Black poly mailer FAQs ▾
Black poly mailer FAQs
Can you see through black poly mailers?
No. Our black mailing satchels are fully opaque, so the contents are hidden. That makes them a good fit for high-value items and private orders.
How thick are your black mailing satchels?
They are made from 60 micron polyethylene with a strong self-seal strip, tough enough to resist tears and punctures in transit.
What size black satchel do I need for clothing?
As a guide: #01 (190 x 260mm) for a t-shirt, #02 (255 x 330mm) for a folded tee or leggings, #03 (310 x 405mm) for jeans or a hoodie, #04 (350 x 480mm) for a jacket, and #05W (430 x 545mm) or larger for bulky knits and multiple items.
Can I write on a black mailer?
Use a white shipping label or a white or silver paint marker. Our thermal shipping labels stick well to the smooth black surface.
Are black poly mailers waterproof?
Polyethylene film is water-resistant, so black satchels protect clothing and soft goods from rain on the doorstep.
Are these AusPost prepaid satchels?
No. These are plain courier satchels, so postage is not included. Send them with Australia Post or any courier and pay postage separately.
Do you sell black mailing satchels in bulk?
Yes. Packs range from 50 to 2,000 satchels depending on size, and larger packs cost less per satchel. Contact us for carton quantities or custom printing.
