The lines that belong together
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.
Mailers share a basket with padded envelopes only when some lines need a cushion and some do not.
The line that stays separate
a rigid carton stays on its own order line. A carton is for goods that must not be crushed. A mailer will not do that job.
Mailing bags is the range Wholesale Packaging uses for grey mailing bags.
One basket
The category calls them shoe bags or grey mailers. They are opaque, European made from a blend of recycled film, and described as 100% recyclable.
A Wholesale Packaging basket with Mailing bags still leaves the same day if it is placed by 3pm. The terms aim for 5.30pm the next working day. A 1 to 3 day courier is also described, depending on the lines.
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.
