Liners for FIBCs & Octabins
Ünsa offers form-shaped liners made of LDPE, LLDPE, MDPE, HDPE, EVOH, PA, Conductive, Aluminum and Aluminum Conductive laminated films to protect the quality and the properties of the bulk material. Ünsa conductive form-shaped liners are made of food approved (white inside) co-ex conductive material. For aluminum laminated form-shaped liners, Ünsa uses various aluminum compounds depending on the specific needs of the customer. Form-shaped liners substantially improve the filling, discharging, handling and stability of the outer package.
Types of Standard Form-shaped Liners
Valve Sealing System
Welding a one-way degassing valve onto the liner enables gasses, steam, and vapors to escape, while preventing outside air from entering the liner.
Ünsa Delta Liners (Formstable Liners)
FIBCs with the square or rectangular shaped patented PE Delta Liner provide an effective utilization of space for storage and transport.
