The packaging industry is the sector, which often requires different temperatures throughout the process, so it is necessary to use equipment that provides a flexible and efficient heat source. The most common materials used in this industry are plastic, glass, and paper containers. In packaging manufacturing process sometimes use a lot of live steam, which means a lot of water. This can result in high concentration cycles in the boiler and a quick increase of total dissolved solids, resulting in elevated amounts of boiler blowdown. So to operate efficiently, water quality is needed to be considered.
How are boilers used in Packaging Industry ?
Recycling: Steam for stripping Ammonia in the recovery process. Steam for separating oil and water mixtures, cleaning and disinfection of reusable bottles, or pelletizing waste wood.
Plastics: Steam for cleaning and sterilizing bottles and kegs. Hot water and steam for thermal drying processes. Steam for foaming of, for example, polystyrene and for forming processes.
Paper: Steam for thermal pulping and treatment processes. Steam for heating the cylinders. Steam for pressing, transporting and drying the paper rolls.
