Tyvek?

Tyvek is a great material to use for packing, shipping, and storage purposes but the important thing to note here is that it is a very flexible material…while we do not see any potential issues happening between the Tyvek support itself and the acrylic paint here are some things to consider if you are choosing to paint on Tyvek if you want to promote the long-term preservation of your works:
1) Environmental fluctuations may cause ground and paint layers to expand and/or contract while not affecting the Tyvek support
2) Accidental creases and planar deformations (should they occur) are often impossible to rectify.
3) The Tyvek should be mounted on, or positioned against, a solid substrate, framed behind glass/glazing, and stored or displayed in a stable environment.
4) Tyvek is available in a range of different surfaces with some being more slick while others have a bit of tooth. Try to steer towards the latter, as the surface will provide more mechanical tooth for the paint to adhere to thereby avoiding the potential for flaking and delamination in the future.
