core tips: China's food packaging safety problems are serious, and data show that, In 2015, the EU notified 110 cases of food contact materials to China, twice that of Italy, the second place. In reality, there are a large number of materials used for food packaging, and there are many types of packaging materials in direct contact with food. Various chemical substances are in direct contact with food. Under certain conditions, the substances in food packaging materials will migrate to food, thus endangering food safety

[China Packaging News] China's food packaging safety problems are serious. According to the data, in the past 15 years, the EU notified 110 cases of food contact materials to China, twice that of Italy, the second

food packaging materials refer to the general term of materials used to manufacture food (food additives) packaging containers and constitute product packaging, also known as indirect food additives. Food packaging, on the one hand, is to avoid food damage in the later storage process and block the harmful substances that may enter the food, so as to protect food safety; On the other hand, it is convenient for food transportation and consumption

in reality, there are a large number of materials used for food packaging, and there are many types of packaging substances in direct contact with food. Various chemical substances are in direct contact with food. Under certain conditions, substances in food packaging materials will migrate to food, thus endangering food safety

according to the product notification issued by the European Union rapid food and feed early warning system (RASFF) in 2014, 152 cases of food contact materials were reported to China, accounting for 82.61% of the global notification (184 cases), an increase of 13% over the previous year. The food packaging safety situation in China is not optimistic

1. Types and factors of food packaging safety hazards

1.1. Plastic packaging and its hazards

plastic products have many advantages, such as light weight, convenient transportation, chemical stability, easy production, etc., and are widely used in food packaging. By adding a certain amount of antioxidants, preservatives and other auxiliary high molecular materials in plastics, it has a good protective effect on food. However, the surface of plastic packaging is prone to food pollution due to friction charged adsorption of micro dust impurities. The unpolymerized ethylene, ethylbenzene and other free monomers in plastic packaging will increase the risk of migration to food with the extension of contact time, resulting in food pollution. The stabilizers and plasticizers added to plastic packaging products have carcinogenicity and teratogenicity. The extensive use of plastic packaging increases the pressure of later recycling and pollutes the environment

1.2 paper packaging and its harm

in recent years, paper packaging has been widely used in food packaging because it can be made into bags, boxes, cans, boxes and other forms. However, since most of the raw materials of paper packaging come from the recycling of paper or paperboard, their bacteria, chemical residues and some impurities are often attached to the produced paper packaging, which increases the risk of food contamination by paper packaging. In addition, whitening agents and fluorescent chemicals used in most paper packaging are potential sources of food pollution

1.3 glass containers and their hazards

with people's demand for diversified and personalized packaging, many glass containers made of silicon dioxide are widely used in food packaging. In order to increase the gloss of glass containers, manufacturers often add arsenic, antimony and so on as clarifiers, and even lead. In addition, glass containers of various colors are also used as containers for food packaging. The prospect of using degradable plastics for food in garbage bags, plastic films, shopping bags, etc. is more promising because they are easily polluted by silica and other substances dissolved from glass

on the other hand, more and more metal, ceramic and rubber monomers are used as packaging, gasket and sealing materials in food packaging. If they are not handled properly, they will also cause potential harm

2. Reasons for food packaging safety hazards

the transportation and storage of food cannot be separated from the application of various packaging materials. The main reasons for packaging materials to endanger food are as follows

2.1 production link factors

the production enterprises of food packaging materials or containers have not done a good job in quality control in the production process, and the production raw materials used contain toxic and harmful waste materials. Some enterprises use packaging materials that have hidden food safety hazards due to their backward application technology in production and printing and non-standard quality management

2.2 use link factors

the use of food packaging materials pays more and more attention to sensory effects. Enterprises pursue the appearance of packaging materials or excessively pursue practicality, while ignoring the safety functions and health standards of food packaging materials. In addition, there are problems in people's use methods, which increases the food safety risk

2.3 management link factors

in recent years, relevant departments have increased safety supervision in the field of food safety packaging, and also successively issued a series of standards and rules. However, with the introduction of new materials and new raw materials, lax supervision and lagging standards exist to varying degrees, which also increases food safety risks
