advantage
1. Excellent barrier performance metal packaging container can not only block gases such as air, oxygen, water vapor and carbon dioxide, but also block light, especially ultraviolet light. Therefore, it will not cause deliquescence, deterioration, corruption, fading and flavor change of the inner package.
2. Excellent mechanical properties because the metal packaging container is rigid, easy to operate, can withstand collision, vibration and stacking, 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 realize the in pot cooking of the contents.
4. Good processing adaptability. Due to good metal ductility, it can realize high-precision and high-speed production for complex forming processing. For example, the production speed of the tinplate three piece can production line can reach 3600 cans / min. This high productivity enables metal containers to meet a large number of consumer needs at a lower cost.
5. Easy to use, the metal packaging container is not easy to be damaged and easy to carry. At present, many beverage and food cans are combined with easy to open covers, which increases the convenience of use, so as to adapt to the fast-paced life of modern equipment and are widely used in tourism life.
6. Beautiful decoration. Metal containers generally have beautiful metal luster, coupled with colorful graphic printing, which adds to the beauty of goods. Because of this, when giving gifts, people often choose the goods packaged in metal containers first.
7. Health and safety due to the use of appropriate coatings, the metal containers fully meet the health and safety requirements of food containers.
8. Waste metal containers that are easy to treat can generally be recycled and recycled after use. It not only recovers resources and saves energy, but also eliminates environmental pollution. Even if the metal is scattered in the soil after corrosion, it will not have a bad impact on the environment.
9. With good shielding performance, the protective packaging of high-tech electronic equipment can no longer stay in 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 function is very similar to electrostatic discharge, which will make the electrical components invalid, resulting in the equipment being unusable. The good shielding performance of metal packaging container makes it have the function of anti electromagnetic and effective protection of high-tech electronic equipment.
10. Steel containers with magnetic conductivity have magnetic conductivity, so they can be transported by magnetic force.
shortcoming
1. Poor chemical stability. It is easy to rust under the action of acid, alkali, salt and humid air. This limits its scope of use to a certain extent. But now we use all kinds of coatings with excellent performance to make up for this shortcoming.
2. Poor economy means expensive price. This shortcoming is also being gradually improved through technological progress.
