The swap that looks close
vinyl tape is the usual substitute for buff packing tape, and it is the wrong one. Vinyl is the stronger film. It is not the default just because the buff roll ran out on a Thursday.
Packaging Wholesale lists Brown packing tape separately because the jobs diverge as soon as the goods are on the bench.
What the right line actually does
Buff packing tape is the repeat close for a brown carton on a weekly order.
Brown and buff tapes are listed apart from vinyl, clear tape and gummed paper tape.
If you have already mixed them
Swapping in vinyl for one week, then forgetting, leaves two tapes on the bench and no rule.
At Packaging Wholesale, Brown packing tape does not change the cutoff. Orders by 3pm leave the same day. Under £50 ex VAT the delivery is still available. It is just not the free threshold.
Open Brown packing tape when you already know this line. Check the rolls per carton on the product before you order one and expect a case. Packaging Wholesale will still dispatch an order placed by 3pm on the same day.
