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 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
Quotations are built from construction, width and colour, in that order. Change any one of the three and the price moves, which is why we ask for all three before quoting instead of sending a range and adjusting afterwards.
What ships with the goods
Certificates are issued per lot rather than per year, and REACH and RoHS declarations travel with the shipping documents. OEKO-TEX documentation is available on request for skin-contact applications.
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.
