Detailed description
A buyer comparing three quotes for the same nominal product is usually comparing three different constructions. This page sets out what is actually in the tape so the quotes can be read side by side.
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
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
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.
Send the grade, width and colour with the annual volume and the quote comes back against a real construction rather than a catalogue range.
