Aluminum foil products are lightweight and have good performance. Many products on the market are used, and they are widely used in food storage, medical medicine, aerospace and many other fields. After the current mature technology is improved, it has more barrier properties on the original basis, which plays a role in food preservation. Although it has so many excellent characteristics, the following points should be paid attention to in the selection:
1. The thickness of the coating of aluminum foil products can give full play to the full characteristics of the aluminum foil coating. It is indispensable to form a protective coating on the surface of the product to fully exert its barrier properties, so that it can easily achieve the effect of storing food. In order to preserve freshness, when selecting, the thickness of the product coating must be checked to ensure that it meets the actual production and processing requirements.
2. The surface state of aluminum foil products. When selecting, the high-quality aluminum foil presents a state of bright color, uniform distribution, and no clustering. The visual effect is very comfortable, and the touch feels rich, and the surface is very smooth. These are the surface states realized by high-quality aluminum foil, so you can distinguish them well by looking at the surface state when selecting them.
