[Chinese Packaging Network News] Green Food vi Packaging design refers to the ecological environment without pollution, harmless to human health, can be recycled and recycled packaging. When people are very concerned about the ecological environment, the green packaging of food has become a necessity. According to experts' predictions, green food will dominate the world market in the next 10 years, while green food vi packaging design is the pass for green food among consumers. It has important implications for shaping green food brands. From the perspective of coordinating social development and ecological environmental protection, all countries in the world are reducing, reusing, recycling, and degrading as the goals and means of eco-friendly packaging.
With the joint efforts of Tsinghua University and the Institute of Microbiology, Chinese Academy of Sciences, the use of waste molasses as raw material to produce biodegradable plastic polyhydroxybutyrate (PHB), genetic engineering bacteria to produce biodegradable plastic PHB, and hydrolyzed starch as Production of biodegradable plastic PHB and its copolymer PHBV and modification and application of biodegradable plastic PHB. On this basis, it has achieved the first international scale production of the third-generation PHA hydroxybutyrate copolyhydroxyhexanoate (PHBHHx), a biodegradable material made from microorganisms, polyhydroxy fatty acids PHA, with excellent biodegradability, The compatibility, voltage and photoactivity, the diversity of its structure, and the new material properties resulting from structural changes make this material very promising for use in food packaging.
PSP, a German company, recently developed a new process for the production of foam paper. The packaging material it produces can replace foam. The foam was made of old newspapers and flour. The old newspapers were first cut into shreds, and then fibrous pulp was milled. The flour was mixed with flour in a ratio of 2 to 1. The mixed pulp was injected into the pressing pressure. Into cylindrical particles. During the extrusion process, the raw material is subjected to steam as a foam paper. Using this kind of foam paper as raw material, various shapes of plastic packaging can be produced according to different needs. Foam paper can be molded once, without chemical additives, and can be recycled after use.
The use of modern super-powder technology to crush raw materials into particles between 10 and 25 microns is called ultrafine powder. In recent years, it has been found that the preparation of starch-based biodegradable plastics using ultrafine powder technology has obvious advantages. The ultra-micro starch has small and uniform particle size, a large specific surface area, huge surface energy, significant improvement in fluidity and filling properties, and can effectively improve the mechanical properties of the material when used in the preparation of biodegradable plastics. Under the premise of guaranteeing the performance of materials, it can greatly increase the amount of starch added. This has important implications for reducing costs, saving petroleum resources, developing the application of natural starch, and increasing the biodegradability of plastics.
The U.S. Bureau of Agricultural Research Southern Regional Center uses soy protein, added enzymes, and other treatments to make soybean protein packaging films for food packaging that maintains good moisture, prevents oxygen from entering, cooks with food, and is easy to degrade and reduce the environment Pollution can also avoid secondary pollution of food. Indonesian scientists have invented the technique of making algae into cardboard. With two tons of dried algae, one ton of cardboard can be made. The quality of the finished cardboard is not inferior to ordinary cardboard. And has been commercialized production.
