[Korean Farmers' News, Reporter Kim Young-min] The Topfresh Green Light storage film, known as breathable storage film for maintaining the freshness of agricultural products, has shown increased antimicrobial effects and storage capabilities through joint research with universities. Topfresh, established by the Dong-Oh Group with the aim of increasing the added value of agricultural products and the income of farmers by managing and maintaining the freshness of harvested agricultural products, manufactures Green Light, a storage film containing over 30% of the natural mineral illite in a proprietary composition. Green Light effectively adsorbs and removes harmful gases such as ethylene gas that occur during storage, and utilizes micro-pore technology.
