Application
Wood Chips & Biomass Handling
Bulk bags for firewood, wood chips and pellets: abrasion, outdoor life, and why ventilation usually beats a liner.
Wood is hard on bags. Split firewood cuts loops and panels, chip edges abrade the body, and a yard forklift over rough ground finishes the job. Most failures in this application are handling failures, not weight failures.
Outdoor storage adds a second clock. Months in the sun degrade the fabric and the loop attachment, so UV stabilisation and loop construction matter more than an extra 20 GSM in the body.
Moisture behaves the opposite way to a mineral powder: a closed bag of green chips or pellets composts. Ventilation is usually what is wanted here, and a liner is usually wrong. Pellet loads also settle into a hard, dense mass, which the base seam has to be built for.
Application Summary
Handling firewood, wood chips and pellets in bulk bags: heavy, abrasive, often wet loads that are stacked outdoors and moved with rough handling.
Typical Customers & Materials
Firewood and pellet producers, sawmills, biomass traders and garden-centre suppliers. The buyer is usually an owner or operations manager who wants a bag that survives a wet yard and a forklift, not a bag with a liner.
Primary Job
Get a heavy, abrasive, sometimes wet load from the yard to the end user without the bag tearing, and without the product composting or going mouldy on the way.
Operating Process
- Filling
- Lifting
- Storage & Transport
- Discharge
Operating Process Notes
Filling is usually by hand or from a hopper into an open-top bag, so the bag is dragged and dropped during filling. Lifting is by forklift or a tractor loader on four corner loops, often over rough ground. Storage is outdoors for weeks to months. Discharge is by cutting the base or tipping the bag.
Key Risks
- Abrasion
- Puncture
- UV Exposure
- Moisture
- Ventilation
Key Risks - Additional Notes
Abrasion and puncture dominate: split firewood and chip edges cut loops and body panels, and rough yard surfaces and forklift tines do the rest. Outdoor storage for months makes UV stabilisation a specification item rather than a default, and the loop attachment is usually the first thing to fail on a bag that has been sitting in the sun. Moisture in a closed bag turns wood chips and pellets into a compost heap, so ventilation is usually wanted instead of a liner. Pellet loads are dense and settle, so the filled bag can become very hard and the base seam has to be built for it.
Selection Notes
Choose the fabric and loop attachment for the handling, not for the weight alone: a heavier loop panel with extra stitching usually outlasts a heavier body fabric. If the product is stored wet or green, leave it ventilated and skip the liner. If the buyer wants the bag to survive a second season, say so at quotation stage - that is a UV and loop decision, not a fabric weight decision.
Scope & Limitations
This page covers firewood, wood chips and pellets in standard FIBC constructions. It does not cover bulk truck or walking-floor trailer delivery, and it does not set the customer's drying or storage regime.
Information Required
Product and moisture content at filling Required
Firewood, chips or pellets, and whether the product is dry, green or wet when bagged.
Fill weight and SWL Required
The weight the yard actually fills - pellet loads settle and get heavier than expected.
Handling method Required
Forklift, tractor loader or crane, and whether bags are dragged during filling.
Storage location and duration Required
Open yard, covered yard or indoors, and how many months the bag has to last.
Ventilation requirement
Whether the load needs airflow to avoid mould, or a moisture barrier instead.
Reuse expectation
Whether the bag is used once or has to survive a second season, which changes the UV and loop specification.
