FAQ

Are these kraft mailer bags waterproof?

While not classified as waterproof, light rain is not a problem for these kraft mailing bags.

What are some common uses of Expandable Kraft Mailer

Expandable Kraft  Mailers can be used as a protective layer over an existing box, or, as well as a shipping solution on their own. Durable soft goods like clothes, backpacks, or solid items like books can be shipped in Expandable Kraft Mailing bags. However, they’re most effective if used alongside a corrugated box or another packaging item. 

Do Expandable Mailers fit particular sizes of Mailer Boxes?

Yes, Expandable Kraft Mailer bags are designed to fit our range of Mailer Boxes. Here are the specifications:

Y60 (250 x 350 mm) – F23 mailer boxes

Y80 (350 x 450 mm) – F23, F33, F44, F45, F52, F56, F59, F62, F65 mailer boxes

Y90 (400 x 500 mm) – F23, F33, F44, F45, F52, F59, F62, F65, F71 mailer boxes

Can you print on the entire space of an Expandable Kraft Mailer?

Unfortunately no. Each Expandable Kraft Mailer has a special space for your graphic design. This space depends on the size of the mailing bag you choose and it is centred on each side.

The die-cut template for each size shows the available print space. Remember that your graphic design should never cross the lines of the print space in the die-cut template.
