Form-Fit IBC Liners
Form-fit liners are typically much easier to fill then the traditional pillow-shaped liners. Form-fits are best filled from the top utilizing a fill bridge.
As the name implies, form-fits are form-fitted to the inside dimensions of the container. Some people use the term cube liner because of the square or cube-shape of the liner when it is full.
Form-fit IBC liners typically allow for an easier fill and better evacuation with less residual product due to less folds and wrinkles, compared to a pillow liner.
There are 4 simple steps to filling a Form-fit style liner:
1. Drop the liner inside the container and square or align the bottom with the bottom of the container.
2. Slide the fill fitment into fill bridge slot.
3. Make sure bottom of liner is still aligned with the bottom of container and start filling.
4. A slight tugging of the corners of the liner may be necessary during the first fill, but once the
bottom is filled out and aligned, you should be able to walk away and let the liner fill.
Pillow IBC Liners
Pillow liners are typically filled from the bottom of the container with the bag sitting in a flat state on the floor of the container. The operator hooks up a hose and let’s the product fill the liner. Pillow style liners should not be used with a fill bridge or in top fill applications where the operator is hanging the liner.
Pillows can be more difficult for manual fills then a Form-fit and are best used with a cassette or automatic filler such as an aseptic fill liner.
There are typically 3 steps to filling a Pillow style liner:
1. Place the liner in the bottom of a container.
2. Reach over and hook up a hose (do not hang liner, as this causes distortion that may lead to a mis-fill).
3. During the fill, pull up corners or (ears) of liner to make sure no folds are restricting the product flow.
