Detailed description
The specification sheet for this item is short, which is exactly why it gets mis-bought. Two suppliers can both call a roll nylon hook and loop and still ship different yarn counts, different hook densities and a different put-up.
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
This is a nylon-polyester blend rather than a single fibre. The nylon share carries the cycle life and the colour depth; the polyester share carries dimensional stability and the price. Blends are quoted by ratio, so if the ratio is not stated, the two quotes you are comparing are not for the same product.
This one carries a pressure-sensitive backing, so the substrate decides the result more than the tape does: powder coat and acrylic hold, polypropylene and polyethylene have too little surface energy and will let go under load.
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
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
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.
Send the grade, width and colour with the annual volume and the quote comes back against a real construction rather than a catalogue range.
