Guides for people who have to specify this stuff
Four numbers and two process names decide most of what a woven bag costs and whether it survives its job. These pages explain them the way a factory would, with the arithmetic shown, so you can check a quote — ours or anyone's — instead of taking it on trust.
How many grams should this bag be?
What gsm a job actually needs, why the tolerance band matters more than the number, and how filler can hit your gsm while making the fabric weaker.
Lamination or coating?
Two different processes that English calls almost the same thing and Chinese does not. How to tell them apart on a finished bag, and which of them we can evidence.
What a factory needs before it can quote
The full checklist, what each line changes about the price, and which four answers are enough to start.
The arithmetic behind the first of these is on the calculators page. What we cannot evidence is on what we do not do.
