advantage

1. Excellent barrier properties Metal packaging containers can not only block gases such as air, oxygen, water vapor, carbon dioxide, etc., but also block light, especially block ultraviolet light, so it will not cause deliquescence, deterioration, corruption and fading of the contents and fragrance. Variety.

2. Excellent mechanical properties Because metal packaging containers are rigid and easy to operate, they can withstand collision, vibration and stacking, which is convenient for transportation and storage, and greatly increases the sales radius of goods.

3. Good thermal conductivity. The use of food metal cans has high heating and cooling efficiency, which can improve the effect of high-temperature sterilization and rapid cooling, and it is possible to achieve in-can cooking of the contents.

4. Good processing adaptability Due to the good ductility of metal, it can realize high-precision and high-speed production for complex forming processing. For example, the production speed of a tinplate three-piece can production line can reach 3600 cans/min. Such high productivity enables metal containers to meet the high demands of consumers at a lower cost.

5. Easy to use The metal packaging container is not easy to be damaged and easy to carry. Nowadays, many beverage and food cans are combined with easy-open lids, which increases the convenience of use, adapts to the fast-paced life of modern equipment, and is widely used in travel life.

6. Beautiful decoration Metal containers generally have a beautiful metallic luster, and together with colorful graphic printing, it adds to the aesthetics of the product. Because of this, when people give gifts, they often prefer products packaged in metal containers.

7. Hygiene and safety Due to the use of appropriate coatings, the metal containers can fully meet the hygiene and safety requirements of food containers.

8. Disposal and easy disposal Metal containers can generally be returned to the furnace for regeneration after they are used up and recycled. It not only recycles resources, saves energy, but also eliminates environmental pollution. Even if the metal is rusted and scattered in the soil, it will not have a bad impact on the environment.

9. Good shielding performance The protective packaging of high-tech electronic equipment can no longer stay on the basic protective functions such as moisture-proof, mildew-proof, rust-proof and shock-proof. When the electromagnetic wave penetrates the sensitive electrical components in the equipment, its effect is very similar to electrostatic discharge, which will make the electrical components fail and make the equipment unusable. The good shielding performance of the metal packaging container makes it anti-electromagnetic and effective in protecting high-tech electronic equipment.

10. With magnetic permeability The steel container has magnetic permeability, so it can be transported by magnetic force.

shortcoming

1. Poor chemical stability Under the action of acid, alkali, salt and humid air, it is easy to rust. This limits its scope of use to some extent. But now the use of various coatings with excellent properties makes up for this shortcoming.

2. The economy is poor, that is, the price is more expensive. This shortcoming is also being gradually improved through technological progress.
