AIRDRAW 2 Vacuum Bagging Film

Overview

AIRDRAW 2 is an embossed vacuum bagging film designed to accelerate air evacuation in composite manufacturing processes. Featuring a “cracked ice” embossed structure, it creates continuous air channels that enable rapid air removal under vacuum, improving compaction efficiency and reducing the need for separate breather materials in many applications. The film is engineered for stability under varying environmental conditions and maintains its structure even in high humidity environments.
