Agriculture & Feed

Bulk bags for grain, seed and compound feed: the products are light, so a bag reaches its fill volume before its weight. It has to keep the load stackable and dry until it is fed, and the liner or the ventilation follows the fill temperature.

500–1,000 kg Typical Fill Weight

The range the filed grain workflow is quoted on

Volume first Low Bulk Density

A light product: the bag fills to volume before weight

Warm fill Condensation Control

A warm fill closed in a sealed liner can condense

Additive package Outdoor Storage

UV additive is set against how long filled bags wait outside before the lot moves.

Stacking Stability For Light Loads A U-panel or baffle construction buys more stability per bag than a heavier fabric does.
Liner Decided By Fill Temperature The liner follows the fill temperature and the storage period, not habit.
Ventilation Instead Of A Liner Where the product has to breathe, ventilation replaces the moisture barrier; the two are not used together.

THE 4 PACKAGING RISKS THAT DECIDE THE SPEC IN AGRICULTURE & FEED.

Moisture decides most grain and feed loads and low density decides the rest: the risks the filed grain workflow names.

Risk 01 · Moisture

Condensation On A Warm Fill

A warm fill closed in a sealed liner can condense in transit, and a wet pallet underneath rejects a load.

QINFENG Answer: Decide the liner on the fill temperature and the storage period.
Risk 02 · Bulging

A Bag Filled To Its Volume

These products are light, so the bag fills to volume before weight: the body bulges and the stack becomes unstable.

QINFENG Answer: Treat it as a stacking problem: a U-panel or baffle bag buys more stability.
Risk 03 · Leakage

Fine Feed At The Seam

Fine compound feed works through a seam in transit: product loss, and housekeeping at the pallet and the spout.

QINFENG Answer: Seam construction and stitch count are inspected on production samples.
Risk 04 · Ventilation

A Product That Has To Breathe

Where the product is filled warm, ventilation matters more than a liner, and a closed bag holds moisture in.

QINFENG Answer: Specify a ventilated construction instead of a liner, with the mesh pattern set from the storage period.

ENGINEERED FIBC CONSTRUCTIONS FOR AGRICULTURE & FEED.

Configured for grain, seed and feed: a low-density load that must stay dry and stack level.

U-Panel FIBC 600 x 400 px Squarer filled footprint

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-grade FIBC 600 x 400 px Hygiene decisions are made explicit

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

SPECIFIC APPLICATIONS & PROCESS FLOWS.

The setups we have written up for grain elevators, feed mills and agricultural traders.

/ Technical Quality

TESTING, COMPLIANCE & QUALITY ASSURANCE.

What the filed grain workflow asks us to hold to, and how each item is checked; market-specific requirements are confirmed per project.

1. Requirements & How We Verify Them

Fill Volume And Weight Bulk density and fill weight are read together, because a light product fills to volume first.
Liner And Fill Temperature Whether the product is filled warm from a dryer is confirmed before the liner is quoted.
Seam Containment Seam construction and stitch count are checked on production samples against the drawing.

2. The Configuration Range We Quote

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
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

Each row is the range its product record states; the confirmed figure is set per project.

Agriculture & Feed Quotation Checklist

1. Product and bulk density:
Grain, seed or feed type, and the bulk density, which decides whether the bag fills by weight or by volume.
2. Fill temperature:
Whether the product is filled warm from a dryer, and the typical temperature at filling.
3. Storage period and conditions:
Indoor or outdoor, stacked how high, and for how long the bag has to hold the product in good condition.
4. Fill weight and SWL:
The weight the mill actually fills, and the SWL to be marked.
