The recipe of vacuum bag used repeatedly

摘要

The present invention relates to a method of manufacturing a vacuum bag that is repeatedly used by spraying a bio ceramic non-powder powder and a naphthalene alcohol solution on a nylon cloth, and immersing it in an immersion organic solution (silicone sealant solution and a latex solution) to treat highly airtight. Next, hot air-dried, airtightly treated two layers of nylon forge are fed to the feed roller, and the edges thereof are sealed with a sewing string with a sewing machine, and the immersion organic solution is sprayed and brushed on the sealing portion to seal the needle hole of the sealing portion, and After cutting automatically with the bag, it is transferred to the conveyor belt coldly, and the direction is changed at right angles by the pincer plate. The bottom part of the bag is sealed by sewing machine, and the handle hole is cut by the press cutter at the bottom of the bag. The sealing part of the bottom part of the bag while transferring to the Spray-sealed with an immersion organic solvent and dried with hot air to continuously manufacture the vacuum bag of the present invention, and the bag openings are tied with a string of elastic rubber vacuum plugs and exhausted using a vacuum pump. It was designed to continuously produce large quantities of vacuum bags that can be used for long-term storage of food, untie strings, take out the contents, and keep them in vacuum again and again.
