As the global population expands, the demand for food packaging is growing. Food packaging is now facing new challenges, such as dose solutions that make it easier to move. The market brings a lot of challenges and opportunities to the food packaging industry. What kind of packaging plan can be brilliant? USDA researchers have successfully developed a new biodegradable, edible food packaging plastic film using casein in milk, which also performs better than traditional plastic bags in preventing food from spoilage.
The manufacture of degradable Food Packaging with Milk protein
The USDA said the casein film had holes far smaller than traditional plastic bags, so it was more effective in inhibiting oxygen penetration and was nearly 500 times better.
In addition to effectively preventing food from spoilage, the casein wrapper can be eaten directly and biodegradable when discarded outdoors. "Protein-based films are powerful oxygen blockers," researcher Peggy Tomasula said. "to make the material more durable, researchers added citrus pectin to casein. Researchers wrapped casein in a protective outer layer to keep it dry and clean. The U.S. Food and Drug Administration (FDA) has banned the use of three perfluorinated compounds (PFCs) in food packaging materials that researchers believe are a safe alternative to traditional plastic food bags.
environmental impact of food exposure. This means they can directly provide information about the quality of the product. Packaging with time-temperature indicators clearly indicates the precise freshness of the product, even after the shelf life. The technology also reliably indicates whether the cold chain process has been interrupted, Beijing Forum on the Development of aseptic Packaging Industry, a new type of "smart label" has received wide attention. The "smart label" using nanotechnology is attached to the outer packaging of the commodity. By changing the color from green to red, the quality can be directly identified as fresh or bad.
Packaging environmental protection: sustainable packaging materials will become the mainstream
Intelligent packaging is the new performance of food packaging given by scientific and technological progress, and it also solves the demand of consumers who want to understand the quality of goods more intuitively. In addition, from the perspective of the social development environment, green environmental protection is a major trend. The food packaging industry is no exception. One such example is the use of whey protein instead of petrified polymers as barrier materials for multilayer transparent film packaging. The whey protein layer is biodegradable. And the material that makes up the unseparable part of the whey can extend the shelf life of the food in a natural way. With only a few adaptations, the film can be produced by traditional machinery. Researchers are working on the application of whey protein film materials in the manufacture of thermoforming containers, such as cups or bowls. In addition, Carlsberg has developed pollution-free packaging bottles made from sustainable wood. Even the bottle cap uses this material, supplemented by biotechnology, to achieve the packaging of 100% biodegradable.
Packaging lightweight: reduce cost, easy to carry
It is worth noting that lightweight is also a major trend in the development of food packaging. In recent years, whether it is mineral water brands, snack food, wine, or beverages, dairy products, lightweight, Small packaging is the common demand of consumers and food enterprises. On the one hand, food enterprises hope to reduce the consumption of resources in the process of commodity production and the cost of commodity transportation through lightweight packaging. On the other hand, Consumers are also more keen on the convenience and waste avoidance of small packaged foods. Especially with the rise of young consumer groups, the trend of lightweight packaging will be more obvious. The change of population structure is also an important cause of food packaging lightweight. Judging from China's national conditions, the family of three will be the mainstream in the future, and lightweight small packaging will be more favored by this kind of people.
Packaging initiative: food safety is more secure
Food safety is a factor that can't be bypassed by packaging schemes. Packaging can protect food from external effects, such as microbial bacterial transfer, pressure loss, dust or moisture, thereby prolonging the shelf life. The role of safeguarding product quality. But so far, such protection has been done only passively. Modern packaging needs to be "proactive" in terms of "active" participation in physical-biological-chemical processes, Regulate the humidity of the packaging, absorb oxygen, carbon dioxide or ethylene and thereby extend the shelf life and quality of the food. But most importantly, they are bioactive, Packaging, as an essential part of food on sale, plays an important role. As people pay more attention to food health and safety, food additives are always worrying. The desire to find a solution from packaging is becoming stronger. Therefore, I am optimistic about the overall market of food packaging.
