Minimum Order Quantity (MOQ): 2,000 bags
Writing “4 cross-corner loops” on an FIBC purchase order is a start, but it is not a complete lifting specification — because your supplier still needs to know how the loops are configured, how they interface with the bag, what equipment will handle them, and which approved FIBC drawing controls the finished construction.
This is where buyers get fooled by something that looks simple.
Four loops.
Four corners.
What could possibly go wrong?
Plenty.
The loops can be too short for your filling frame.
Too awkward for your forklift.
Different from the sample you approved.
Poorly matched to the bag footprint.
Incompatible with the customer’s unloading process.
Or technically cross-corner loops while still being meaningfully different from the design your plant has been using for years.
The solution is simple:
Buy to a controlled FIBC specification, not a generic loop description.
Cross-corner loops are lifting loops positioned around the upper corners of the FIBC so they extend across or project from the corner areas.
They provide four primary lifting points.
But the words “cross-corner loops” alone do not necessarily define every detail of the lifting configuration.
Your purchase order should reference the approved FIBC construction that controls those details.
The loops are part of the FIBC’s lifting system.
They’re not decoration.
They’re not handles added after the rest of the bag is designed.
They interact with:
The body construction.
Safe working load.
Filling equipment.
Forklift.
Bag dimensions.
Available headroom.
Discharge process.
Operator workflow.
That makes them an important purchasing specification.
Before talking about loops, define what’s going inside the FIBC.
The supplier may need to understand characteristics such as:
Product type.
Bulk density.
Flow characteristics.
Particle characteristics.
Moisture concerns.
Fine-powder concerns.
Food-related requirements.
Electrostatic considerations.
The product drives the package.
The loops are only one component.
How much product do you actually want in each FIBC?
That’s one of the first numbers that matters.
Don’t start with:
“We need a big bag with cross-corner loops.”
Start with the actual intended fill.
The complete FIBC should be designed around the application and load.
The safe working load needs to be appropriate for the intended application.
Do not attempt to determine FIBC capacity from:
Loop width.
Loop thickness.
Loop appearance.
Bag size.
Photos.
The complete FIBC construction determines its rated capability.
Specify the required load and buy accordingly.
How will the FIBC actually be used?
Consider:
Filling.
Lifting.
Palletization.
Storage.
Transportation.
Discharge.
The supplier needs enough information to understand the application.
A bag used in a simple forklift-handling process may have different operational requirements from one suspended from equipment at multiple stages.
Now define the basic lifting configuration.
For example:
Lifting Configuration: Four cross-corner lifting loops.
That’s your starting point.
Then control the relevant details through the approved FIBC drawing.
Loop height can affect compatibility with:
Forklift tines.
Filling frames.
Hooks.
Support arms.
Discharge equipment.
Facility headroom.
Don’t assume the supplier’s standard loop height is automatically right for your plant.
If the dimension matters, define it.
Call or Text us at 832.400.1394
The loop needs enough usable opening for the intended handling method.
The important question is:
What needs to go through or engage this loop?
That might involve:
Forklift tines.
Hooks.
Support equipment.
Filling-frame components.
If the opening is critical, define or reference it on the drawing.
Loop location is related to the bag’s upper corners and complete construction.
If precise position matters for your equipment, control it through the approved drawing.
Don’t assume two suppliers interpret the same generic wording identically.
Orientation can affect how the loops present themselves to the handling equipment.
If your operation relies on a particular configuration, show it clearly on the drawing.
This becomes particularly important when you’re trying to duplicate a proven existing FIBC.
Loop geometry doesn’t exist independently from the FIBC body.
A different footprint changes the relationship between the loops and:
Forklift tines.
Filling frame.
Pallet.
Support equipment.
Center of the bag.
If the footprint changes, reevaluate the loops.
The FIBC body has a height.
The loops extend above it.
Then the bag is lifted.
Your actual clearance requirement is greater than the body height alone.
Evaluate:
Warehouse ceiling.
Doorways.
Racking.
Filling equipment.
