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. The only resealable bag we have to fit "A3+" is our 410 x 570mm resealable cello bag. The 570mm length will fold over at 483mm but the excess in the width (81mm) would need to be folded over and stuck with tape for a snug fit.

Thanks Girls!

I love the products and the prompt delivery. As as a pencil artist I love how clear the product is so you can clearly see the images and detail on my products. I package my greeting cards, Tea Towels, Notebooks and Calendars in these cello bags and they make the product look good and be protected. Head to to see my products.
