Mailing bags are the weekly outer for soft goods that do not need board. The page for Mailing bags is where Packaging Wholesale shows that line.

Grey mailers are opaque, recycled-film and described as recyclable. Coloured bags are on the same range.
A carton around a soft item adds board you post and store for no stiffness you needed.

The line is the bag size, grey or coloured.
At Packaging Wholesale, 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. You buy a pack of bags. The count is on the product. Packaging Wholesale will still dispatch an order placed by 3pm on the same day.