Discharge equipment.
Transportation equipment where relevant.
Cross-corner loops can be incorporated into different FIBC body constructions depending on the approved design.
Your PO should identify or reference the correct body construction.
Don’t order:
“Cross-corner bulk bag.”
and leave the entire body design open to interpretation.
The FIBC fabric is another controlled part of the bag.
The supplier should know the approved fabric construction required for the application.
Loop style does not determine fabric requirements.
If coating matters, state it.
Coating may be selected for reasons related to the product and containment requirements.
It has a completely different job from the lifting loops.
Don’t let one specification stand in for another.
Your top construction needs to match the filling process.
Common approaches may include:
Filling spout.
Duffle top.
Open top.
Other application-specific constructions.
The loops and top need to work together at the filling station.
If the bag has a filling spout, evaluate:
Loop height.
Bag suspension height.
Filling-spout position.
Filling-head position.
Operator access.
Equipment clearance.
The bag needs to hang where the filling equipment expects it.
A duffle top provides broader access.
Make sure the loop configuration doesn’t make it unnecessarily difficult to:
Open the top.
Position the bag.
Fill it.
Close it.
A good specification considers how features interact.
The bottom construction should match how the product leaves the FIBC.
That could involve:
Discharge spout.
Flat bottom.
Other controlled construction.
If the FIBC will be suspended during discharge, loop geometry becomes part of that process too.
Here’s where a bag can work beautifully at filling and fail operationally later.
The discharge station may have different clearance than the filling station.
Evaluate:
Body height.
Loop height.
Lifting equipment.
Discharge-spout length.
Receiving equipment.
Operator access.
You need enough space for the entire system.
If the application requires a liner, define it independently.
A liner may address:
Moisture.
Fine-particle containment.
Product-contact requirements.
Contamination concerns.
Other barrier requirements.
The loop style doesn’t tell the supplier whether you need a liner.
Fine powders may require additional attention to seam leakage.
Sift-resistant seam construction can help reduce product migration through certain stitched areas.
That’s a containment specification.
Cross-corner loops are a lifting specification.
Define both where needed.
Baffles help control loaded shape in appropriate FIBC designs.
They can potentially improve:
Loaded geometry.
Pallet utilization.
Warehouse utilization.
Trailer utilization.
But they have nothing to do with whether the bag has cross-corner loops.
If you need both, specify both.
If the application requires a particular electrostatic FIBC type, identify it separately.
Type A.
Type B.
Type C.
Type D.
Don’t assume loop construction determines electrostatic classification.
It doesn’t.
Type C FIBCs use conductive construction and require proper grounding during filling and discharge.
If the bag also needs cross-corner loops, those loops should be incorporated into the approved complete Type C construction.
Do not assume the loops themselves provide the required grounding solution.
Type D FIBCs use static-dissipative construction without requiring grounding of the FIBC itself.
Again, the cross-corner loops should be part of the approved complete design.
Avoid casually modifying specialized FIBC constructions without appropriate review.
Cross-corner loops do not make an FIBC food grade.
If the application involves food or food ingredients, separately define relevant requirements involving:
Product-contact materials.
Manufacturing controls.
Contamination controls.
Liner.
Traceability.
Documentation.
Customer requirements.
Loop style handles lifting.
Food-related specifications handle the product environment.
This is where your specification starts becoming operational.
What supports the bag during filling?
Four hooks?
Support arms?
A frame?
Other equipment?
Where are those support points?
How much clearance is available?
How high does the bag need to hang?
Those answers may influence loop dimensions.
Don’t write a loop specification in an office without thinking about the forklift.
Evaluate:
Tine width.
Tine spacing.
Tine length.
Operator visibility.
Mast.
Available maneuvering space.
Bag footprint.
Loop opening.
Loop height.
The forklift and FIBC need to work together.
How does the operator engage the loops?
Can they do it efficiently?
Does somebody have to manually reposition the loops?
Does the operator constantly adjust tine spacing?
Does the forklift have enough visibility?
These operational details can justify changes to the loop specification.
