A French Fries Box That Accelerates The Discharge Of Cold Air And Delays The Condensation Of Water Vapor
The core of the deliciousness of French fries lies in their crispy texture, and conventional packaging can easily cause the hot air released by freshly cooked fries to mix with cold air due to the sealed environment, forming condensation of water vapor and quickly softening the fries. To address this pain point, a French fries box has emerged that combines the functions of accelerating the discharge of cold air and delaying the condensation of water vapor. With a dual focus on structure and material, it locks in the best taste of French fries.
In terms of structural design, the French fries box adopts a dual system of "three-dimensional flow guidance+layered breathability". The top of the box body abandons the fully sealed design and adopts a combination structure of annular guide grooves and point shaped breathable holes: the annular guide groove is inclined along the edge of the box mouth to guide the cold air inside the box to be quickly discharged along the groove, avoiding the retention of cold air inside the box; Point shaped breathable holes are evenly distributed on the inside of the guide groove, with a diameter controlled at 0.8 millimeters, ensuring air circulation and preventing French fry chips from falling off. At the same time, three longitudinal ridges are set on the inner side of the box to create a 3mm gap between the French fries and the box wall, creating an air circulation channel to further accelerate the evacuation of cold air and reduce the space for water vapor attachment.
In terms of material selection, the box body is made of food grade waterproof laminated cardboard, with a composite nano hydrophobic coating on the inner layer. Waterproof film can block the infiltration of external environmental water vapor, while nano hydrophobic coating can reduce the adhesion rate of water vapor on the wall inside the box, allowing a small amount of condensed water vapor to quickly gather into water droplets and slide down the convex edges to the bottom guide groove of the box, avoiding contact with French fries. In addition, cardboard itself has a certain degree of breathability, which can assist in balancing the air pressure inside and outside the box, and improve the efficiency of cold air discharge with structural design.
This French fries box balances practicality and environmental friendliness, using biodegradable materials as a whole. The structural design does not require additional accessories, and the production and usage costs are controllable. After testing, the use of this packaging for French fries has been found to maintain their crispness for 40% longer at room temperature compared to conventional packaging, effectively solving the problem of taste loss during the transportation and consumption of French fries, and providing a convenient solution for optimizing the taste of the fast food industry.
