E Wave (Micro Wave Cardboard)
This is a cardboard, where the corrugation height vary between 1,15 mm and 1,65 and which has 275-310 corrugations per metre. More corrugation per metre provides excellent surface strength. Although it is not used for the purpose carrying on its own, it becomes very good packaging material when it is combined with other waves. It is generally used for consumer nondurable goods and for packaging boxes for presents.
