As a packaging material, the important feature of aluminum foil is its excellent barrier properties, which can effectively block air, water, and light, thereby maintaining or extending the shelf life and freshness of food. The characteristics of fresh-keeping, sealable, and full-scene heating make aluminum foil lunch boxes the preferred outer packaging for all kinds of pre-prepared dishes. The characteristics of high temperature resistance and internal and external coatings make it easy to handle the needs of microwave and open flame heating. A small lunch box looks simple on the surface, but it actually condenses a lot of hard work. It is endowed with multiple functions such as sealable, directly heatable, healthy and environmentally friendly, and recyclable, and there are countless technical adjustments behind it.
But what bothers Yue Xiubo the most is the curling process. If the curling is flawed, the sealing and pressure resistance of the lunch box will not meet the standards. Taking the "Internet celebrity" coffee capsule as an example, the production of this capsule requires aluminum foil materials with high ductility and high tensile strength. "Domestic aluminum foil manufacturers cannot make this material, and various parameters cannot meet the standards." He went on to explain that in order to overcome the problem, Times Aluminum Foil spent tens of millions to introduce advanced molds and material processing equipment. During the production process, technicians have to try to change the parameters and operation methods of the processing equipment one by one, just like "Shennong tastes hundreds of herbs", to achieve the optimization of the curling process.
As a national-level "little giant" enterprise specializing in new and innovative products, its dedicated attitude of being good at research enables it to constantly respond to new challenges. Aluminum foil lunch boxes are formed in one piece by high-precision molds, and the quality is often just "between microns". To accurately match the gap between the material and the mold to the micron level, new materials must be used. General materials only have one layer of aluminum base. In addition to the aluminum base, the new material of Times Aluminum Foil also has multiple layers of other special materials, which increases the elongation and compression resistance by 30%. "We have the independent design capability of the entire assembly line, including the research and development capability of equipment. Because we produce many types of aluminum foil lunch boxes, the requirements for equipment are also different." Yue Xiubo continued to introduce that the company currently has 120 patents and its products are exported to more than a dozen countries around the world, involving airlines, food packaging, baking and other fields.
