a low void content. Both help to improve resin flow. The latest generation vacuum bags for ambient cure compete on cost with polyethylene sheet, but offer superior performance.
