Mesh bags for onions, potatoes and produce: what to specify
Mesh bags look simple because everyone has seen one. That is the trap. A produce buyer may ask for “onion bags” and expect the supplier to know the rest. The supplier may quote the cheapest matching bag. Then the problem appears later: wrong size, weak seam, bad color, poor closure, awkward packing or a bag that does not match the buyer’s filling process.
For mesh bags, the product is simple. The use case is not.
In short
For produce mesh bags, specify material, bag dimensions, capacity, mesh construction, color, closure type, label or print requirement, packing format, quantity and destination. For onions, potatoes, garlic and similar produce, ventilation is the main reason mesh bags exist, but ventilation alone is not the whole specification.
Why mesh bags are used
Produce such as onions and garlic needs air movement during storage and transport. Mesh bags help ventilation and visibility while keeping the pack unit easy to handle.
That does not mean any mesh bag works for any produce. A bag for 25 kg onions, a small retail firewood bag and a garlic pack are different products even if they are all “mesh”.
Core specifications to confirm
| Specification | What to send |
|---|---|
| Produce type | Onion, potato, garlic, citrus, firewood, shellfish, other. |
| Bag size | Width x length, usually in mm or cm. |
| Capacity | Example: 5 kg, 10 kg, 25 kg, 50 lb. |
| Material | PP leno mesh is common for many produce bags. |
| Color | Often crop or market specific. |
| Closure | Drawstring, stitched, header, clip or open-mouth. |
| Label/printing | Plain, printed band, label, custom artwork. |
| Packing | Bales, cartons, pallet quantity, compression. |
| Quantity | Pieces, cartons or container target. |
If you know only the produce and approximate weight, that is still enough to start. “Not sure” is a valid answer; it is better than inventing a bag size because the form looked lonely.
Capacity is not just weight
A 25 kg rating is not only about strength. It also depends on produce shape, filling method, transport handling and closure.
Onions and potatoes do not pack like smooth machine parts. They shift, press and create local stress points. The seam and closure must fit the actual handling process.
Plain vs printed bags
Plain bags are usually simpler to quote. Printed bags require extra confirmation:
- artwork;
- print colors;
- repeat area;
- minimum order quantity;
- proof approval;
- lead time;
- whether the print affects recyclability or market requirements.
For a first request, separate the functional bag from the branding question. Confirm the bag first, then print.

Frequently asked questions
What should I specify for produce mesh bags?
Material, bag dimensions, capacity, mesh construction, colour, closure type, label or print requirement, packing format, quantity and destination. Ventilation is the main reason mesh bags exist, but it is not the whole specification.
Why are mesh bags used for onions and garlic?
Produce such as onions and garlic needs air movement during storage and transport. Mesh bags help ventilation and visibility while keeping the pack unit easy to handle.
Is a 25 kg bag rating only about strength?
No. It also depends on produce shape, filling method, transport handling and closure. Onions and potatoes shift, press and create local stress points, so the seam and closure must fit the actual handling process.
Should I order plain or printed mesh bags first?
Separate the functional bag from the branding question on a first request. Printed bags need artwork, print colours, repeat area, minimum order quantity, proof approval and lead time. Confirm the bag first, then the print.
