I. Standard background
Food contact materials and products (hereinafter referred to as food contact materials) are direct/indirect contact objects of food and food additives (hereinafter referred to as food). In the process of contact with food, its ingredients are inevitably transferred to food, and its safety is directly related to food safety. To protect human health, in recent years, China has gradually improved and formed a standard system for food contact materials, which is mainly composed of four parts: general standard (GB 4806.1), additive and product standard (GB 9685 and GB 4806 series), testing method (GB 31604 series and GB 5009 series) and general hygienic standard for production (GB 31603). Among them, the National Food Safety Standard General Hygiene Code for Food Contact Materials and Products Production (GB 31603-2015) is a good operation code for food contact materials. Starting from the production and management of food contact materials, it improves the quality control level of enterprises and ensures the quality and safety of products.

Ii. Main contents of the standard
National Food Safety Standard General Hygiene Code for The Production of Food Contact Materials and Products (GB 31603-2015) is a series of measures, methods and technical requirements throughout the whole process of food contact materials production to ensure product quality and safety. It makes provisions from 10 aspects, such as factory environment, plant, facilities and equipment, personnel, raw and auxiliary materials requirements, product safety control, management organization, inspection, product traceability and recall, document management and recording in the production process, forming a set of operational operation specifications to ensure that the final product meets the standard requirements.

Iii. Implementation significance of standards
The implementation of the National Food Safety Standard General Hygiene Code for The Production of Food Contact Materials and Products (GB 31603-2015) has made basic hygiene requirements and management guidelines from the production of food contact materials, raw and auxiliary materials procurement, processing, packaging, storage and transportation and other links of the site, facilities and personnel, etc. Do the food contact material production quality control, ensure the quality of the food contact material security, lower food contact material of the migration, to ensure the whole in the subsequent in food production, processing, transportation, marketing, edible all contact with the food in the life cycle of materials such as related to the food hygiene quality and safety.
