Measure before you open the range
Choose vinyl for the cartons that failed with buff, not for the whole range.
Vinyl tape is the stronger film for a heavy seam or a carton that will be handled hard. The page for Vinyl tape is where Packaging Wholesale shows that line.
The published limit, if there is one
Vinyl and PVC tapes are their own list, not a colour of the buff tape.
Buff tape is the everyday close. Using vinyl on every light carton spends the strong tape on the wrong job.
Write the size down
Write vinyl, not strong tape, so the pick is the vinyl list.
On Packaging Wholesale, put Vinyl tape on the order with the lines it belongs to, so you are not paying a second delivery for the piece you forgot. Free UK delivery starts over £50 ex VAT.
Open Vinyl tape when you already know this line. The pack is rolls. Read the count. A single roll is a trial, not a week. Packaging Wholesale will still dispatch an order placed by 3pm on the same day.
