Tonne Bag with Open Top 85cm x 85cm x 85cm

Tonne bags are large woven polypropylene bulk bags for storing, moving and lifting loose materials on site. This bag has an open hemmed top for easy filling and four corner loops for lifting by forklift or crane, with a safe working load of 1 tonne. It is made from UV stabilised fabric, so it can be stored outdoors.

How Loops Stitched Into the Fabric Add Strength

Loops attached only at the seam put the full weight of a loaded bag on a few stitches. On site, that is where loops can tear when a forklift or crane takes the strain. Each loop on this bag is stitched into the fabric itself, giving extra strength for the lift.

Key Features

  • 1 tonne safe working load: lifts and holds up to 1,000kg of aggregates or waste.

  • Open top: fills quickly from a digger bucket, shovel or chute.

  • Four stitched lifting loops: 40mm x 300mm corner loops, stitched into the fabric for extra strength.

  • UV stabilised fabric: suits outdoor storage on site.

  • Woven polypropylene: a tough weave that holds heavy, loose materials.

Typical Users and Projects

Builders, groundworkers and landscapers use tonne bags to store and move loose materials around construction sites, yards and landscaping projects. They are filled by hand, digger or chute, then lifted by forklift, telehandler or crane. They suit any job where loose materials need containing, separating or moving in bulk.

Typical applications

  • Storing sand, gravel and aggregates on a building site.

  • Separating waste streams for recycling during demolition or strip-out.

  • Collecting rubble and spoil for removal by telehandler or crane.

  • Holding green waste and soil on landscaping projects.

  • Moving loose materials between work areas on a large site.

How to use

Step 1: Open the bag on firm, level ground with the four loops standing upright.
Step 2: Fill it evenly, keeping the load within 1 tonne and below the top hem.
Step 3: Attach all four loops to the forklift tines, crane hook or lifting gear.
Step 4: Lift slowly and keep everyone clear of the suspended load.
Step 5: Lower the bag onto firm, level ground and release the loops.
Step 6: Once emptied, dispose of or recycle the bag rather than lifting it again.

Common mistakes

  • Lifting the bag by one or two loops instead of all four.

  • Lifting a used bag a second time.

  • Overloading with dense materials such as wet sand, which can reach 1 tonne before the bag is full.

  • Standing under or next to a suspended bag.

  • Dragging a loaded bag across the ground, which can tear the base.

Safety

Plan every lift in line with the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) and HSE guidance. Check the loops and fabric for damage before lifting, and never exceed the 1 tonne SWL. Keep people out of the lifting area and never stand under a suspended bag.

Maintenance

Store empty bags flat, dry and out of direct sunlight until needed. Inspect each bag before use and don’t use one with cut loops, torn fabric or damaged stitching.

Frequently Asked Questions

Q: What does SWL 1 tonne mean on a tonne bag?
A: SWL stands for safe working load. It is the maximum weight the bag is designed to hold and lift, 1 tonne (1,000kg) for this bag. Never load or lift beyond it.

Q: What does 85cm x 85cm x 85cm mean?
A: It is the length, width and height of the bag. That gives a capacity of about 0.6m3, although dense materials reach the 1 tonne limit before the bag is full.

Q: What does single use mean?
A: The bag is designed for one fill-and-lift cycle. After that, the fabric and loops may be weakened, so don’t lift it again. Empty it and dispose of or recycle it.

Q: What are tonne bags not suitable for?
A: They are not suitable for loads over 1 tonne, for lifting a second time, or for lifting by fewer than four loops. They also aren’t suited to very fine powders, liquids or hazardous materials.

Q: What is the difference between a tonne bag and a rubble sack?
A: A rubble sack is a small bag carried by hand, usually holding up to 25kg. A tonne bag holds up to 1,000kg and is lifted by forklift or crane using its four loops.

Q: How do I lift a tonne bag safely?
A: Attach all four loops to the forklift tines or lifting gear, lift slowly and keep everyone clear. Plan the lift in line with LOLER and never stand under a suspended bag.

Q: How much sand fits in a tonne bag?
A: Dense materials such as wet sand can reach the 1 tonne limit before the bag is full. Fill by weight, not by volume, and stay within the SWL.

Q: How should I store empty tonne bags?
A: Keep them flat, dry and out of direct sunlight until needed. Check each bag for damage before use.
