In recent years, with the progress and development of modern science and technology, new types of packaging materials are emerging in an ever-changing and rapidly changing manner. All countries in the world are trying hard to research and develop a new generation of packaging materials to adapt to the trend of the times. Below to introduce several different functions of the new packaging materials. Anticorrosive paper for food packaging A Japanese company invented a new type of preservative paper for food packaging. The production method is that the base paper is immersed in an ethanol solution containing 2% of sodium succinate and 0.07% of sorbic acid, and the solution is dried after soaking. Packaging marinaded aquatic products with this preservative paper does not degrade at temperatures up to 38 ° C for 3 weeks.