Watch your people.
Seriously.
Don’t guess.
Stand at the filling station and watch:
How they grab the empty bag.
How they position it.
How they mount the loops.
How they connect the filling top.
How they remove the filled bag.
How the forklift engages it.
Your operators can expose design problems faster than a specification sheet.
If your goal is for one operator to handle the FIBC without unnecessary assistance, state that operational objective during design discussions.
But don’t assume cross-corner loops automatically guarantee it.
Actual one-person handling depends on:
Equipment.
Bag position.
Loop geometry.
Pallet arrangement.
Visibility.
Facility procedures.
Validate the process.
This is easy to miss.
You optimize the FIBC perfectly for your plant.
Then it reaches the customer.
Their forklift is different.
Their discharge station is different.
Their ceiling is lower.
Their handling process is different.
If the customer interacts directly with the FIBC, understand their requirements too.

If the bag sits on a pallet, specify and test around the intended pallet configuration.
Consider:
Loaded footprint.
Overhang.
Bag orientation.
Loaded shape.
Loop position.
Forklift access.
The pallet and FIBC are part of the same logistics system.
An empty FIBC doesn’t tell you exactly how the loaded package will behave.
Depending on product and construction, the bag may:
Bulge.
Settle.
Change shape.
Shift.
A properly sized FIBC should be evaluated in its loaded state.
Tall bags, dense materials, and uneven product distribution can influence handling.
The lifting-loop design is only one part of loaded stability.
Make sure the overall bag geometry is appropriate for the product and intended fill.
Measure it.
Don’t guess.
You need room for:
Bag body.
Loops.
Forklift.
Lifting movement.
Facility obstacles.
A bag that technically fits under the ceiling may still be difficult to move safely through the actual facility.
Same principle.
Your warehouse may have plenty of vertical space.
Then the FIBC has to move through a doorway.
Evaluate the actual travel path.
If FIBCs move into or around warehouse racking, check:
Clearance.
Forklift positioning.
Loop access.
Loaded height.
Operator visibility.
Don’t design only for the filling station.
The loops generally aren’t the biggest driver of transportation efficiency.
Loaded dimensions and shape matter much more.
But the loop configuration can still affect:
Handling.
Clearance.
Loading.
Unloading.
Make sure the complete bag works through the logistics chain.
If the FIBC is printed, define:
Printed panels.
Artwork.
Artwork revision.
Colors.
Position.
Orientation.
Cross-corner loops and printing are separate requirements.
But they still need to coexist physically on the same bag.
Loop attachment areas can influence the usable print area near the upper portions of the bag.
Don’t place critical artwork where the lifting system makes it difficult to read.
Review the complete drawing.
If you need a document pouch, define:
Quantity.
Location.
Orientation.
Size.
Other relevant requirements.
Make sure it doesn’t interfere with the loops or handling process.
If variable labels are applied, provide a practical location.
Don’t put the label where:
The loop covers it.
The operator grabs it.
The forklift damages it.
Other equipment obscures it.
Think through the physical bag.
This is one of the most important steps.
The drawing can control:
Body construction.
Loop configuration.
Loop dimensions.
Top.
Bottom.
Liner.
Baffles.
Printing.
Document pouch.
Other physical features.
Then the purchase order references the drawing.
Much better than trying to describe everything in an email.
Specifications change.
Maybe the loop height changes.
Maybe the top changes.
Maybe the pouch moves.
Maybe the bag footprint changes.
Control those changes with revisions.
Then put the correct drawing revision on the purchase order.
This is tempting.
It’s also dangerous.
Instead of:
“Same as last order.”
use:
Part number.
Approved drawing.
Drawing revision.
Artwork revision where applicable.
Now everybody knows exactly which bag you’re buying.
A controlled part number makes repeat purchasing easier.
The part number should point back to the approved specification.
Now purchasing can reorder without reconstructing the entire bag from memory.
If cross-corner loops are important to the process, don’t let them be silently replaced with another configuration.
You can state that lifting-loop substitutions require approval.
