لماذا يتم استخدام رقائق الألومنيوم في التغليف؟

لماذا يتم استخدام رقائق الألومنيوم في التغليف؟? Because aluminum foil have good barrier properties. Aluminum foil can effectively insulate, and use it as a packaging material to protect items from damage due to high temperature. The common specification of aluminum foil for packaging is 7-15UM. In terms of packaging, aluminum foil has better barrier properties. It can inhibit the infiltration of oxygen and other inert gases within a certain period of time, which can better guarantee the shelf life of contents in the packaging.

Aluminum foil is an excellent packaging material. The shortcomings can only be related to its characteristics: it is light, thin and soft, and cannot be used for structural packaging. It is limited in tensile and shear resistance. وبالتالي رقائق ألمنيوم للتغليف must be combined with other materials to ensure packaging strength and ease of use. Aluminum foil has excellent properties such as poor air permeability (especially for oxygen and water vapor) and light-shielding, and also has the characteristics of shape retention and rigidity. وبالتالي, aluminum foil is used to package food as long as it prevents air from entering the food packaging bag. في الواقع, aluminum foil is a very good packaging material, especially in the field of soft packaging. This can be seen from the rapid development of the aluminum foil flexible packaging and aseptic package markets in recent years. الوقت الحاضر, milk with very high requirements for food preservation and quality and safety is used in aluminum foil composite packaging. Milk suppliers rely on aluminum foil composite soft packaging. The super strong effect of the bag on the milk is only able to rise. There are also aluminum foil packaging for small fish, beef jerky and other foods.

Now you know لماذا تستخدم رقائق الألومنيوم للتغليف, if you insist on the shortcomings, it is that aluminum foil used for packaging has to be compounded with other materials to achieve good results. Aluminum foil is generally used in packaging as a composite material.
