What is the difference between vacuum packaging and ordinary packaging?

There are significant differences between vacuum packaging and ordinary packaging. These differences are mainly reflected in packaging principles, packaging effects, applicable scenarios, costs and other aspects.

Ⅰ. Packaging principle

1. Vacuum packaging: Vacuum packaging is to extract all the air from the packaging container and seal it, so that the bag is in a highly decompressed state. The sparse air is equivalent to a hypoxic effect. Microorganisms need oxygen to survive. Vacuum packaging creates an environment where microorganisms cannot survive by removing oxygen, thereby achieving the purpose of preservation and antisepsis.

2. Ordinary packaging: Ordinary packaging does not remove the air in the package, but simply wraps or puts the product into a packaging container. Due to the presence of oxygen and other conditions required by microorganisms in the air, ordinary packaging cannot effectively inhibit the growth and reproduction of microorganisms.

Ⅱ. Packaging effect

1. Vacuum packaging: Vacuum packaging can significantly extend the shelf life of food, prevent food from oxidative deterioration, and maintain the color, aroma, and nutritional value of food. For electronic products, medical equipment and other products that need to be moisture-proof, dust-proof and oxidation-proof, vacuum packaging can also provide effective protection.

2. Ordinary packaging: Ordinary packaging has a relatively short shelf life and cannot effectively prevent food from oxidative deterioration or the growth and reproduction of microorganisms. For products that need to be moisture-proof, dust-proof, and oxidation-proof, the protective effect of ordinary packaging is limited.

Ⅲ. Applicable scenarios

1. Vacuum packaging: Vacuum packaging is widely used in the food industry, especially food that needs to be preserved or maintained for a long time. At the same time, vacuum packaging is also suitable for electronic products, medical equipment, textiles and other products that need to be moisture-proof, dust-proof, and anti-oxidation.

2. Ordinary packaging: Ordinary packaging is suitable for products that do not have high shelf life and quality requirements, or products that are used for a short period of time. For products that do not need to be moisture-proof, dust-proof, and oxidation-proof, ordinary packaging is sufficient to meet the needs.