If the supplier recommends another design, great.
Evaluate it first.
Drawings are valuable.
But if the handling configuration is changing, a sample can reveal issues the drawing won’t.
Test the bag.
Start with the empty bag.
Check:
Can the operator install it?
Can they reach the loops?
Do the loops fit the supports?
Does the top connect properly?
Does the bag hang at the correct height?
Is anything interfering?
Fix problems now.
Then fill it under appropriate operating conditions.
Watch:
How the bag expands.
How the loops behave.
How the top behaves.
How the product settles.
How the bag shape changes.
The loaded bag is the real package.
Use the actual forklift where practical.
Check:
Loop engagement.
Operator visibility.
Tine positioning.
Clearance.
Loaded-bag position.
Maneuverability.
Headroom.
This is where an apparently tiny loop change can become obvious.
If the FIBC is palletized, put it on the intended pallet.
Check:
Footprint.
Overhang.
Loaded shape.
Loop position.
Stability.
Forklift access.
Don’t approve the bag before checking the logistics configuration.
If the FIBC is suspended for discharge, take the sample through that process too.
Check:
Loop engagement.
Suspension.
Headroom.
Discharge access.
Operator access.
Downstream equipment.
Product flow.
The bag needs to work through the entire lifecycle.
Purchasing may approve the price.
Engineering may approve the drawing.
But the operator touches the bag.
Ask:
Was it easy to mount?
Were the loops easy to engage?
Did anything interfere?
Was the bag easier or harder than the current design?
That feedback can be extremely useful.

Avoid these:
Writing only “4 loops.”
Writing only “cross-corner.”
Not defining loop dimensions when they matter.
Ignoring loop opening.
Ignoring loop position.
Ignoring filling equipment.
Ignoring the forklift.
Ignoring customer equipment.
Ignoring discharge equipment.
Ignoring headroom.
Changing the bag footprint without reviewing loop geometry.
Changing body height without reviewing total lifted height.
Assuming larger loops mean higher capacity.
Assuming cross-corner loops automatically mean easier handling.
Assuming one-person handling without testing it.
Ignoring the safe working load.
Ignoring bulk density.
Ignoring target fill weight.
Ignoring the top.
Ignoring the bottom.
Ignoring the liner.
Ignoring electrostatic classification.
Ignoring food-related requirements.
Not referencing an approved drawing.
Not controlling the drawing revision.
Allowing unapproved substitutions.
Buying from a photograph instead of a specification.
Every one of these problems is preventable.
Before releasing the PO, verify four categories.
Product: Product type, bulk density, target fill weight, flow characteristics, and any special product considerations.
FIBC: Safe working load, body construction, fabric, coating, top, bottom, liner, seams, baffles where applicable, electrostatic classification, food-related requirements where applicable, printing, document pouch, and documentation.
Lifting System: Four cross-corner loops, loop dimensions, opening, position, orientation, filling-equipment compatibility, forklift compatibility, discharge-equipment compatibility, and headroom.
Control: FIBC part number, approved drawing, drawing revision, approved artwork where applicable, artwork revision where applicable, and substitution requirements.
That’s what purchasing should be controlling.
Don’t buy:
“A bulk bag with four cross-corner loops.”
Buy a controlled FIBC design.
Define the product.
Define the bulk density.
Define the target fill weight.
Define the safe working load.
Define the body construction.
Define the top.
Define the bottom.
Define the liner.
Define the electrostatic requirements where applicable.
Then define the lifting configuration.
Four cross-corner loops.
Correct dimensions.
Correct opening.
Correct position.
Correct orientation.
Compatible with the filling equipment.
Compatible with the forklift.
Compatible with the discharge station.
Compatible with the customer’s process where necessary.
Put it on the approved FIBC drawing.
Assign the drawing a revision.
Reference that revision on the purchase order.
Test a new design where appropriate.
Then lock it.
Because “four cross-corner loops” tells your supplier what general feature you want.
A controlled drawing and purchase order tell them exactly which bag you expect to arrive.
