Fiber based food packaging materials are more sustainable than plastic, but they set high demands for qualities such as hydrophobation and liquid resistance. Liquid resistance is one of the most important packaging board characteristics that is needed for all take-away food packages such as noodle cups, coffee mugs or hamburger boxes. Thanks to liquid resistance, consumers are able to keep their fingers clean and liquids and grease inside the food packages.
In addition, board should be easily printed on and converted into highly appealing packages with brilliant color reproduction. High-quality packages should not only protect the enclosed products, but also help promote brands in highly competitive markets – where every little detail counts. All this requires expertise in chemistry.
