When aluminum foil is applied to food packaging, it has the function of aroma preservation, color preservation, taste preservation, and quality preservation, which mainly depends on aluminum foil's high barrier, light resistance, high-temperature resistance, low-temperature resistance, oil resistance, water resistance, non-toxic and tasteless, and so on. Because of these nearly perfect characteristics and advantages, it is popular in the food packaging industry.

Let's take a look at the advantages of aluminum foil in food packaging.

1. High barrier, anti-oxidation, can extend the shelf life of food

The aluminum foil's high barrier properties, moisture resistance, and oxidation resistance can isolate food from oxygen, water vapor, stains, etc., creating an excellent storage environment for food. Some aluminum foil packaging also adds a desiccant/deoxidizer or uses vacuum packaging or vacuum packaging methods to achieve the purpose of extending the shelf life of food.

2.High mechanical strength, strong impact resistance, and penetrating ability

Aluminum foil has many excellent physical properties, such as high mechanical strength, impact resistance, strong penetration ability, making the food bag is not easy to break, can protect food from extrusion, impact, vibration, temperature difference, and other external factors and damage, to reduce the loss in the process of storage, transportation, putting frame.

3.Strong adaptability can adapt to a variety of environments

Aluminum foil has high-temperature resistance, low-temperature resistance, oil resistance, water-resistance and other characteristics, can adapt to a variety of environments, food processing and production environment on its performance does not have much impact.

4.Applicability is strong, can do all kinds of packaging

The aluminum foil is flexible and strong, suitable for various bag types and packaging, whether it is self-supporting, eight-side sealing, three-side sealing, four-side sealing...It is also suitable for different packaging methods such as vacuum and inflating, which has strong applicability.

5.Beautiful appearance, stimulating consumers' desire to buy

The printing performance of aluminum foil is suitable for the design of printing patterns according to the conditions of food packaging, and the use of beautiful appearance and design to stimulate consumers' consumption desire.

6.Green environmental protection, low cost

Aluminum foil is tasteless, non-toxic, green, clean and hygienic, which can ensure that it will not cause pollution to packaged food.In addition, its production of raw materials from a wide range of sources, compared to the traditional packaging, the production cost is lower.

The above are the advantages of aluminum foil used in food packaging!
