Board-back stock is the flat post. If that slot is empty, certificates get folded. This page stays with void fill beside the mailers.
Packaging Suppliers keeps Void fill apart from a larger mailer. Loose fill and paper fill take a gap in a box. A mailer that is too big should be a smaller mailer.
What this collects
Void fill belongs beside a carton, not inside a mailer that should have been a closer bag.
The notes below stay on void fill beside the mailers. Buying fill to plump a slack mailer fights the reason you chose a bag.
Before the order goes in
Use fill only on the carton side of the mailroom.
A Friday order on Packaging Suppliers that includes Void fill aims for Monday. A bank holiday on Friday or Monday moves that delivery. The 3pm cutoff is still the same-day dispatch rule.
