Food packaging box safety and production technology

Abstract: In recent years, there have been frequent cases of food safety issues, and many of them are caused by food packaging factors. Therefore, food packaging safety issues have become more and more serious.

It has received wide attention from food companies, society and people. Generally, the main factor that causes food packaging safety problems is the printing quality technology of packaging products. According to relevant data, many foods

The unqualified sanitary indicators of food products are all caused by the packaging, and varnish, film, ink, adhesives, etc. are the main pollution sources of food packaging. If you want to ensure the safety of food packaging

Therefore, it is necessary to further optimize and control its production process. This article mainly discusses food packaging safety and production technology.

    Food companies are paying more and more attention to food safety issues. There are many food safety issues, of which the safety issues of food packaging occupies a considerable part. To a certain extent, the quality of food packaging is directly related to whether the food hygiene indicators are qualified. In the current food safety sampling inspection situation, many of the failures in the inspection are due to packaging problems. Therefore, safe packaging and green packaging have become the current development trend of the food packaging industry, but they are also a major technical issue. problem. The following author will briefly talk about food packaging safety and production technology, hoping to help the packaging industry.

1. Food packaging requirements for printing inks

   Food packaging box materials will inevitably use ink and other spraying materials. Only with the use of ink can the food packaging box be differentiated and the packaging box will be more individual and distinctive. At the same time, printing ink is caused by food packaging safety issues. One of the most important sources. As far as the actual situation is concerned, although there are many categories of inks in the use of food packaging boxes, they are very different in terms of performance. Resin-based inks and solvent-based inks are mostly used in the printing of traditional food packaging boxes. Such inks contain a large amount of heavy metals and chemical solvents. Food packaging boxes using this type of ink are prone to heavy metal pollution and solvent pollution. Affect the hygiene and safety of food. Later, with the improvement of people’s requirements for quality of life and life, people’s awareness of health and environmental protection has gradually increased. In addition, the current concept of green packaging has gradually spread throughout the world, and more and more materials for printing food packaging boxes will be used. Green inks are put into trial use. The correct choice of printing process is the basis for ensuring the safety of food packaging boxes. For example, soybean ink is a new type of environmentally friendly ink. It uses soybean oil to replace the mineral oil used in traditional inks, thereby effectively reducing food and environmental pollution. Furthermore, in recent years, the flexographic printing process has gradually developed, and has been more and more widely used in the production of food packaging boxes.

2. Requirements for adhesives in paper food packaging boxes

  In food packaging cartons, adhesives are often used. Their role is mainly to bond corrugated mounts, cartons, cartons, handbags, laminating and coating, etc., which have a great impact on food packaging printing. Of course, the difference in composition leads to different effects of adhesives on food packaging and printing. If you want to reduce and avoid food contamination, you must use odorless, non-toxic, and benzene-free

Adhesive. Corrugated paper box mounting sometimes uses foam alkali as an adhesive, but because it is very easy to cause moisture regain in the carton, which will lead to food deterioration, this adhesive is generally

It is forbidden to be used in the production of food packaging. In addition, some adhesives contain benzene-based organic solvents, which can also threaten food safety, so they must be used with caution. If in the long run

Look, the food packaging production process is best to use water-based adhesives.

3. Requirements for varnishing oil on food packaging boxes

   Many foods are used in paper packaging boxes, and there must be some necessary printed graphics on the paper packaging, and in order to make the packaging better wear-resistant, moisture-proof and achieve a more beautiful effect In general, it is necessary to polish the surface printing of the packaging. However, some glazing oils are also likely to leave some organic matter on the surface of the packaging, which can easily lead to unqualified food packaging safety and quality. This is mainly due to the use of solvent-based varnishes in the production process of food packaging, which has higher wear resistance and brightness performance, but the disadvantage is that the solvent contains toluene, which is likely to cause food safety problems. Water-based varnishes, although their wear resistance and brightness performance are not as good as solvent-based varnishes, but because they are non-toxic, odorless, and non-volatile, they will not cause food safety problems, so they are more suitable for use. For food packaging. At present, many food packaging boxes are printed with water-based varnish.

4. Requirements for paper and cardboard for food packaging boxes

   Paper and cardboard are all materials that must be used in food packaging, and whether they meet the relevant standards is directly related to the safety of food packaging boxes. At present, European and American countries use food-specific packaging paper that does not contain fluorescent agents and harmful chemicals for video screen packaging. This type of packaging paper has many advantages, such as good anti-sticking, heat-resistant, waterproof and high barrier properties. And it has the advantage of being able to be used repeatedly, just wash it with water before each use, which is very convenient. Nowadays, this packaging production technology has been applied in the production and processing of many food packaging.

5. Requirements for film materials for food packaging boxes

   Film is used in food packaging such as cartons, cartons, flexible packaging, and fine corrugated boxes with windows. Therefore, the quality and safety of the film will also have a greater impact on the safety of food packaging, so this is also an issue. Ignored packaging safety factors. The film generally adds some low-molecular additives and auxiliaries, and under certain conditions, the film will produce chemical and physical migration of harmful substances, that is, the harmful substances inside the film are released, which seriously pollutes the food in the package. Therefore, non-toxic and odorless films should be used in the production of food packaging, and low-molecular-weight additives and auxiliaries must also comply with regulations, so as to ensure the safety of food packaging boxes.

6. Requirements for printing process of food packaging boxes

   In the printing of food packaging boxes, most of them are color printing, which requires the use of powder spraying technology, and the powder spraying produced by the powder spraying process in the production process is very easy to stick to the back of the packaging, and when food and packaging materials After contact, these powder sprays will contaminate food, especially liquid food, which will seriously affect the hygiene and safety of food. In addition, most inks have poor abrasion resistance and drying properties, so it is prone to overprinting in the process of printing inks, which will cause the ink to stick to the back of the package and then contaminate the food. Based on this, it is necessary to strictly control the powder spraying process and the selection of ink, and try to ensure that the printing is hygienic and clean.

7. The requirements of food packaging boxes on production machines

   The production machine is the basic hardware of production. In the process of printing, glazing, calendering and laminating of food packaging boxes, if the machine is not good, it may also cause contamination of the packaging. For example, if the machine is splashed with oil, some parts are dirty or the working condition is abnormal, etc., it may contaminate the printed product. Therefore, the factory must strictly manage the production machinery, maintain and maintain the machinery at ordinary times, and operate in strict accordance with the relevant norms and standards when using the machinery to prevent the food packaging boxes from being contaminated during processing.

8. Food packaging safety requirements for the production and operating environment

Regardless of the production process of food packaging boxes, a good working environment must be created first to ensure no dust, mosquitoes, and clean environment, so as to ensure the hygiene and safety of food packaging.

9. Conclusion

In summary, if you want to ensure the safety of food packaging boxes, you must strictly follow the food packaging box safety requirements for ink, adhesives, oiling, and paper and cardboard during the production and processing process. The requirements for the film materials, the requirements for the printing process, the requirements for the production machinery and the requirements for the production environment must not be sloppy.
