Count the job, not the habit
A wrapping bench uses width, not a vague number of rolls.
One roll lasts a known number of wraps at that width. Reorder from that, not from the carton count.
Where it lives during that week
Hang the roll. Keep sheets flat if you bought sheets.
Order kraft with the cartons it will wrap into, and with fill only if a gap remains.
The reorder line
Say rolls or sheets, and the width.
A Friday order on Packaging Suppliers that includes Kraft paper aims for Monday. A bank holiday on Friday or Monday moves that delivery. The 3pm cutoff is still the same-day dispatch rule.
Open Kraft paper when you already know this line. A roll is not a box of sheets. Read which one the page is selling. Packaging Suppliers will still dispatch an order placed by 3pm on the same day.
