The swap that looks close
a larger carton is the usual substitute for void fill on a repeat pack, and it is the wrong one. The better fix is often the next carton size down. Fill is the fix when the size is already the closest.
Packaging Wholesale lists Void fill separately because the jobs diverge as soon as the goods are on the bench.
What the right line actually does
Void fill on a repeat pack means the carton is still a little large for the goods.
Loose fill, paper void fill and Ecoflo corn-starch peanuts are the fill lists. Bubble is the cushion, not the fill.
If you have already mixed them
Filling a carton that could have been a smaller size is the cost you stop noticing.
TradePro at Packaging Wholesale, 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 Void fill you needed.
Open Void fill when you already know this line. Fill is a pack or a sack. Read the unit before you order one and expect a week. Packaging Wholesale will still dispatch an order placed by 3pm on the same day.
