Are these kraft mailer bags waterproof?

It’s hard to make paper waterproof, but these recyclable mailers can withstand a splash of water or light rain.

What are some common uses of the Expandable Kraft Mailer?

While Expandable Kraft Mailers can be the sole packaging layer for shipping, consider using them as a supportive solution. They are durable enough to ship soft goods such as clothes, backpacks, or solid items like books. But, their effectiveness is at an all-time high when wrapped around a corrugated box or another packaging item.

Do Expandable Mailers fit particular sizes of Mailer Boxes?

Yes, Expandable Kraft Mailer bags go perfectly with the sizes of our 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?

That’s not the case, unfortunately, but they do have a designated printing space on both sides in the centre. The size of the area for your graphics is dependent on your mailing bag’s size.

The exact outline of the printing area is visible on the diecut template. Make sure your artwork or logo does not cross the lines of the print space provided.
