Vacuum Bagging Film

Vacuum bagging film is a specialized material used in composite manufacturing processes, particularly in industries such as aerospace, automotive, and marine. It is used in conjunction with vacuum bagging techniques to create high-quality, strong, and lightweight composite parts. The film is typically made of polyethylene, nylon, or other thermoplastic materials that are airtight and durable.

Purpose:

• Vacuum Sealing: The film is used to create an airtight seal around the composite layup (a stack of composite materials like carbon fiber, fiberglass, or resin) to apply vacuum pressure.
• Pressure Application: Once the bag is sealed, a vacuum pump extracts air from the bag, which compresses the layers of material, improving their bonding and consolidation.
• Resin Infusion: In resin infusion processes, the vacuum bagging film helps in controlling the flow of resin and ensuring that it is evenly distributed throughout the layup.
