Work out the answer yourself
Five calculations decide most of what a woven-bag quote actually costs. They are arithmetic, not opinion — so rather than publish a price range you cannot check, here they are with the working shown. Use them on our quotes and on everyone else's.
What the material costs
Dimensions, fabric weight and quantity in; the cost of the polypropylene and the plates out, per bag and for the order. It is for basic information only — a rough idea of the floor, not a quote. Many other factors affect the real price, and they are listed under the full page.
The rest of the arithmetic
What the material costs
Grams turned into money: resin and plates, per bag and per order, with everything the figure leaves out spelled out beside it.
Bag weight from geometry
What the polypropylene in a bag must weigh, before liner, print and handles — and how to tell a real quote from a padded one.
Fabric weight from the weave
GSM from tape denier and mesh count, in both directions. The formula used on the factory floor when nobody will tell you the fabric weight.
Check a quoted GSM
Weigh a sample, divide by its area, and see what fabric weight you were actually sold. A kitchen scale settles it.
What the printing plates add
Why a multi-colour job has a minimum order, what the plates add per bag at your quantity, and what a repeat run should cost.
