The lines that belong together
Order grey mailers for the unbranded outer. PayPal branded bags are a separate range, in 250 x 350 mm, 305 x 405 mm and 425 x 600 mm.
Grey mailers sit with kraft tape or a polythene-suitable seal, not with void fill.
The line that stays separate
a padded envelope stays on its own order line. A padded envelope is the lined bag. A grey mailer does not add that cushion.
Mailing bags is the range Packaging Suppliers uses for grey mailing bags.
One basket
They are also called shoe bags. The category says they are European made from recycled film and 100% recyclable, and opaque so the contents are not visible.
At Packaging Suppliers, Mailing bags does not change the cutoff. Orders by 3pm leave the same day. Under £50 ex VAT the delivery is still available. It is just not the free threshold.
Open Mailing bags when you already know this line. Packs are the unit. Read how many bags are in the pack. Packaging Suppliers will still dispatch an order placed by 3pm on the same day.
