3.1Storage

HPL has to be stored at normal room climate, i. e. at approx. 18 – 25 °C and 50 – 65 % rel. humidity so that it is protected against moisture, humidity and direct sunlight. The sheets should lie flat on a suitable horizontal surface, e. g. on a pallet with a backing plate. The stack has to be weighted down with a cover plate. If HPL are supplied in film packaging, it is recommended to reclose the film and replace the cover plate each time after removing any sheets. If horizontal storage is not possible, it is recommended to store the material at an angle of approx. 80° with support over the entire area and a counterweight on the ground to prevent sliding.
