The 39x39x55 bulk bag is a near-square, high-capacity FIBC that sits perfectly between standard 35×35 bags and full 40×40 industrial footprints. It’s built for operations that want more volume and stability than smaller bases provide—without jumping all the way to the biggest square sizes.
This is a capacity upgrade with control.
What a 39x39x55 bulk bag actually means
A 39x39x55 bulk bag measures:
-
39 inches wide
-
39 inches deep
-
55 inches tall
This configuration delivers:
-
a wider, more stable base than 35×35
-
meaningful height for higher volume
-
better balance than narrow tall bags
It’s often chosen when buyers want taller bags that still feel planted during handling.
Why buyers choose 39x39x55
1) You want more volume without going full 40×40
This size gives you most of the benefits of a 40×40 footprint with slightly less floor space.
2) You want stability at height
At 55″ tall, footprint matters. The 39×39 base improves balance and reduces sway.
3) Your product is light-to-medium density
This size allows you to load more product before hitting weight limits.
4) You want fewer bag changeovers
More capacity per bag = fewer fills, fewer swaps, and higher throughput.
Typical capacity behavior for a 39x39x55 bulk bag
Capacity varies by density and construction, but this size is commonly selected when:
-
volume matters more than weight
-
operations want taller bags without instability
-
facilities need a square footprint for stacking consistency
This is a production-grade size, not a specialty outlier.

Construction options (important at 55″ height)
As height increases, construction directly affects performance.
U-Panel
-
Cost-effective
-
Strong general-purpose option
-
May bulge slightly at full load
4-Panel
-
Squarer profile
-
Cleaner pallet edges
-
Preferred for neat stacking
Circular
-
Economical at scale
-
Shape depends on fill discipline
Baffle (recommended for clean stacking)
-
Maintains square shape
-
Reduces bulging
-
Improves stack appearance and stability
Coated vs uncoated fabric
Uncoated fabric
-
Breathable
-
Lower cost
-
Works for many general materials
Coated fabric
-
Improved sift control
-
Better moisture resistance
-
Cleaner warehouse environment
For fine or dusty materials, coated fabric is often the better choice.
Top options (how you fill)
Duffle top
-
Fast filling
-
Flexible access
-
Common for manual operations
Spout top
-
Controlled fill
-
Cleaner operation
-
Preferred for automated or dust-sensitive lines
Open top
-
Simple
-
Often paired with liners or covers
Bottom options (how you discharge)
Spout bottom
-
Controlled discharge
-
Clean flow
-
Ideal for powders and granules
Flat bottom
-
Used when dumping or mechanical discharge is in place
Closed bottom
-
Used in specialized workflows
Liner options (commonly used)
Liners are often added when:
-
moisture protection is required
-
contamination control matters
-
fine powders need extra containment
Common liner types:
-
tabbed liners
-
form-fit liners
-
PE liners in multiple mil thicknesses
New vs used 39x39x55 bulk bags
Used / reconditioned bulk bags
A good option when:
-
product is non-hazardous
-
cost savings matter
-
cosmetic variation is acceptable
New bulk bags
Preferred when:
-
specifications must be consistent
-
product sensitivity is higher
-
repeatability matters long-term
