Check if the specifications for material pretreatment are well defined
Improve packaging processability
Some materials require specific conditions of storage before being transformed; the commercialization of new material is required to be able to provide the necessary technical information to future customers.
Avoid defaults of process due to unadapted preparation of materials before converting.
Materials containing undesired content of volatiles
Define the adapted heating pretreatment to desorb undesired volatiles
Materials containing undesired content of water, leading to material hydrolysis in process conditions
Define the procedure of drying and the condition of storage if the drying and process operations are not consecutive
Materials that need a minimum water content to allow transformability
Define storing conditions in a humid environment to reach adapted water content.
