I know this topic has been discussed earlier but I could not find the thread so I am selfishly starting the topic again.
I want to stack and put away my paintings in a box and wanted advice as to how to secure them well. For now each of the paintings are in a thin plastic cover (that the frames were individually packed in from the company) , followed by a bubble wrap cover and then in a cardboard box. I am worried whether keeping the plastic in contact with the painting is a bad idea in the long run and am confused between acid free tissue and silicone release papers (will the former stick to my painting and is the latter for long term storage, as i could not see "acid free" term in the description).
Thank you in advance.
