It refers to various papers and boards used in food contact materials and articles, including waxed paper, silicone oil paper and pulp molded articles, which have been or are intended to be in contact with food or food additives (hereinafter referred to as food) or whose components may be transferred to food under normal conditions of use.
2.2 Pulp molded articles
It is a product with the pulp as major material and which is manufactured by processes such as shaping, molding, drying, etc. in accordance with the product purpose and required form.
3 Basic requirements
The paper and board used in food contact materials and articles shall meet the requirements of GB 4806.1.
4 Technical requirements
4.1 Requirements for raw materials
