The differences between white card board and food card board

White card board refers to a single-layer or multi-layer combined paper that is completely manufactured using bleached chemical pulping and fully sized. It is suitable for printing and product packaging. Food-grade white card paper is the paper that comes into direct or indirect contact with food and must not contain fluorescent whitening agents or other harmful components to the human body. It is closely related to food safety and is often used as a material for food packaging. Ordinary white bull card paper has a high whiteness because it contains fluorescent whitening agents. At the same time, some special components are added to improve the performance of the white card paper. However, these special components can cause harm to human health. Therefore, ordinary white card paper cannot be used as food packaging paper. Secondly, the main uses of ordinary white card paper are to print business cards, certificates, invitations, covers, monthly calendars, and postal postcards, etc. While food card paper has a lower weight and is specifically used for packaging in the food field.
