Count the job, not the habit
A week of soft lines can move to mailers and leave the carton shelf untouched.
Count the soft orders, not the whole dispatch.
Where it lives during that week
Keep mailers flat, by size. A mixed pile of sizes is how the wrong bag gets used.
Order mailers with a tape that suits polythene if the bag does not close itself. Do not add void fill for a bag that already fits.
The reorder line
Reorder the size that ran out. A larger bag is not a kinder fit.
On Wholesale Packaging, put Mailing bags 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 Mailing bags when you already know this line. Bags are pack quantities. Read the count on the product before you assume a single bag. Wholesale Packaging will still dispatch an order placed by 3pm on the same day.
