What goes wrong
The usual waste is a clear roll on a brown carton, or brown tape on a white postal box.
Wholesale Packaging lists Brown packing tape for this line. Clear tape does the same close, and it shows as a stripe. Use it when the stripe does not matter.
The check before you reorder
Brown packing tape closes a brown carton when the seal should match the board.
Keep the live roll at the bench and the spare cartons of rolls above it, not in the box store.
Dispatch on that order
A Friday order on Wholesale Packaging that includes Brown packing tape aims for Monday. A bank holiday on Friday or Monday moves that delivery. The 3pm cutoff is still the same-day dispatch rule.
