Dynamic compressive behavior of foamed polyethylene film
EPJ Web of Conferences, 2015 The foamed film as the shock absorption material has attracted much attention because it is thin (100 μm ∼ 400 μm) and has a closed cell structure. However, the dynamic mechanical properties have not been reported in the foamed film.
