Rigid mailer FAQs ▾
Rigid mailer FAQs
What is a rigid mailer?
A rigid mailer is a hard back envelope made from thick board, here 700gsm, so the contents stay flat in the post.
What size rigid mailer do I need for A4?
The A4 rigid mailer is 240 x 330mm, giving room around a 210 x 297mm A4 sheet.
Do you have rigid mailers for A3 posters?
Yes. The A3 rigid mailer is 330 x 450mm and fits A3 (297 x 420mm). For A2, see our eFlute A2 rigid mailer.
Rigid mailer or eFlute?
700gsm rigid mailers have a smooth white glossy finish. eFlute envelopes are corrugated, which makes them light and stiff, and they come in more sizes and colours.
Can I buy rigid mailers in bulk?
Yes. A4 and A3 rigid mailers are available in wholesale cartons of 500.
