From production and processing to transportation and sales, food contains many links, and each link has a risk of pollution. Therefore, food safety has always been the focus of consumers. With the rapid development of the food packaging industry and the continuous advancement of packaging technology, safe, green, intelligent and functional packaging has become an industry development trend, which not only guarantees food safety, but also solves environmental protection problems to a certain extent, bringing the food packaging industry into a New development period.
Safe packaging
Food packaging is gradually enriched with the advancement of science and technology and the rapid development of the food packaging industry. To a large extent, food packaging guarantees the quality and safety of food, extends the shelf life of food, and provides greater convenience for food storage and transportation. With the increasing awareness of food packaging safety, how to ensure the safety of food packaging has gradually become the focus of the industry. This requires industry professionals to work harder on food or meal safety packaging.
It is understood that in order to ensure the quality of food and temperature, some food and beverage companies have added double-layer packaging and aluminum foil foam to the take-out packaging, which not only keeps the heat, but also reduces external pollution and guarantees the quality of the take-out.
There are also the same methods used in meal packaging, with the addition of safety seals to achieve traceability of each dish. At the same time, a thermal insulation cover, alcohol cotton, and a security card are also added. As another example, a batch of edible sterilization paper has been developed abroad, which is mainly used for the long-term preservation of lo-flavored food.
Green packaging
With the rapid development of take-out catering, express delivery and other industries, a large number of take-away plastic packaging box garbage and express packaging bags have also become environmental protection problems. There are many types of garbage in this part, and the recycling cost is high and difficult to handle. Although takeaway catering companies and express delivery companies continue to introduce green packaging, compared with the surge in the total volume of takeaway plastic packaging boxes and express packaging bags, the scope of green packaging is "nine cows and one hair".
In the long run, it is the general trend of the industry to use green packaging materials, promote circular packaging, reduce excessive packaging and secondary packaging, reduce the use of excessive packaging and disposable products, and implement greening and reduction of food packaging materials.
In recent years, under the promotion of the national environmental protection concept, the food and takeaway packaging industry experienced early foaming lunch boxes and PP plastic tableware, and finally developed into degradable and recyclable environmentally friendly packaging materials to occupy the mainstream.
Smart packaging
From production to sales, food has to go through many links, and there is a risk of pollution in each link, so food safety has always been the focus of public attention. In the past, we could only understand the quality of a certain food through relevant tests. With the development of the smart packaging industry, the innovation of food labels, and the emergence of smart food labels, the production and processing of every food can be traced back , Food safety is no longer a problem.
As an important part of smart packaging, smart tags, that is, radio frequency identification, or radio frequency identification technology, use radio frequency to read and write recording media, so as to achieve the purpose of identification and data exchange. Smart tags have advantages such as applicability, efficiency, uniqueness, and simplicity. Among them, each RFID tag is unique, through RFID tags can clearly know the production, circulation and other conditions. Smart tags have been considered as one of the information technologies with great development potential in the 21st century.
Functional packaging
In recent years, people have paid more and more attention to packaging materials, and the requirements for packaging materials have become higher and higher, and their functions have become more and more abundant. In the field of packaging, functional packaging materials are developing rapidly, with a wide variety and promising application prospects. At present, functional packaging materials mainly have obvious high barrier, high strength, oxygen and water barrier, bacteriostasis, heat resistance, flame retardant, anti-static, aesthetic and biodegradation functions and so on.
Taking high barrier functional packaging materials as an example, barrier property is one of the important properties of food packaging bags. If the barrier of the food packaging bag is poor, it will change the taste and quality of the food, which will affect the quality of the product.
It is understood that the oxygen resistance of EVOH is significantly higher than that of any other material, about 10,000 times that of polyethylene. At the same time, the material can enhance the aesthetics of the product and improve the product grade while exerting the barrier performance.
With the increasing awareness of people's health and safety, green environmental protection, and the rapid blessing of the smart packaging industry, in the future, whether it is the food processing industry or the takeaway industry, product packaging will move toward safer, greener, smarter and more The direction of function development, green, safe and intelligent packaging may become the new favorite of the packaging industry.
