Food packaging bags can effectively change the expired fresh

Smart food packaging bags are designed to solve a common problem faced by many housewives: keeping track of food that's close to expiring or has already been opened. Eating such food might not be fresh, and throwing it away can lead to unnecessary waste. These "smart" packaging bags not only change color when the food is no longer safe to eat but also have a special "breathing" function that helps maintain freshness. The technology is expected to hit the market within the next two years. Professor Mills from the University of Strathclyde is leading the development of this innovative packaging. According to his team, if food like meat, fish, or vegetables goes beyond its shelf life or is left unrefrigerated for too long, its quality deteriorates. The smart bag will visually indicate this decline in freshness by changing color, reminding users to store food properly in the refrigerator. In addition, the technology aims to help consumers differentiate between the "best before" and "use by" dates, reducing the risk of foodborne illness. This could be especially useful for those who are unsure about whether food is still safe to eat. According to statistics, around one million cases of food poisoning occur annually in the UK. Professor Mills emphasized the importance of this innovation, stating that the goal is to reduce the risk of people consuming spoiled food and to make a meaningful impact on the meat and seafood industries. Experts from China Packaging Network believe that the development of such advanced packaging solutions plays a crucial role in ensuring food safety and improving consumer confidence. The introduction of these smart plastic bags could bring a new era of innovation to the Chinese packaging industry. These food packaging bags are not just practical—they’re a smart solution that everyone can appreciate. With growing concerns about food waste and safety, this technology represents a promising step forward in modern food storage.
