Quick answer: Paper bags for coconut sugar must be strong enough to survive filling, stacking, transport and handling without tearing or bursting. Bag strength depends on the number and weight of paper plies, the liner and the closure. Safe stack height depends on bag strength, pallet pattern, warehouse humidity and the weight of the product. Interlocking pallet patterns, stretch wrap and dry storage help prevent damage.
Key takeaways – Multiwall paper and a PE liner give strength and moisture protection. – Stack height depends on bag strength and conditions. – Interlocking patterns keep pallets stable. – Humidity weakens paper, so keep warehouses dry.
How are paper bags built?
Bulk paper bags usually have several layers, or plies, of strong kraft paper. A food-grade PE liner inside protects the sugar from moisture. The bag is closed by sewing, gluing or heat sealing the liner, depending on the design.
| Feature | Effect on performance |
|---|---|
| Number of paper plies | More plies give more strength |
| Paper grade | Stronger paper resists tearing |
| PE liner | Keeps moisture out |
| Closure type | Affects leaks and strength at the top |
| Bag size and shape | Affects stability on the pallet |
Why does humidity matter?
Paper absorbs moisture from the air. In humid conditions, it becomes weaker and more likely to tear or bulge. Sugar inside can also absorb moisture if the liner is damaged. Keeping warehouses and containers dry helps protect both the bag and the sugar.
How should bags be stacked on pallets?
- Use clean, undamaged pallets; plastic pallets are often preferred for food.
- Stack bags in an interlocking pattern, alternating direction on each layer.
- Keep the edges of bags within the pallet edges.
- Flatten bags evenly so layers are level.
- Stretch-wrap the pallet for stability.
- Label each pallet with product and lot information.
How high can pallets be stacked?
Safe stacking depends on the bag strength, product weight, pallet condition, floor and warehouse humidity. Many warehouses limit pallets to one or two high, or use racking. Follow the supplier’s and packaging maker’s guidance and check for crushing, leaning or torn bags.
What damage should you look for?
- Torn or burst bags.
- Bags bulging at the bottom of stacks.
- Leaning or unstable pallets.
- Wet marks or water damage.
- Sugar leaking from seams.
Report damage quickly and separate damaged bags.
How can damage be reduced?
- Train staff to handle bags carefully.
- Avoid dragging bags across the floor.
- Use forklifts correctly with suitable pallets.
- Use corner boards or top sheets if needed.
- Check container floors for nails or sharp edges.
