Product Improvement

CDF has created a customer benefit by modifying the IBC form-fit liner to include holes in the perforated flaps. The CDF engineering team strategically added holes to the perforated flaps of the IBC form-fit liner to help hold the liner in place during filling; by keeping the liner squared, these flaps make fills easier. Once the IBC form-fit liner is filled, the flaps can be detached and used with a winder for dispensing. CDF was the first flexible packaging manufacturer to add holes to the perforated flaps to a number of customized applications. This feature is now part of all of CDF’s stock IBC form-fit liners.

Formfit (cube-shaped) liners are manufactured to form fit the internal shape of your intermediate bulk container. Form-fit IBC liners provide high performance in critical applications, such as top-fill applications using a bridge or automated filler; containers with no access doors for placing a liner at the bottom; high speed fills and viscous products that would get caught in the folds of pillow-shaped liners.
