The development of food packaging industry, with the enhancement of people's awareness of environmental protection, not only requires its appearance novel and beautiful, but also requires food packaging materials, easy to recycle, easy to decompose. Traditional packaging materials not only consume a lot of resources, but also pollute seriously, which is not conducive to. Therefore, the development of biological packaging materials has a very broad market prospects.

Biological packaging materials refer to the packaging application materials which use biotechnology and are related to organisms, or called bioengineering packaging materials.

As we all know, due to human production and living activities in nature abandoned a lot of plastic products that can not be naturally degraded, resulting in white pollution is one of the headache environmental and social problems encountered by countries in the world after industrialization. With people's attention to environmental protection and health, the demand of biological packaging materials in the field of packaging is growing, and manufacturers will also increase production capacity. It is expected that the market demand for biological packaging materials will continue to grow in the next few years.

Biological packaging materials can be decomposed by microorganisms in nature, which can greatly reduce the amount of garbage. About 41% of biological packaging is used for food preservation due to its good preservation effect. Since the 1990s, the global output of biodegradable materials has increased rapidly, of which about 60% is used in packaging industry. In 2011, the output of biological packaging reached 116000 tons, showing a gratifying trend of increasing year by year, with unlimited prospects.

Why biological packaging materials can achieve green is closely related to its processing methods and material selection. Biological packaging materials mainly include starch packaging materials, crop straw packaging materials, pulp molding packaging materials and so on.

Starch packaging is a hot spot in recent years, mainly developed in edible packaging. For example, starch itself emulsification can form a film, can be used in candy packaging. At present, this kind of film has been used in the packaging of vegetables, fruits, cakes and other food in developed countries such as the United States.

Crop straw packaging materials and starch are different, its main advantage is to turn agricultural residues into treasure. At present, a large number of agricultural waste straw has not been fully utilized in China, and this packaging material can realize the comprehensive utilization of agricultural resources and effectively alleviate the demand for wood in packaging industry. For example, the production of corn straw packaging materials is the combination of mechanical pulping and chemical prepreg; plant fiber packaging materials are made by crushing crop straw into plant fiber bundles, mixing with natural adhesives, and then through pressure filtration, injection molding and other processes. These packaging materials are in line with the concept of green in both production process and application effect.

Therefore, in the development of food packaging industry, biological packaging materials can be the top priority, and really take the green road, realize green development, reduce pollution problems. The relevant social associations take the lead in promoting green consumption and advocating the use of biodegradable materials. Production enterprises also adhere to the accumulation and develop more biological materials.
