Japan uses waste silk to make cling film

Japan Silkworm Insect Agricultural Technology Research Institute uses waste silk (can not reel silk and waste silk) processing made of plastic wrap.
The fresh-keeping material is characterized by high strength, resistance to stretching, moisture absorption and desorption through fruits and vegetables, adjustment of ambient temperature, better moisture retention in a dry environment, and can inhibit moisture evaporation of fruits and vegetables without drying up, and in a humid environment. It can maintain the proper temperature of the product and will not cause excessive moisture, so that the fruits and vegetables can reach the best state of freshness that is neither dry nor rot. According to the potato preservation test, it can achieve the same effect as the cold storage preservation.
The method for the preservation of waste silk is to pass the saggers and the waste silk through a process of boiling sorghum and alkali, to form a filament, cutting the silk fiber into silk pulp, and then processing it with a special half of the regenerated fiber.
