A high-performance bread preservation bag featuring extraordinary aroma retention and freshness-keeping capabilities. Its unique structure increases aroma retention by approximately 30% compared to conventional bags. It also prevents freezer burn and frost, keeping bread "moist, soft, and fluffy" even after thawing. Without using any chemicals, the advanced design reduces mold and bacteria growth to about 1/100th of standard plastic bags. Furthermore, bread can be packaged while still warm (approx. 50°C), significantly reducing cooling wait times. It is the ultimate solution for cafes and bakeries looking to minimize food loss, streamline operations, and add premium value to their takeout products.
