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 (+ 3cm 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.

440 x 320 30 micron cello bags

I received my order quickly and in good order.
I have not as yet used the bags, but the sample bag I received a few weeks ago was perfect for the use required, and am sure they are sturdy for my products

Great Bags

Bags are great quality. I got the A3 plus size as I was using them for A3 fine art prints with a foam board, but there is so much extra space, I should have gone the normal A3 for a snug, professional fit. Can't fault the bags though :)

Great product

We purchased the A3 size to wrap cakes for a school bake sale. They were perfect for our purpose and arrived very quickly after ordering. Highly recommend.

Christine McKenna (Sydney, AU)

I always buy my bags from Resealable Cello Bags. As usual I received quick and efficient service from the team and a well packed parcel arrived safely. These bags are good quality and perfect to package our smaller Auction prizes for the Angel Gowns Australia Fundraising Gala Dinner and online auction at the end of May. I definitely recommend this business.
