Ventilerade Big Bags
Mosquito net & ventilated striped fabric · ISO 21898 certified
Ventilated Big Bags
Built for products that need to breathe — firewood, logs, green waste and biomass. Open mesh or ventilated striped fabric lets air circulate so your contents stay dry, fresh and intact.

What Is a Ventilated Big Bag?
Most big bags are designed to contain their contents as tightly as possible. Ventilated big bags do the opposite: they are built to let air flow freely through the fabric walls, keeping the contents dry, fresh and in good condition during storage and transport.
The open weave fabric — available in two types — replaces standard woven PP with either alternating mesh strips or a fully open mosquito net construction. The 160 g/m² fabric provides good resistance to sharp and ragged materials like wood splinters, while the open structure ensures continuous airflow through all four bag walls.
Ventilated Striped Fabric
Alternating bands of standard close-weave and open-weave PP. The dense bands provide structural strength; the open bands allow airflow. A cost-effective solution for moderate ventilation needs — standard log bags, garden waste, and agricultural use.
Best for: garden waste, green waste, log bags
Mosquito Net Fabric (Open Mesh)
Fully open-weave fabric with large, regular gaps between all tapes — maximum airflow across the entire bag surface. The open mesh flexes around sharp, splintered log ends rather than being cut by them. Logs remain fully visible for retail display.
Best for: firewood, logs, biomass chips, retail log sales

Buy →Why Your Product Needs a Ventilated Bag
| Product | What happens in a sealed bag | Why ventilation solves it |
|---|---|---|
| 🪵 Firewood & logs | Trapped moisture causes mould, increases weight, reduces burning quality | Wood continues drying after bagging — moisture content keeps falling |
| 🌿 Green waste | Active decomposition generates heat and gas — anaerobic conditions develop | Ventilation prevents overheating and keeps waste in good condition en route to processing |
| 🌱 Fresh compost | Composting generates heat and CO₂ — sealed bags can deform and burst | Gases escape freely — no pressure build-up, no anaerobic conditions |
| 🌾 Biomass chips | Moisture retention causes degradation and reduced calorific value in storage | Moisture released during storage — biomass maintains quality and energy content |
⚠️ Ventilated bags are not suitable for dusty products
The open weave that lets air in also lets fine particles out. For dusty products, powders, or materials that require full containment, use a coated bag or a bag with a PE liner. Ventilated fabric is for coarse products where airflow is beneficial.
Our best-selling ventilated product
Log Bags & Firewood Bags
Firewood has two specific characteristics that make standard woven bags a poor choice — sharp, splintered log ends that cut standard PP fabric, and the need for continued drying after bagging. Our log bags use mosquito net fabric that solves both problems at once.
🌬️ Maximum airflow
Airflow through the entire bag surface — not just open strips. Wood continues to dry after bagging, helping you meet moisture content requirements for retail sale.
🪵 Sharp-edge resistant
The open mesh flexes and yields around sharp, splintered log ends rather than being cut by them. Standard woven bags fail quickly in firewood applications.
👁️ Full product visibility
Logs are fully visible through the mesh for retail display — buyers see exactly what they are purchasing. Ideal for firewood retail and farm shop sales.
📋 Ready to Burn compatible
Ventilated bags allow firewood to continue drying toward the <20% moisture threshold. Sealed bags trap moisture and can push certified wood fuel back above the limit.
| Moisture content | Wood condition | Ventilated bag? |
|---|---|---|
| Below 20% | Ready to burn — ideal for retail sale | YES — maintains quality |
| 20–25% | Drying wood — still improving | YES — continues to dry in bag |
| Above 25% | Wet wood — needs further seasoning | YES — essential if bagged at all |
| Above 40% | Freshly cut green wood | Season first — do not bag yet |
Who uses them
Industries and Applications
🪵 Firewood & Forestry
The primary application. Log bags for firewood retail and trade, seasoning storage, and biomass supply chains. Mosquito net fabric is the standard choice for all firewood applications.
🌱 Garden & Green Waste
Seasonal garden clearance, prunings, branches and green waste for composting facilities. Ventilated striped fabric keeps green waste in better condition en route to processing.
🔥 Biomass & Energy
Wood chips, sawdust, shavings and biomass materials where moisture control maintains calorific value. Ventilated bags protect quality from field to processing plant.
🏪 Retail & Farm Shops
Firewood and produce in bags displayed at point of sale. The full product visibility through mosquito net fabric is a key selling point — customers can see exactly what they are buying.
🏗️ Waste Processing
Wood waste from dismantling, sawmill by-products, and wood offcuts. Ventilated bags prevent heating and degradation during temporary storage before recycling or energy recovery.

Ventilated striped fabric alternates bands of standard close-weave PP with bands of open-weave fabric — giving moderate airflow. Mosquito net fabric has large, regular gaps across the entire bag surface — giving maximum airflow and superior sharp-edge resistance. For firewood, mosquito net is the preferred choice. For garden waste or agricultural use, ventilated striped fabric is often sufficient and more cost-effective.No. The open mesh structure means less PP per unit area, but the mesh pattern and tape quality are engineered to the required Safe Working Load. A correctly specified mosquito net bag is as strong as a standard bag at the same SWL rating. All 123BigBags ventilated bags are ISO 21898 certified.No. Ventilated bags are not suitable for products that generate significant dust — the open weave allows fine particles to escape. For dusty products, use coated bags or bags with PE liners. Ventilated fabric is designed for coarse products where airflow is beneficial.Yes — outdoor stacking during seasoning is standard practice in the firewood industry. Stack no more than 2 high and ensure good airflow around and between bags. Inspect bags after 3–4 months of outdoor exposure — ventilated fabric is robust, but UV exposure still applies. Apply the 6-month inspection rule and replace any bag showing signs of UV degradation.No. At 123BigBags we sell by the unit — from a single bag to full pallet quantities. Volume pricing applies automatically at checkout for larger orders.
