Aluminum foil and aluminum plated film are widely used in daily life, but many people often confuse the two. Aluminum foil is an ultra-thin metal product made by rolling aluminum billets, commonly used in packaging, cooking, and other fields; Aluminum plated film is a layer of aluminum film covering plastic film, which is commonly used for packaging, preservation, insulation, and other purposes. This article will provide a detailed introduction to the differences and identification methods between aluminum foil and aluminum plated film, helping readers better recognize and apply them.
Aluminum foil is a pure aluminum product with good thermal and electrical conductivity, so it is often used to wrap ingredients or cover food surfaces during cooking. Aluminum foil has a smooth surface, thin and soft texture, and a certain tensile strength. When in use, aluminum foil can be folded and wrapped around food, and can also withstand direct heating from flames. When purchasing aluminum foil in supermarkets or daily life, its authenticity can be determined by touching the surface, conducting tensile tests, and other methods.
True aluminum foil has a soft and elastic feel, while inferior products have a hard and fragile texture. In addition, aluminum foil can be melted by fire, and real aluminum foil will emit the unique odor of aluminum.
Aluminum plated film is a layer of aluminum film coated on one side of plastic film, mainly used in the packaging industry. Aluminum plated film does not have the flexibility and tensile strength of aluminum foil, and is usually used for packaging food, medicine, or as insulation material. One of the methods to distinguish between aluminum foil and aluminum plated film is through texture and hand feel.
The surface of aluminum plated film is smoother and feels smoother than aluminum foil, and has a certain degree of ductility, but it does not have the thin and soft feel of aluminum foil. In addition, aluminum plated film can be tested for transparency under light. Genuine aluminum foil has strong transparency, while aluminum plated film is relatively poor.
Overall, aluminum foil and aluminum plated film have significant differences in appearance and usage. By observing their hand feel, texture, transparency, and other aspects, their authenticity can be distinguished. When purchasing and using, it is recommended to choose suitable materials according to actual needs to ensure the expected effect is achieved.
