Abstract

A 3D shaped packaging product () for cushioning and/or thermal insulation of packaged goods is formed by hot pressing at an average pressure equal to or below 200 kPa of an air-laid blank () comprising natural fibers at a concentration of at least 70% by weight of the air-laid blank () and a thermoplastic polymer binder at a concentration selected within an interval of from 4 up to 30% by weight of the air-laid blank (). The 3D shaped packaging product () has a density that is less than four times a density of the air-laid blank () and the density of the 3D shaped packaging product () is selected within an interval of from 15 to 240 kg/m. The 3D shaped packaging product () maintains at least a significant portion of the porosity of the air-laid blank () even after hot pressing and therefore provides excellent shock absorbing and damping properties and thermal insulation.
