How does vacuum technology affect the sealing performance of aluminum foil packaging?

1. Improve sealing performance

Vacuum extraction technology reduces the gas pressure inside the aluminum foil packaging by removing the air inside the packaging, making the aluminum foil packaging fit the packaged items more closely. This tight fit helps prevent external air, moisture, etc. from penetrating into the packaging, thereby improving the sealing performance of the packaging.

2. Extend the shelf life

After the aluminum foil packaging is vacuumed, a relatively oxygen-free and dry environment is formed inside. This environment helps to inhibit the growth and reproduction of microorganisms, thereby extending the shelf life of the packaged items. Especially in the field of perishable and perishable foods such as food and medicine, vacuuming technology is of great significance for ensuring product quality and extending the shelf life.

3. Prevent oxidation and contamination

Vacuuming technology can also prevent the packaged items from reacting with oxygen in the air, causing oxidation and deterioration. At the same time, it can also reduce the moisture and impurities inside the packaging and reduce the risk of contamination. This is essential for maintaining the original quality and taste of the packaged items.

4. Enhance packaging strength

During the vacuuming process, the aluminum foil packaging will be subjected to a certain amount of pressure, which helps to enhance the strength and toughness of the packaging. When the packaging is subjected to external impact or extrusion, the stronger packaging can better protect the packaged items and prevent them from being damaged.

5. Operation steps and precautions

In actual operation, vacuuming aluminum foil packaging requires certain steps and precautions. First of all, it is necessary to select suitable aluminum foil packaging materials and vacuum machine equipment. Secondly, the vacuuming speed and time should be well controlled during the vacuuming process to avoid excessive stretching or damage to the packaging materials. Finally, after the vacuuming is completed, the packaging should be checked for tightness to ensure that there is no leakage or air residue.
