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.
With the liner-backed version, position the part before exposing the adhesive and roll it down with firm pressure. A peel test run twenty minutes after application reads low by design and should not be used to reject a lot.
How it is quoted
Widths are slit from the master roll in one millimetre steps between 10 mm and 150 mm, held to plus or minus 0.5 mm. A width that is not on the list is a slitting instruction, not a new tool, so it does not add lead time once the master exists.
What ships with the goods
Colour is checked against the retained standard under D65 on every lot, and weft skew, oil marks and hook damage are inspected across the full roll rather than on a cut sample.
Checking it on arrival
On arrival, measure the width at the core and at the outside of the roll before you cut anything. A roll that measures wide at one end and nominal at the other was slit under uneven tension, and the whole lot will behave the same way on your line.
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.
