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
The mistake in comparing quotes is looking at the width and the colour and ignoring the yarn. A 25 mm roll at 380 g/m2 and a 25 mm roll at 300 g/m2 look identical in a photograph and behave completely differently after five hundred cycles.
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.
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
Minimum order is 500 m in a stock colour and 3,000 m for a custom dye run. The dye minimum is a machine load, not a policy: below it the lot cannot be dyed evenly, and a split lot reads as two colours under D65.
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
Weigh a metre of the roll. Weight per metre is the fastest proxy for yarn density, and it is the number that shifts quietly when a supplier tries to hold a price through a yarn increase.
Send the grade, width and colour with the annual volume and the quote comes back against a real construction rather than a catalogue range.
