Description

Dahlar® Release Bag 125 is an economical film designed for both vacuum bagging and release applications. It can be used for cures up to 140°C (285°F) and will release from most resins associated with aerospace, marine, and recreational products. This formulation has improved tear resistance and elongation over products previously offered as low temperature, multiple process films.

Dahlar® Release Bag 125 (25 µm or 0.001 inch) is the ideal release film for polyester or vinyl ester resins as well as epoxies and phenolics. See the release film section. It is also offered with our embossed patterns making it a breather, release film and vacuum bag all-in-one.

Benefits

• Reduce inventory cost with economical single choice film option for use as bag or release film.
• Tough, strong, and good elongation make bagging much easier than with other low cost products.
• Embossed version makes compaction and debulking faster and cheaper.
