Green environmental protection has become the general trend of the food packaging industry

In the food packaging industry, packaging is an important part of the food production process. It not only has the function of maintaining the quality of the food itself, but is also one of the key factors that express the appearance of the food and attract consumers. In recent years, as the environmental pollution problem of plastic packaging has become more and more serious, all parts of the world have unanimously emphasized the need to protect the environment and reduce pollution, and the packaging industry has begun to become environmentally friendly and green. Food packaging is divided into metal, plastic, glass, etc. according to the material, and bottled, sealed, and labeled according to the packaging method. It is understood that many production companies and scientific teams have developed innovative environmentally friendly packaging materials and containers to promote the development of green packaging trends.

Nowadays, environmentally-friendly pulp tableware, which is a green product, has gradually come into the eyes of the public. The materials used in environmentally-friendly pulp tableware are harmless to the human body. Once explained, there is no pollution during the manufacturing, use and destruction process, which fully meets the national food hygiene requirements. , And after the product is used up, it has the characteristics of easy recycling and easy disposal, which has attracted wide attention from inside and outside the industry. Environmentally friendly pulp tableware is a leapfrog revolution in the food packaging industry, and its future development prospects are very broad.

At present, there are not a few innovative packaging such as environmentally friendly pulp tableware. Many companies and scientific teams obtain packaging materials from nature to achieve green environmental protection. For example, the German Leaf Republic team uses leaves to make disposable tableware, which is not only waterproof and oil proof, but also completely degradable into fertilizer. It does not use any chemical products such as taxes or paint during the production process, which is completely natural. The foreign company Biome Bioplastics also looked for inspiration from leaves and used eucalyptus as a raw material to produce a bioplastic to replace traditional disposable paper cups. Cups made of eucalyptus can be fully recyclable and can also be used to make waste carton wood, which means that even if the eucalyptus paper cups are landfilled, they will not cause white pollution. There are also disposable plates made from leaves made by students in Wuhan, and biodegradable polymer-based biocomposite packaging materials made by Russian researchers using agricultural and forestry waste. A new direction.

In addition to obtaining raw materials for green packaging from nature, there are also many innovative methods for extracting required substances from existing foods for research and development. For example, German researchers invented a milk capsule that can be self-dissolved in hot beverages. This capsule uses sugar cubes, milk and condensed milk as the outer shell, which can be conveniently used in conferences, airplanes and other fast hot drinks supply places. Researchers have developed two kinds of milk capsules, sweet and slightly sweet, which can effectively reduce the plastic and paper packaging of milk and protect the ecological environment. Another example is Lactips, a French manufacturer of biodegradable thermoplastics, which also extracts milk protein from milk and develops degradable plastic packaging. The next step is to officially commercialize this type of plastic packaging.

All of the above are food packaging containers and flexible packaging, and a new sustainable material suitable for rigid packaging launched by Saudi Arabia has attracted the attention of the industry. The application areas of this material include containers, rigid packaging bottle caps and stoppers. It can be used for microwave heating to fill cups and bottles. At the same time, it can reduce the weight by reducing the thickness of the packaging. It has the dual advantages of environmental protection and light weight. Therefore, this type of material is very suitable for beverage production. In recent years, Coca-Cola has been working hard in the direction of light weight and green environmental protection, using PET to boost the content of recycled plastic in beverage bottles and convey the concept of green branding. Therefore, this innovative packaging material is undoubtedly a breakthrough development for the beverage industry.
