The glass is made of silicate, alkaline substances such as sodium carbonate, calcium carbonate, and borax from a vacuum bag manufacturer, with auxiliary materials such as colorants. The vacuum bag is melted at high temperature. The ions inside the glass are united and intimate. After high-temperature smelting, the whole part constitutes insoluble salts and possesses excellent chemical inertness, does not create an effect with the packaged food, and possesses excellent packaging safety. Common glass is silicate glass. Soda lime glass, borosilicate glass, etc. The Egyptians first manufactured glass containers more than 3,000 years ago. Since then, glass has become a packaging material for food and other items. The vacuum bag is a kind of emotional material, has good chemical stability, and possesses bright and translucent colors. Because of its beauty, good barrier performance, recyclability and reuse, it is commonly used in the manufacture of food utensils (wine pockets, condiment bottles, etc.), vacuum bag containers, etc. The corrugated glass used for food communication is the soda-lime silica glass in the oxide glass, and the root causes of its safety problems are included. Dissolution of toxic substances in the smelting process. Poorly smelted glass products may create problems with the dissolution of audited substances from the raw materials of the glaze. Therefore, glass products should be soaked in water or heated with dilute acid. Foods with demanding packaging requirements. The medicine can be changed from soda lime glass to borosilicate glass. At the same time, attention should be paid to the quality of melting and molding process to ensure the safety of the packaged food.
