PET fruit boxes realize scientific and efficient fruit fresh-keeping through structural design and material characteristics, solving the pain points of fruit mildew, water loss and oxidation deterioration during circulation. Firstly, the box lid is evenly distributed with precision micro ventilation holes, which form a stable air circulation system inside the container. It can timely discharge ethylene gas and excess water vapor produced by fruit respiration, avoid damp stagnation and bacterial reproduction, and effectively prevent mold and rot.
Secondly, PET material has excellent gas permeability balance, which can isolate external dust and bacteria while maintaining appropriate oxygen content inside the box, avoiding fruit anaerobic fermentation caused by fully sealed packaging. The smooth inner wall will not scratch fruit peels, preventing bacterial invasion from damaged parts. Some upgraded PET fruit boxes are matched with bionic antibacterial coating, which further inhibits microbial growth and slows down fruit oxidation and discoloration.
In cold chain transportation and normal temperature sales scenarios, the box body’s stable humidity control performance locks appropriate moisture, prevents fruit dehydration and shriveling, and maintains surface gloss and taste. Compared with ordinary plastic bags and cartons, PET fruit boxes extend the fresh-keeping cycle of berries and seasonal fruits by 30% to 50%. With scientific structural design and high-quality material performance, it provides reliable fresh-keeping protection for the whole process of fruit picking, transportation and retail.
