This standard specifies principles for uses of additives in food containers and packaging materials, the types of permissible additives, application scope, maximum level, specific migration limit or maximum permitted quantity as well as other restrictive requirements.
This standard is applicable to production, sale and users of all additives in food containers and packaging materials.
2 Terminologies and Definitions
The following terminologies and definitions are applicable to this standard.
2.1 Food containers and packaging materials
Those products made of paper, bamboo, wood, metals, porcelain, ceramics, plastics, rubber, natural fibres, synthetic fibres, glass and composite packaging materials that are use for packing and holding food; and coatings in contact with food; and the equipments, pipes, conveyor belts, containers, tools and utensils that are in contact with food during the production and sales of food.
2.2 Additives used for food containers and packaging materials
The additives are substances used during the production process of food containers and packaging materials intended to improve or assist to improve quality and characteristics; also include additives added during the production process of the food containers and packaging materials to assist the production process but not intended to improve the quality and characteristics of the final articles; for the ease of administration this standard includes also some monomers for polymers or polymerization starting materials that are used during the production process of food containers and packaging materials.
These are called Additives in this standard.
2.3 Maximum level
The total amount of additive allowed to be added during the processing of food containers and packaging materials, usually expressed as the portion of additives in the total base materials.
2.4 Maximum permitted quantity, QM
The maximum amount of additive permitted to remain in the food containers and packaging final articles, usually expressed in mg/kg or mg/dm2.
2.5 Specific migration limit, SML
The maximum limit of migration of additive from the food containers and packaging final articles to food or food simulants in contact with them, usually expressed in mg/kg or mg/dm2.
2.6 Chemical Abstract Service No., CAS No.
Chemical Abstract Service Numbers.
2.7 Not detectable, ND
Using applicable analysis method, the amount of additives in food containers and packaging final articles should not be detectable (DL).
