Insulation cooler bags in daily life in a wide range of applications, in the picnic can be used in the lunch bag, if it is out camping, you can choose the trolley cooler bag, restaurants in the need to distribute meals can use the delivery bag, students go to school or work can choose to work with the lunch belt. Just mentioned only a small part of the ice bag application scenarios, there are many application scenarios will not be listed.
It can be imagined that the user in the choice of insulation cooler bag will be careful to choose the style that suits you. Then this article will give you popular science in the choice of insulation bag material is aluminum foil or aluminum film will be better.
Aluminum foil and aluminum film are two common aluminum film materials, they have some differences in structure and performance.
1. Structural difference:
Aluminum foil: Aluminum foil is a thin and flat sheet of metal made by rolling and stretching aluminum metal, with good toughness and plasticity, the common thickness of 0.006mm to 0.2mm.
Aluminum film: Aluminum film, on the other hand, is formed by the aluminum metal substrate surface of the film layer, the thickness is usually only a few nanometers to a few microns.
2. Difference in physical properties:
Aluminum foil: Aluminum foil has good barrier properties, can effectively prevent oxygen, water vapor and light penetration, while having good thermal conductivity and electrical conductivity. Aluminum foil also has certain high temperature resistance and oxidation resistance.
Aluminum film: Aluminum film, due to the characteristics of its thin film layer, usually has a higher transparency and optical reflection properties, is widely used in the optical field and electronic components.
3. Difference in the field of use:
Aluminum foil: Aluminum foil is often used in food packaging, pharmaceutical packaging, home decoration, electronic products shielding and other fields, used to protect products from external moisture, oxygen and ultraviolet radiation.
Aluminum film: Aluminum film is mainly used in the field of optical film coating, shooting lenses, battery electrode materials, etc., used to improve the optical properties or provide conductive function.
In summary, there are a number of differences between aluminum foil and aluminum film in terms of structure, properties and application areas. The specific choice of material depends on factors such as the required barrier properties, transparency, thermal conductivity, electrical conductivity and the environment in which they are used.
