How it works
The liner holds the liquid and the cardboard cradle holds the liner. When the product is gone, the liner is discarded and the cardboard is recycled. There is no cage to straighten, no bottle to wash and no valve to retest, which is why the format is single use.
That is also why there is little to grade. A bag-in-box is either unopened and sound, or it is empty and goes to the recycling stream. The grader does not map to it, because cage, bottle and base are not parts here.
| Part | What it is | Reused? |
|---|---|---|
| Liner | Plastic bag that holds the product | No |
| Cradle | Corrugated outer box | Recycled as cardboard |
| Fitment | Bottom spout or valve | No |
| Pallet | Under the cradle | Often, if sound |
Who asks about them
Food and beverage processors that ship ingredients in liquid form, like concentrates and syrups, use bag-in-box to avoid washing totes. A Chino or Rancho Cucamonga food plant might receive them by the pallet. A buyer searching for "ibc totes" can be looking for a caged tote and land on this format by accident, so check the spec before you ask.
If you hold an empty bag-in-box and want it gone, the cardboard recycles with corrugated and the liner goes to trash or film recycling depending on what it held. If you are looking to reuse a rigid tote, caged totes are the page for you.
Ask these in the request
- Is the container unopened, or empty?
- What did it hold, and is the SDS available?
- How many, and on what kind of pallet?
- Do you need it removed or do you want one to buy?
Where a bag-in-box tote fits
A bag-in-box tote puts a disposable liner inside a rigid shell, so the product touches the bag and not the wall. That makes it popular where a clean fill is the whole point and the shell is simply protection. Think of syrups, juices and ingredients that cannot afford carry-over from a previous fill.
The shell is reusable and the bag is not. When you inspect one, the questions are about the shell: dents, cracks, a damaged outlet fitting and a missing valve. The liner you can replace; the structure you cannot. Ask whether liners are available in the volume you need before you commit to the shell.
Liner questions to settle
Find out the liner material, the fill volume it was made for and the type of outlet it fits. A liner that is too large wrinkles and traps product; one too small tears. If you do not know the liner part number, send a photograph of the old outlet and the label on the shell.
Ask also whether the liner is single-use by design. Re-filling a liner that was meant to be used once is a common way to spoil a batch.
Storage of spare liners
Keep spare liners flat, dry and out of the sun. Heat softens the film, and a liner stored folded can crack at the folds.
