摘要：Paper and cardboard are widely used as food packaging materials, frequently in forms adapted to direct contact with foodstuffs. Although the raw materials are natural substances such as wood, a number of chemicals, such as slimicides, bleaching agents, and inks, are used during the production process. The recycled fiber which is an important raw material in producing paper and cardboard is also subjected to extensive treatment involving the use of inks, adhesives, and so on. The aim of this paper is to review chemical analysis and toxicology studies of paper and cardboard used for food packaging. Chemicals originating from wood, recycled fiber, and additives are detected in virgin/recycled paper products. In several bacterial and cytological studies, more recycled than virgin paper products were found to exhibit toxicity.
