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 ratio here is 40 percent nylon to 60 percent polyester. More polyester means a lower price, better width stability and better UV resistance, at the cost of some cycle life and colour depth. It suits outdoor covers, packaging and one-way applications more than it suits a closure the end user opens every day.
How it is quoted
Payment is 30 percent deposit with the balance against a copy of the bill of lading. Mixed widths on one purchase order are quoted as separate lines with a shared lead time, which is usually cheaper than splitting the order.
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.
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.
