Count the job, not the habit
A week of awkward shapes uses fill. A week of close-fit cartons should not.
Buy fill for the gaps you measured, not one bale per carton.
Where it lives during that week
Keep fill beside the bench, not in the carton store, or it will be forgotten until the carton is already closed.
Order fill with the cartons that do not fit, and with tape to close them. Fill is not a seal.
The reorder line
Say paper void fill, not simply paper, or the pick can become an 88 gsm kraft roll.
TradePro at Wholesale Packaging, for trade businesses, starts at 5% off and goes up to 10% when you spend over £1,000 a month, and it adds BACS. It does not change which Paper void fill you needed.
Open Paper void fill when you already know this line. The product page is the pack. A handful on the bench is not the unit you are buying. Wholesale Packaging will still dispatch an order placed by 3pm on the same day.
