Recently, according to the report of the UK Today China News Network, the world’s first non-plastic packaging supermarket successfully opened in Amsterdam, The Netherlands. All the products in the store are packaged with biomaterials. The so-called biological materials refer to the use of biotechnology and will be green. Or natural materials processed into packaging application materials.
Today, plastic packaging has become a major difficulty in protecting the ecological environment. This type of traditional packaging not only consumes large amounts of resources, but also exacerbates white pollution. The emergence of bio-packaging materials is just right for this. In some European countries, Started to use fat film, protein, etc. as a material for food packaging, such as a Danish brewery that is developing a wood fiber bottle, which uses greener packaging materials to achieve green degradation. Another example is the Netherlands is also working to produce the cost Lower, more environmentally friendly bio-based plastic packaging materials, and plans to achieve commercial use within two years. Visible, bio-packaging materials have a very broad prospects, the future will be applied to various fields.
Why bio-packaging materials can achieve environmental protection, which is closely related to its processing methods, material selection. Biological packaging materials mainly include starch packaging materials, crop straw packaging materials, pulp molding packaging materials, etc. Among them, starch packaging is in recent years The research hotspots in various countries are mainly developed in edible packaging. For example, starch itself can be emulsified to form a film and can be used in candy packaging. Currently, such films have been used by developed countries such as the United States in the packaging of vegetables, fruits, and pastries. in.
Crop straw packaging materials are different from starch, and its main advantage is to turn agricultural residues into treasure. At present, China's large amount of agricultural waste straw has not been fully utilized, and this packaging material can achieve comprehensive utilization of agricultural resources. And effectively reduce the packaging industry's demand for wood. For example, the production of corn straw packaging material is to combine mechanical refining with chemical pre-soaking; plant fiber packaging material is to smash crop straw into plant fiber bundles, mixed with natural adhesives. After the pressure filter, injection molding and other processes made, these packaging materials, whether it is the production process or application effects, are consistent with the concept of green environmental protection.
This can be seen in the reasons for the green environment of bio-packaging, but what is the reason for its rapid development? First, bio-packaging has many advantages, such as energy saving, environmental protection and recyclability, which is unmatched by traditional packaging. The second is the North American market. , Government and distribution channels are actively promoting the application of such new materials, making biomaterials a major trend in the industry. While China’s related manufacturing companies are adapting to trends, machinery manufacturing companies are also making full use of them. Plant fiber packaging materials need to be used in molding machines, filter presses and other equipment, machinery manufacturing companies have to win in performance and quality, manufacturing equipment and biotechnology matching products.
Not only in the food industry, bio-packaging materials are being actively promoted in other areas. For example, in the express delivery industry, the newly revised “Express Packing Supplies” clearly states that 'express packaging bags should adopt bio-degradable plastic' and strengthen the reduction. Requirements. However, if bio-degradable materials are used in the express delivery industry, the cost will increase, which makes many companies unwilling to adopt them. Moreover, the express delivery companies operate in a network-wide manner, and some of the packages are issued by the headquarters. To various express delivery sites, this poses a certain degree of difficulty for the supervision of the department. Therefore, in order to achieve greenness in express packaging, it is necessary to start from multiple links. The enterprise is only one aspect.
The road to green packaging for food packaging is just like the express delivery industry. All parties working together can really achieve green development and reduce pollution problems. For example, government departments take the lead in promoting green consumption and advocate the use of biodegradable materials. Production companies insist on active innovation and develop More biomaterials, or the application of such packaging materials in the production of products. Machinery manufacturing companies to provide production companies with better equipment, make the production process more efficient.
