Key Considerations for Export from Pakistan/South Asia
The 25kg Bag is King
In Pakistan, India, and Bangladesh, the 25 kg woven polypropylene (WPP) bag is the undisputed standard for wholesale and export markets. When a buyer requests a container quote, the pricing and capacity are almost always calculated based on 25kg bags.
Container Load Calculations (Critical for Export)
Bag Construction & Printing
Material: Woven Polypropylene (WPP) is used for its strength, durability, and breathability. For higher-value rice (like premium Basmati), often a plastic liner is added inside the WPP bag to protect against moisture.
Printing: Bags are custom-printed with the exporter’s brand, rice type (e.g., “1121 Basmati”), weight, origin, and other required certifications (e.g., ISO, HACCP). QR codes are also becoming common.
Palletization
For efficient and safe shipping, bags are almost always loaded onto wooden pallets and stretch-wrapped before being placed in a container. A standard pallet can typically hold 50 x 25kg bags (1.25 MT per pallet).
Vacuum Packing
For premium rice exports, especially to Western countries, 5kg and 10kg bags are often vacuum-sealed in plastic. This removes the air, drastically reduces the bag size, and extends shelf life by preventing insect infestation and oxidation. A vacuum-packed 5kg bag can be as small as 12″ x 8″ (30cm x 20cm).
Why These Dimensions Are Used in Pakistan
Cost Efficiency: These sizes are optimized to use fabric efficiently and minimize waste during manufacturing. The 25kg bag at 19×29″ is a very standard cut.
Rice Density: The dimensions are perfect for many popular Pakistani rice varieties that have a specific density. The bag is designed to be filled to a stable, stackable capacity without being too loose or overstuffed.
Strength and Durability: Specifying the bag weight (80g for 25kg, 120g for 50kg) is critical. A lighter, cheaper bag might tear during transportation, handling, or stacking, leading to major losses.
Logistics and Stacking: The rectangular shape and consistent dimensions allow for stable palletization. A standard pallet (40″ x 48″) can be stacked neatly with multiple layers of these bags.
Comparison with “International” Standards
| Bag Type | Pakistan Standard | International Standard | Advantages |
|---|---|---|---|
| 25kg Bag | 19″x29″ | 24″x14″ | More narrow and tall, larger surface area for printing |
| 50kg Bag | 23″x37″ | 30″x17″ | Narrower and taller, more efficient for container stacking |
Visual Explanation of the Bag Manufacturing Process
The WPP fabric is created as a continuous tube with a circumference of 38 inches.
Dimension: 38″ x 30″
The flat bottom is folded to create a gusset. Fold size is half the tube’s width (19″).
This creates the bag’s stable, flat bottom.
After sewing the bottom shut, the bag takes its final shape.
Dimension: 19″ W x 30″ H
When placing an order for rice from Pakistan, especially from Karachi-based mills, it is essential to specify exactly what you need:
- Net Weight: 25kg or 50kg
- Bag Dimensions: Precisely in inches or cm (e.g., 19″ x 29″)
- Bag Material Weight: e.g., “80 gram WPP bags” or “120 gram WPP bags”
- Features: Request a sewn seam (not just heat-sealed) for maximum safety and, if needed, a polyethylene liner inside for moisture protection
Always confirm the exact “bag specs” (material, dimensions, printing) with your packaging supplier and buyer before production.

How to Use the Rice Bag Calculator for Perfect Packaging
This tool helps Pakistani rice exporters and suppliers determine the optimal bag dimensions and weight. For standard sizes, simply select the net weight (e.g., 25kg) and get instant results. For custom bags, input your desired width and height, select the material, and get precise calculations for flat tube size and bag weight. Ensure your packaging is cost-effective, strong, and optimized for shipping.
SEO-Friendly FAQs Standard Bag Sizes Calculator with Custom Option
Q: Why is the 25kg bag the standard for rice export from Pakistan?
A: It’s the industry benchmark for wholesale and export. Container pricing and capacity are calculated based on 25kg bags, making it the most efficient and cost-effective unit for international trade.
Q: What does “Flat Tube Size” mean?
A: This is the dimension of the woven polypropylene (WPP) fabric tube before the bottom is sewn shut. The width is always double the finished bag’s width (e.g., a 19″ wide bag comes from a 38″ flat tube).
Q: How is the empty bag weight estimated?
A: The weight is calculated based on the surface area of the flat tube and the material type. Premium bags with liners are heavier, while vacuum-pack materials are lighter.
Q: How many 25kg bags fit in a 40-foot container?
A: Approximately 1,600 to 1,800 bags, equating to 40-45 metric tons. The exact number depends on palletization and bag dimensions.
Formula Detail
The tool uses two primary formulas:
- Flat Tube Width:
Finished Bag Width (inches) * 2 - Custom Bag Weight (Simplified):
(Flat Tube Width * Flat Tube Height) * Material Factor- The base algorithm uses the surface area multiplied by a factor (~0.07) to estimate grams.
- This factor is then adjusted (e.g., x1.2 for premium lined bags, x0.8 for vacuum packs).
- If provided, it can use more precise inputs like Fabric Weight (g/m²) or Denier for a more accurate calculation.
Real-Life Benefit for Visitors
