Proper Installation of IBC Liners Ensures Complete Evacuation

It is important to fill an intermediate bulk container liner correctly. There are proper steps to take when preparing the set-up. Following these steps will ensure that the installation goes smoothly and, most importantly, will avoid you from possible problems, such as: 

• Incorrectly unfolding the liner
• Trapping the liner film behind the fitting
• Causing improper or incomplete evacuation of product

Before beginning this process, be mindful of a few general tips. Adhering to these while following the steps below will help avoid the potential issues mentioned above: 

• Place liner in the bin correctly
• Avoid gaps in the corners of the bin
• Avoid folds in the liner that can block the dispense fitting, preventing proper and full product evacuation
• Avoid tools that can pinch or puncture the liner

Below are the key steps for filling an IBC liner.

Instructions for Top Filling an IBC Liner

1. Prepare CL285
   1. Remove lid
   2. Unfold CL285
   3. Open drop door
2. Insert the liner into the container
   1. Take liner from the carton box or bulk bin
   2. Place liner into the CL285 from the back
   3. Unfold the liner one part to the left, to the right, and to the back
   4. Insert the Din50 valve into the bottom discharge
   5. Verify all corners are square and aligned to prevent gaps and folds
   6. Close drop door
3. Connect to fill bridge
   1. 3” or 2” fitting
   2. Place fill bridge on top of container
   3. Lock fill fitting into fill bridge
   4. Attach adapter
   5. Confirm all four corners are properly positioned, with no folds
   6. Confirm back of the liner is properly positioned to the back of the CL285
4. Attach source and begin filling*
   1. During filling, verify no gaps
   2. If there are gaps or the need to correct the position of the liner, pull towards corners, laterally. Do NOT pull straight up.
   3. Once container is half-way full, check liner positioning; if corrections are needed, from the corners, push down and in (towards the center of the container) to reposition the liner

*NOTE: Do not stop the filling process; it is designed to fill 1000L in one go.
