GB/T 31479-2015 《Determination of colour fastness of dyed paper and board intended to come into contact with foodstuffs》 Related products

The GB/T 31479-2015 standard specifies two methods for determining the colour fastness of dyed paper and cardboard in contact with food. Method A is suitable for dyed paper and cardboard in contact with food for a long time (such as food Encasement paper), while Method B is suitable for dyed paper and cardboard in contact with food for a short time (such as napkins and kitchen paper). This standard aims to ensure that these materials do not migrate during contact with food, thus ensuring food safety.
