Detailed description
If the last shipment had edges fraying, a width that measured wide on arrival, or a peel that read low in incoming inspection, the cause is almost always in one of the four items described on this page rather than in the price.
What the buyer is choosing
Two things decide whether a roll suits an automated line: the width tolerance at the core and the outside of the roll, and whether the put-up is splice-free. Ask for both in writing. A supplier who quotes a tolerance only for the finished carton is quoting the wrong measurement.
The material question
The fibre is nylon (polyamide). It takes dye deeply, which is why the colour range is wide and why the colour holds through washing at 40 degrees. Its weakness is moisture regain: a nylon roll absorbs water in transit, measures wide on arrival and settles back over about a week, so allow for it in incoming inspection rather than rejecting the lot.
How it is quoted
Samples ship in seven days, cut to the width you ask for, with the lot report from the run they came from. Bulk runs fifteen to twenty-five days after sample approval, EXW Xiamen, FOB or CIF as you prefer.
What ships with the goods
Each carton is marked with the lot number, width, colour and quantity, and the lot report references the same number. That is what makes a claim traceable six months later instead of a conversation about photographs.
Checking it on arrival
Open one carton from the middle of the pallet, not the top. Condensation and compression both show up in the middle of a stack, and the top carton is the one that was packed with the most care.
Ask for a sample at your width; it ships in seven days and it settles the substrate, colour and hand questions faster than any specification sheet.
