Take you to understand the advantages and disadvantages of metal storage box containers

Metal material is a relatively traditional metal storage box material. For example, various instrument storage cans and beverage containers use metal materials. The use of metal packaging materials has a history of hundreds of years. With the development of modern technology, especially In the past few years, metal packaging materials have developed rapidly and have a wide variety of products. They are widely used in industrial product packaging, transportation packaging and sales packaging. Now metal storage boxes are used more in the field of composite materials, such as composite materials and plating using aluminum foil as the base material. Metal composite films have been widely used. Generally speaking, metal storage boxes have the following performance characteristics.

Advantages of metal storage box　　

1. Excellent barrier properties

   The metal storage box container can not only block gases such as air, oxygen, water vapor, carbon dioxide, etc., but also block light, especially ultraviolet light, so it will not cause deliquescent, deterioration, decay, fading, and fragrance changes of the contents.　　

2. Excellent mechanical properties

   Because the metal storage box container is rigid, easy to operate, can withstand collision, vibration and stacking, it is convenient for transportation and storage, and the sales radius of the product is greatly increased.　　

3. Good thermal conductivity

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

4. Good processing adaptability

 Because the metal storage box has good ductility, it can achieve high-precision and high-speed production for complex molding processing. For example, the production speed of the tinplate three-piece can production line can reach 3,600 cans/min. Such high productivity enables metal containers to meet a large number of consumer demands at a lower cost.　　

5. Easy to use

The metal storage box container is not easy to be damaged and is convenient to carry. Now many beverage and food cans are combined with easy-open lids, which increase the convenience of use to adapt to the fast-paced life of modern equipment and are widely used in travel life.　　

6. Beautiful decoration

The metal storage box container generally has a beautiful metallic luster, coupled with colorful graphic printing, which adds to the aesthetics of the product. Because of this, when giving gifts, people often prefer products packaged in metal containers.　　

7. Convenience and good hygiene.

The metal storage box container and the inner coating can generally meet the requirements of hygiene and safety, and the products packaged with it are easy to carry and use (generally equipped with easy-opening devices, such as the pull ring of a can), can adapt to different weather conditions, and are discarded It has good material handling properties and can be recycled and reused.

8. Friendly to the environment

The metal storage box container can generally be recycled and reused after being used up. It not only recovers 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. Has good shielding performance

 The protective packaging of high-tech electronic equipment can no longer stay on the basic protective functions of moisture, mildew, rust, and shock. When electromagnetic waves penetrate the sensitive electrical components in the equipment, their effect is very much like electrostatic discharge, which will cause the electrical components to fail and make the equipment unusable. The good shielding performance of the metal storage box container makes it anti-electromagnetic and effective protection of high-tech electronic equipment.　10. Magnetically permeable Steel containers are magnetically permeable, so they can be transported by magnetic force.　　

Disadvantages of metal storage boxes　　

1. Poor chemical stability

The metal storage box is prone to rust under the action of acid, alkali, salt and humid air. This limits its scope of use to a certain extent. But now the use of various coatings with excellent properties can make up for this shortcoming.　　

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