Household Foil Roll for Food Packing
Food aluminum foil is a kind of thin metal aluminum products with a wide range of uses. It can be used for cooking utensils and food utensils, and is also a cleaning material.
The sealing effect of aluminum foil is particularly obvious. But if there are too many pinholes, it proves that the quality is poor, and the effect will be greatly reduced. Gas and light will penetrate directly and quickly, and the content will change quickly. Pinholes are related to thickness. The thinner the aluminum foil, the easier it is to form pinholes. For example, the number of pinholes of 7μm thick aluminum foil should be less than 210 holes per square meter: the number of pinholes of 9μm thick aluminum foil should be less than 90 per square meter. But we can guarantee that no matter how thick the aluminum foil is, the diameter of the pinhole will not be greater than 18μm. Therefore, we strictly control this. The aluminum foil we produce is strictly inspected and has a small number of pinholes. The oxygen permeability of aluminum foil is extremely low, effectively blocking the outside air. If you can't get in, the food will not spoil easily.
However, the aluminum foil itself is easily corroded. Therefore, food packaging bags are not simply made of aluminum foil, but are composited with other materials. Some are made of four layers of material. Many advantages are combined, which ensures that the bag is strong and durable. Our products are oil-free and dust-free, with high surface tension, reaching above 72mN/m.
The reason for using multi-layer composite materials is to package food and maintain food quality. Not only that, but this method is convenient for advertising on packaging and printing various exquisite foods. This is also a way for food to be recognized by the market and the only way for food to be promoted.
