A3+ resealable cello bags for A3 artwork with mount board

320 x 440mm resealable cello bags (>A3)


A3 oversized cello bags are great for...

  • a number of A3 items
  • a thick A3 product
  • an A3 item with backing mount board
  • an A3 oversized item with a small frame

This is our larger than A3 cello bag. A3 is 297 x 420mm, so there is just over 20mm to accommodate the thickness of your A3 plus item/s. The flap with resealing strip is in addition to the 440mm length, so it will fold perfectly over your mounted artworks, prints, photographs, etc.

32 x 44cm (+ flap) archival quality, acid free cellophane bag in 40micron, crystal clear BOPP film.

The quality SEAL KING sealing strips are plain - no print after you tear away the liner.

Note, this size does not accommodate what is commonly referred to as "A3+" or "A3 plus" items. Although not part of the ISO International Paper Standard (and therefore may vary slightly between manufacturers), "A3+" is usually around 329 x 483mm.

packaging prints made easy

These larger bags are perfect for protecting small prints and also original watercolours in mounts. I packed 25 ready for the Margaret River Region Open Studios. Lynne Boladeras Art on Instagram: @lynneboladerasart
