How to Choose Plastic Bags for Firewood & Kindling

Firewood and kindling need different bags because of how the wood behaves once it’s bagged. Firewood holds residual moisture and needs airflow, so vented bags with breather holes work best, typically a heavy duty 125 micron LDPE with six vent holes. Kindling and dry offcuts don’t need ventilation and are better suited to a tougher 100 micron bag without vents, since kindling pieces are smaller and more likely to puncture thin film. Getting this choice right stops bags splitting under weight and stops firewood sweating and going mouldy in storage. Get the bag wrong and firewood sweats, kindling punctures through thin film, or heavy loads split a bag that wasn’t built to carry them. Pinpak’s firewood and kindling bags cover both jobs, a vented heavy duty bag for firewood and a tougher unvented option for kindling and offcuts.

Why Firewood and Kindling Need Different Bags

Firewood cut from green or recently seasoned timber still holds moisture. Sealed in an unvented bag, that moisture has nowhere to go, and condensation builds up inside the bag. That trapped moisture leads to mould, a musty smell and firewood that’s harder to light, even if it looked dry when it was bagged. Bag thickness matters just as much as ventilation here. Our guide on choosing the right packaging thickness explains how micron rating affects how much weight and rough handling a bag can take before it splits.

Vented Firewood Bags, 125 Micron with Airflow Holes

Pinpak’s vented firewood bags measure 360mm plus a 200mm side gusset by 940mm, made from 125 micron natural LDPE. Six vent holes let air circulate through the bag, which helps residual moisture escape instead of condensing against the wood. The gusseted base also lets the bag stand upright when loaded, useful for retail display or stacking at a servo, produce store or firewood yard. These are sold in cartons of 125 bags, which suits most firewood suppliers packing standard loads for retail sale or delivery.

Heavy Duty Kindling Bags Without Vents

Kindling, offcuts and smaller dry pieces are better suited to Pinpak’s heavy duty bag, measuring 460mm by 700mm in 100 micron LDPE. This bag skips the vent holes, since kindling is usually already dry and doesn’t need airflow the way freshly cut firewood does. The heavier 100 micron film also resists punctures from sharp splinters and offcut edges better than a vented bag would, which matters when kindling pieces are smaller and sharper than split logs. Cartons hold 300 bags, a higher count than the firewood bag, reflecting the smaller average load size for kindling.

UV Resistance and Outdoor Storage

Firewood and kindling bags often sit outside, on a trailer, in a yard or on a retail shelf exposed to sun. UV exposure breaks down untreated plastic film over time, making bags brittle and more likely to split. Choosing a UV resistant bag extends how long stock can sit in storage or on display before the plastic starts to degrade, particularly through summer months when sun exposure is strongest.

What Happens to the Bag After Delivery

Firewood bags are usually opened, emptied and thrown out once the wood is stacked, which makes them a genuinely single use item in most households. LDPE bags like these can be recycled through soft plastic collection points rather than general rubbish. Our guide on recycling plastic packaging responsibly covers how to sort LDPE film correctly so it doesn’t end up in landfill by default. Letting customers know the bag is recyclable is a small detail that can matter to environmentally conscious buyers, particularly for firewood suppliers selling direct to households.

How to Choose the Right Bag for Your Business

If you’re bagging freshly cut or seasoned firewood, choose the vented 125 micron bag. The airflow matters more than the extra film thickness of the heavy duty option. If you’re bagging kindling, offcuts or genuinely dry, small pieces, the heavier 100 micron unvented bag will handle sharp edges better and doesn’t waste vent holes on wood that’s already dry. Suppliers who sell both should stock both bag types rather than using one bag for everything, since the wrong bag for the job shows up quickly as mould complaints or torn bags at the point of sale.

Frequently Asked Questions

What’s the difference between firewood bags and kindling bags?

The main difference is ventilation and thickness. Firewood bags are 125 micron with six vent holes to let residual moisture escape from freshly cut or recently seasoned wood. Kindling bags are a heavier 100 micron film without vents, since kindling is usually already dry and the extra thickness better resists punctures from small, sharp offcuts. Using a vented bag for kindling wastes the ventilation feature, while using an unvented bag for firewood risks trapped moisture and mould.

Why do firewood bags need vent holes?

Freshly cut or recently seasoned firewood still holds moisture inside the timber, even if the outside feels dry. Sealed inside a bag without airflow, that moisture has nowhere to go and condenses against the wood and the inside of the bag. Vent holes let air circulate through the load, helping moisture escape gradually rather than building up, which reduces the risk of mould, a musty smell and firewood that’s harder to light when it’s finally used.

What size are Pinpak’s firewood bags?

Pinpak’s vented firewood bags measure 360mm with a 200mm side gusset by 940mm, made from 125 micron natural LDPE and sold in cartons of 125. The heavy duty kindling bag measures 460mm by 700mm in 100 micron LDPE, sold in cartons of 300. The gusset on the firewood bag lets it stand upright when filled, which is useful for retail display or stacking during delivery.

Are firewood bags UV resistant?

Bags left outdoors on a trailer, in a yard or on display are exposed to UV, which breaks down untreated plastic film over time and makes it brittle. Pinpak’s firewood and kindling bags are built with heavy duty LDPE film suited to outdoor conditions, and it’s worth confirming UV treatment with your supplier if bags will sit outside for extended periods before use, particularly through summer months.

Can firewood bags be recycled?

Yes, firewood and kindling bags are made from LDPE, which can be recycled through soft plastic collection points rather than general household rubbish. Since these bags are typically opened and discarded once the wood is stacked, letting customers know they’re recyclable is a simple way for firewood suppliers to reduce landfill impact and appeal to environmentally conscious buyers. Stocking both a vented firewood bag and a heavy duty kindling bag covers every load without compromise.
