Bulk bags wanted

The bags we can buy back

A buy-back bag goes back into someone else's operation, usually holding sand, gravel, aggregate or a feed or mineral product. That next user is trusting the label. So every condition below is about whether the label still tells the truth.

• Safety factor 6:1, multi-trip, printed on a label you can still read in full
• SWL, maker and dimensions legible, so the bag can be matched to a request
• Loops whole, with no cut, frayed or pulled stitching
• Body and seams with no holes, tears, burns or patches
• Prior contents clean and non-hazardous, and known
• Stored indoors or under cover, out of sun, and dry
• Emptied fully, with liners removed

Why each rule exists

The 6:1 rule comes from testing. Multi-trip standard-duty bags are proven to six times SWL and pass a long compression test; single-trip bags are proven to five times and the maker recommends one use. Calling a 5:1 bag reusable would mean trusting a margin nobody tested for.

Labels matter because a bag with no readable SWL has no rating anyone can rely on. Loops matter because they carry the whole weight on every lift. Sun matters because UV weakens polypropylene from the surface in, and the manufacturer guidance says not to lift a bag after long sun exposure. Dryness matters because wet bags mould and wet product clumps.

Prior contents matter most of all. A buyer filling the bag with gravel doesn't want a residue they didn't plan for, and a bag that held something hazardous can't be passed on at all.

What we can't buy

Any 5:1 single-trip bag. Bags with torn or missing labels. Bags that held hazardous material, or whose prior contents nobody on site can name. Bags that sat outdoors, or that smell of mould. Bags cut open at the bottom to discharge, since the bottom can't be closed again.

Food-contact bags are a special case. They may be in excellent shape, but a used bag is never offered for food, so if we take them, they go to non-food work only. Bags that held static-sensitive product lose the assurance of their static type after use and are treated the same way.

Showing us what you have

Photos save a wasted truck. Send one clear shot of a label from each size or batch, one of a typical bag laid out, and one of the stack or bale. Add the count per size and the product the bags held. We'll sort the lot on paper and tell you which part fits buy-back and which part goes for recycling, before a pickup is booked.

How a mixed lot gets sorted

Few stacks are all one thing. This is how each kind of bag in a typical lot is routed.

Details the next user will ask about

A reconditioned bag is matched to a new request by its spec, so the more of it we can read, the better the bag's chances. Dimensions, spout diameters top and bottom, loop height, coated or uncoated fabric and whether the body is baffled all go into that match. A batch of identical bags is easier to place than a scatter of one-offs, so a lot of fifty bags all the same spec is worth more attention than fifty different bags.

Inspection on arrival is final. Bags that looked fine in a photo but turn out damp, stained or weakened go to recycling at the other end, and the offer adjusts accordingly. Honest photos avoid that surprise.

Spot checks you can do yourself

Before photographing anything, give a sample of bags a quick once-over. Hold the fabric up to a bright light and look for pinholes. Tug each loop firmly and look at the stitching where it meets the body. Rub the outer surface with a thumb: a chalky, powdery residue means sunlight has started breaking the fabric down. Open the top and look inside for caked product, damp patches or mould, and smell it.

If a sample of ten fails on two or more counts, assume the stack is recycling rather than buy-back and say so in your request. It saves an inspection and sets the right expectations.
