The difference between food grade kraft paper and ordinary kraft paper

All wood pulp production

Ordinary kraft paper will add some special ingredients in the manufacturing process, such as brighteners, fluorescent agents, etc., but food-grade kraft paper is not allowed to add any harmful ingredients that are harmful to the body. In addition, the recycled environmentally friendly kraft paper currently on the market is produced from recycled pulp, which has a wide range of sources and cannot control the quality itself. In addition, various chemical preparations and other harmful chemicals are added when the recycled pulp is deinked. No matter how the recycled pulp is treated, it is impossible to remove it, so it cannot meet the food-grade requirements that are harmless to the human body, so this type of kraft paper can only be used for ordinary packaging.
