A few days ago, the French company CristalUnion, the leading company in edible sugars, announced that the company will launch a sugar candy box made of sucrose, tailor-made for its brand, Daddy. There is no difference in the appearance of sugar-packed boxes and traditional chemical boxes that have been extracted from plants, but the cost has doubled. However, the new packaging can be recycled, which is very favorable to the environment. The environmental protection license will also attract a large number of consumers to purchase.
Ordinary packing straps provide convenience for everyone's life and also produce packaging waste. This not only increases the burden on the environment, but also increases the possibility of resource dross. With the rapid development of the food science and packaging industry, many new packaging materials and packaging methods continue to emerge. During this period, experts believe that edible environmental protection packaging materials will lead the sustainable development of the food packaging industry.
Edible packaging materials came into the mall and became the main theme of the society following the concept of low-carbon environmental protection. Many areas were identified, and packaging materials, including similar packaging and packaging areas, were the same. The rapid development of the food processing industry and the increasing need for packaging. It is understood that there are many kinds of green packaging materials on the market, which can be roughly divided into reusable and reusable packaging materials, edible packaging materials, degradable materials, and paper materials.
Reusable and reusable packaging materials are mainly used for packaging glass bottles for beer, beverages, etc., and can be used repeatedly; reusable packaging materials are mainly plastic packaging, and can be made into recycled packaging containers after being disposed of by physical means and disposed of after chemical treatment. Can be made into recycled packaging products. But these two methods are in the ointment and only reduce the pollution to the environment. In the end, they will also face the problem of polluting the environment.
The biodegradable data package can be degraded and restored on its own after use, and there is no pollution to the environment; paper packaging made of natural plant fibers is highly valuable for use and has sophisticated skills.
Edible packaging materials use natural edible substances (such as polysaccharides, proteins, etc.) as raw materials and constitute different edible packaging films through different molecular interactions. According to the selection of materials and processes are not the same, can be divided into polysaccharide edible packaging film, protein edible packaging film, composite edible packaging film.
The French green packaging box made of sucrose indicates that such packaging has been successfully developed and is now entering packaging malls, which will have greater use space and development prospects.
Edible packaging leads the sustainable development of the above industry. The relevant scientific research institutions and packaging companies have started to conduct research on the preparation and function of new edible packaging films.
In fact, many edible packagings have already been applied to real life in China. For example, wax, oil, gelatin, etc. applied to the surface of food and fruit can effectively reduce the loss of moisture and extend the shelf life. The glutinous rice cake covered with sugar and cakes is made of starch such as sweet potato, corn or wheat flour. The entrance is used to avoid sticking with the outer packaging; corn baking packaging and sausage casings of the ice cream cone are all typical edible packaging.
Over the years, sustainable packaging and green packaging have become a hot topic in the Chinese food packaging industry. Under the introspection of multiple factors such as retailer demand, public awareness, economic pressure (especially oil commodities) and government guidelines, sustainability has now penetrated into all aspects of food packaging.
