Recently, a takeaway platform and the Chinese Academy of Sciences team launched a new silicone protective lunch box, which solves the problem of plastic pollution while ensuring food safety, attracting industry attention.


This lunch box adopts a multi-layer protection structure: the inner layer of polysilazane coating is resistant to high temperatures of up to 300°C, effectively isolating the migration of plasticizers; the middle layer of silicone resin forms a dense protective net, and the oil and penetration resistance is 5 times higher than that of traditional lunch boxes; the sealing part uses food-grade silicone rubber, which still maintains good air tightness after 10,000 opening and closing tests. Experiments show that it can be recycled more than 50 times, reducing the use of plastic by 80% compared with ordinary lunch boxes.


The head of the R&D team introduced that the new lunch box uses aerospace-grade silicone oil surface treatment technology, which not only maintains the anti-fouling and easy-to-clean characteristics of the lunch box, but also avoids the environmental burden brought by traditional fluorine coatings. At present, the product has passed the FDA food contact material certification, and the first batch of pilots have been put into Shanghai, Shenzhen and other cities. Users reported that the soup leakage rate has dropped by 92%.


As the "plastic ban" is further implemented, platforms such as Meituan and Ele.me are accelerating their environmentally friendly packaging replacement plans. Industry data shows that the market size of silicone packaging materials will increase by 217% year-on-year in 2023. New materials represented by silicone rubber tableware and silicone resin lunch boxes are reshaping the takeaway ecosystem. Experts predict that silicone materials are expected to replace 30% of takeaway plastic packaging in the next three years, providing key technical support for the industry's green transformation.
