Put bag fabric and 600D polyester on base construction at 600D, 840D or 1680D ballistic and the decision mostly makes itself: abrasion through the coating at the trolley corners decides it, not the brochure.
The short answer on bag fabric
Choose bag fabric when lighter, cheaper, enough for retail bags. Choose 600d polyester when the priority is wears through at trolley corners within two seasons.
bag fabric against the alternatives, side by side
| Question | bag fabric | 600D polyester | Material | Bag fabric | 600D polyester | Where it wins | Lighter, cheaper, enough for retail bags | cheaper entry, simpler supply; measured on base construction, 600D, 840D or 1680D ballistic | Where it costs you | Wears through at trolley corners within two seasons | see the limits below | Typical MOQ | 800-1500 m per colour | often lower, because stock is common; held at base construction, 600D, 840D or 1680D ballistic | Lead time | 20-30 days | usually shorter for stock items; read against base construction, 600D, 840D or 1680D ballistic |

What bag fabric actually gives you
Base construction (600D / 840D / 1680D ballistic). Ballistic weave resists abrasion far better at the same weight.
Coating (PU 1-3 coats, 20-80 gsm total). Coating weight is the real water and abrasion story, not the base denier.
Abrasion (>= 25 000 Martindale).
That combination is why bag fabric holds the volume position in its category.
Where 600d polyester wins
600d polyester wins when the order sits below 800-1500 m per colour, when the service life is shorter than the warranty, or when the buyer is testing a market before committing. Paying for abrasion you cannot sell is as much a mistake as saving on a material that will come back.
Bag fabric: the cost of choosing wrong
The invisible one is the claim rate.
The reverse mistake is also common: specifying bag fabric for a product that will be replaced in eighteen months.

Questions buyers ask before ordering
Is 800-1500 m achievable at our volume on fabric vs 600d polyester?
On fabric vs 600d polyester, the working value for tolerance is 800-1500 m.
How do you verify tolerance against 800-1500 m on fabric vs 600d polyester?
On fabric vs 600d polyester, tolerance of 800-1500 m is what the line holds without special setup, which is why it is the standard quotation.
Does tolerance move between the fabric vs 600d polyester sample and bulk?
On fabric vs 600d polyester, below 800-1500 m on tolerance the failure mode changes from appearance to function, and visual inspection stops helping.
Bag fabric: the cost over the life of the product
| Cost item | bag fabric | 600D polyester | Who absorbs it | Unit price | higher | lower | Buyer, at the order | Claim rate | low if the spec matches the use; written as base construction 600D, 840D or 1680D ballistic | higher if the failure mode hits; measured on base construction, 600D, 840D or 1680D ballistic | Buyer, 6-18 months later | Replacement shipment | rare | likely once per programme; held at base construction, 600D, 840D or 1680D ballistic | Buyer, plus the lost season; read against base construction, 600D, 840D or 1680D ballistic | Customer relationship | protected | at risk | Buyer, permanently |

Bag fabric: a trial that costs one container, not a season
What bag fabric and 600d polyester have in common
abrasion, tear, weight applies to either, and the test that matters is the one that reproduces it.
bag fabric fails as crocking on dark shades; 600d polyester fails earlier and more visibly.
Many programmes use both: bag fabric where the specification is tight, 600d polyester in the range extensions where the price point matters more than the service life.
The other bag fabric comparison buyers ask about
Where bag fabric wins
The failure you are buying protection against is crocking on dark shades: black bag straps mark a white shirt. If that is the failure your customer will report, bag fabric is the cheaper decision even at a higher unit price.
How to decide without a trial order on bag fabric
Specifications for both are on the bag fabric page and the PU leather page.
Total cost over three years on bag fabric
| Line | bag fabric | PU leather | Note | Purchase | Higher unit price | Lower unit price | Paid at the order | Claims | Lower if the spec matches; written as base construction 600D, 840D or 1680D ballistic | Higher if the failure mode hits; measured on base construction, 600D, 840D or 1680D ballistic | Paid 6-18 months later | Replacement | Rare | Likely once | Paid in the season you cannot supply; held at base construction, 600D, 840D or 1680D ballistic | Rework at your factory | Lower | Higher if the material behaves differently; read against base construction, 600D, 840D or 1680D ballistic | Paid in labour |

bag fabric fails as crocking on dark shades; PU leather fails as hydrolysis.
A trial that answers the question in one container on bag fabric
How to test bag fabric against 600D polyester without a season of stock
The bag fabric versus 600D polyester question is usually settled by a trial order that was never designed to settle it. Four choices turn a bag fabric trial into evidence.
- Run bag fabric and 600D polyester on the same product, in the same colour, cut by the same operator — most comparisons of this pair are lost because the two samples were made a month apart.
- Fix base construction at 600D, 840D or 1680D ballistic and coating at PU, 20-80 gsm total on both sides, so the trial is about the material and not the specification.
- Inspect at in-process as well as pre-shipment: abrasion through the coating at the trolley corners is the failure that appears between the two on bag fabric, and a final check alone will not show it.
- Agree the decision line before the run: abrasion at 25 000 Martindale cycles or better, and coating at PU, 20-80 gsm total. A bag fabric trial without a written pass mark becomes an opinion.
One container is usually enough for a bag fabric decision if those four choices are fixed in advance, and the cost of the run is recovered the first time a lot is rejected at the destination instead of the factory.
Keep the bag fabric trial material. It is the reference for every later argument about whether the bag fabric base construction has drifted, and it is the cheapest document in the file.
The five-year cost of bag fabric against 600D polyester
On bag fabric, the purchase price is the smallest part of the five-year comparison against 600D polyester. Three bag fabric lines decide the rest, and only one of them is on the invoice.
- Purchase price. Usually 10-25 % apart, in favour of 600D polyester on a bag fabric comparison. That is a real number and it is the only line most buyers of bag fabric compare.
- Replacement rate. If bag fabric fails at abrasion through the coating at the trolley corners within two seasons, the replacement costs the whole purchase price again, and carries the same freight and duty.
- The cost of the complaint. A sorted bag fabric consignment, a credit note, a customer who now inspects everything — a line that never appears in a spreadsheet until it has happened.
The break-even on bag fabric is arithmetic once the replacement rate is known: if bag fabric replaces more than one lot in five, the cheaper option has already lost on base construction.
Which is why the trial above matters more than the quotation for bag fabric. It is the only way to put a number on the middle line, and coating at PU, 20-80 gsm total is the figure that number hangs on.
