Can you transport acrylic paintings on canvas by rolling them and putting them in tubes?
When shipping canvases painted in acrylics, there are some considerations to address. First, lay down a sheet of thick mil Polyethylene plastic sheeting onto a clean table or floor. In the states, this plastic material is commonly found at shops, which cater to construction, and building needs, and usually is inexpensive and available in large rolls.

Secondly, lay the canvas face down onto the plastic. Next, carefully roll the canvas and plastic sheet onto a cardboard tube. Essentially, you want to use the largest diameter tube you can, and still fit the entire rolled canvas into another tube for shipping. Additionally, you want this to be compact, but do not roll the canvases too tight, as this runs the risk of the plastic sticking to the surface or causing a textural "ferro typing" to the surface of the artwork. For this reason, we don't advise to having bubble wrap used directly in contact with artwork. Polyethylene plastic should be between the artwork and whatever packing material is used. Essentially, shipping artwork where NOTHING physically touches the surface is ideal, however, many times this is impractical. The plastic should have an excellent resistance to adhering to the paint surfaces, which is why it's suggested. It's not for long term storage.

Also, don't rule out cracking of acrylic films. These are thermoplastic products, which means in warm temperatures they become soft and pliable and in cooler temperatures they are less tacky and more rigid. If flexed during cold temperatures you can crack an acrylic paint film. As these paintings arrive, allow them to come to room temperature before unrolling, and still, do this slowly and carefully.
