Bubble padded envelope FAQs ▾
Bubble padded envelope FAQs
What is the difference between bubble mailers and padded envelopes?
They are the same thing. “Bubble mailer”, “padded envelope”, “bubble envelope” and “jiffy bag” all describe an envelope with a cushioning layer inside.
Which size padded envelope fits A4?
Size 03 (230 x 330mm) fits A4 sheets flat. Size 04 (235 x 350mm) gives extra room for thicker A4 items such as notebooks.
Which size fits A5?
Size 01 (160 x 230mm) fits A5 paper (148 x 210mm). For CD or DVD cases, the extra-wide DM (172 x 220mm) is a better fit.
Are poly bubble mailers waterproof?
Poly mailers are made from plastic film, so they are water-resistant and shrug off rain far better than paper mailers. Seal them fully for best results.
Do you have eco-friendly padded mailers?
Yes. Our honeycomb paper padded mailers use paper instead of plastic bubbles, and many of our poly bubble mailers include recycled (PCR) content.
Can I buy bubble mailers in bulk?
Yes. Most sizes come in packs of 25 to 200, and wholesale cartons of 500 to 5,000 bring the unit price down.
