Detailed description
Most enquiries for this item come down to three decisions made in the wrong order: grade, width, then price. Grade sets the cycle life, width sets the roll cost, and the unit price is only comparable once the first two are fixed.
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
Do the peel test on the material you will actually bond to, not on a steel plate. The number in the specification is a reference value measured on steel; on powder coat or on a textile it will read differently, and that difference is the one your customer will notice.
If you are comparing suppliers, send the other quotes with the specifications attached and we will tell you which line item is the one that will move on the invoice.
