The liner carries the product and the body carries the load, so its material and fit are set
A liner that stays in place, a spout that does not shed fibre, a bag the plant can inspect
Where bags are emptied in a controlled area, a clean discharge beats a heavier fabric
Batch and liner records are kept so a delivered lot traces back to the run.
THE 4 PACKAGING RISKS THAT DECIDE THE SPEC IN FOOD & INGREDIENTS.
Foreign bodies, moisture and discharge cleanliness decide a food ingredient bag; fabric strength is rarely limiting. These are the risks the filed workflow names.
Foreign Bodies In The Product
A liner that shifts during filling, a spout that sheds fibre, or loose handling between the sewing floor and the pallet.
Caking In Flour And Starch
Moisture pickup shows as caking in flour and starch and lumps in sugar, which the receiving plant rejects.
Fine Flour Working Through Seams
Fine flour escapes at the seam: product loss and housekeeping at the fill head.
Pallet Nails And Forklift Tines
Puncture risk comes from pallet nails and forklift tines more often than from the product itself.
ENGINEERED FIBC CONSTRUCTIONS FOR FOOD & INGREDIENTS.
Configured for flour, starch, sugar and blends where the liner and a clean discharge decide.
Food-grade FIBC
A bulk bag built around hygiene rather than around load: liner choice, closure, foreign-body control and batch traceability are the decisions that matter. The requirements that apply are confirmed per market and per project.
- Size: 75 x 75 x 110 cm to 100 x 100 x 130 cm (typical)
- Liner: Food-contact-intended PE film, loose or form-fitted
- Liner closure: Tied, heat-sealed or zip closure
Baffle FIBC (Q Bag)
A four-panel FIBC with internal baffles or corner ties that hold a near-cube shape whether the bag is empty or part-filled. Built for loads that have to stack square in a container or on…
- Size: Square base 85 x 85 x 85 cm to 105 x 105 x 120 cm
- SWL / Safety Factor: 500-1,250 kg at 5:1; 1,000-2,000 kg at 6:1
- Top: Duffle, filling spout, or open top with separate cover
U-Panel FIBC
A flat-bottom FIBC whose body is one U-shaped panel joined to two side panels, giving a squarer filled footprint than a tubular bag. It is the usual answer when a filled bag has to…
- Size: 75 x 75 x 110 cm up to 100 x 100 x 150 cm (typical)
- SWL / Safety Factor: 500 kg to 1,200 kg at 5:1; 6:1 on request
- Top: Open top, filling spout, duffel top, or skirt with tie cord

Food Ingredient Packaging
Bulk bags for flour, starch and sugar: hygiene-led construction, complete discharge, and a liner that protects the product rather than the bag.
TESTING, COMPLIANCE & QUALITY ASSURANCE.
What the filed ingredient workflow asks us to hold to, and how each item is checked.
1. Requirements & How We Verify Them
| Liner Fit And Closure | Liner fit is checked on a trial fill, and the closure from fill to discharge. |
|---|---|
| Foreign-Body Controls | Seams and loops are arranged away from the fill, and recorded per batch. |
| Batch Identification | A specification version, a sample reference and a batch number run through. |
2. The Configuration Range We Quote
| Food-grade FIBC · Size | 75 x 75 x 110 cm to 100 x 100 x 130 cm (typical) |
|---|---|
| Food-grade FIBC · Liner | Food-contact-intended PE film, loose or form-fitted |
| Baffle FIBC (Q Bag) · Size | Square base 85 x 85 x 85 cm to 105 x 105 x 120 cm |
| Baffle FIBC (Q Bag) · SWL / Safety Factor | 500-1,250 kg at 5:1; 1,000-2,000 kg at 6:1 |
| U-Panel FIBC · Size | 75 x 75 x 110 cm up to 100 x 100 x 150 cm (typical) |
| U-Panel FIBC · SWL / Safety Factor | 500 kg to 1,200 kg at 5:1; 6:1 on request |
Each row is the range its product record states; the confirmed figure is set per project.
Food & Ingredients Quotation Checklist
- 1. Product and its moisture behaviour:
- Flour, starch, sugar or a blend, and whether it cakes or picks up moisture readily.
- 2. The hygiene standard you buy against:
- Your own supplier standard or the scheme you are audited to, so we can confirm what we can evidence.
- 3. Liner requirement:
- Loose, glued-in or form-fit liner, and the gauge if you already specify one.
- 4. Fill weight and SWL:
- Actual fill weight, and the SWL to be marked.
