Food Packaging Material Standard
The basic elements of the framework structure of the food packaging material standard system include a total of six elements: safety, economy, environmental protection, product category, standard type, and standard level.
1 Safety elements
The factors affecting the quality and safety of food packaging containers and materials include 7 aspects: ① Heavy metals contained in packaging materials, such as lead and arsenic; ② Unpolymerized free monomers and their degradation products in plastic products, such as vinyl chloride monomers and phenols , Formaldehyde, etc.; ③ use prohibited additives and auxiliary agents in food packaging, such as fluorescent whitening agents; ④ use recycled materials, industrial raw materials to make food packaging, the introduction of unknown harmful substances; ⑤ various additives and processing aids Contains toxic and harmful substances; ⑥ harmful components in auxiliary packaging materials such as ink, adhesives, paints, etc., such as benzene residues, heavy metal residues, etc.; ⑦ inadequate hygiene control during processing, storage, and sales, causing pollution, such as microbial contamination, Heavy metal pollution, etc.
2 Economic factors
From the perspective of economic practicability, excessive packaging should be prevented, and the recyclability of food packaging containers and materials should be enhanced to save resources and prevent unnecessary waste.
3 Environmental protection elements
Not only must food packaging be good-looking and practical, environmental protection should also become an important factor for the food packaging industry to consider. On the one hand, packaging materials should be made of materials that do not pollute the environment; on the other hand, green products with environmental protection that can be folded and deformed should be used in packaging design.
4 Product category elements
Divided from the material, the standard system of food packaging materials mainly covers product categories such as plastic, paper, glass, ceramics, enamel, metal, wood, composite materials, auxiliary materials and so on.
5 Standard type elements
Any standard has its norms, constraints and defined scope. In the construction of the standard system of food packaging materials, the basic types of the standard system of food packaging materials should be divided within the framework of basic standards, safety limit standards, inspection and testing method standards, control management technical standards, label identification standards, product standards, etc.
6 Standard level elements
Standards with different scope of application should be in different positions within the framework of the food packaging material standard system. Various common standards should be at the highest level, and product-specific standards should be at a lower level, to achieve the purpose of reasonable simplification of the system composition. Common standards and product-specific standards together constitute a standard system framework for food packaging containers and materials.
