Detailed description
There is no single grade of hook and loop, only grades matched to a job. The material, the width and the put-up below are the three variables worth settling before the first order, because changing any of them later re-opens 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 construction is a woven hook and loop face in the standard grade: enough hook density for a normal closure, priced for volume rather than for a five-year service life. If the application cycles more than a few thousand times, ask for the higher-density weave instead of paying twice for the same part.
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
Peel and width are measured on the production lot, not on a sample kept from an earlier run. If your incoming inspection uses a different pull speed or dwell time, tell us and we will match it so the two numbers can be compared.
Checking it on arrival
Check the colour in the light the product is sold under. Warehouse fluorescent and daylight will disagree on dark greens and navies, and a lot rejected in one light is often accepted in the other. If it matters, agree the viewing condition before the order, not after.
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.
