Advantages and disadvantages of metal box packaging

Because of its material characteristics, metal box packaging has better compression resistance than general packaging, is convenient for transportation, and is not easy to be damaged. Because of its strong oxidation resistance, various styles and exquisite printing, the metal boxes are popular among customers. Metal box packaging box refers to a thin-walled packaging container made of metal sheet. It is widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrument packaging, industrial product packaging, munitions packaging, etc.

At present, the United States and the European Union have a large demand for metal box packaging containers, and they have very promising development prospects. So, what are the advantages of metal packaging containers? What makes it widely used? The following are the advantages and disadvantages of the metal box packaging container that I have compiled for you, I hope it will be helpful to you!

1. Excellent barrier performance. The metal box packaging 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, corruption, fading and fragrance of the contents The change.

2. Excellent mechanical properties. Because the metal box packaging 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. Due to the good ductility of metal, high precision and high speed production can be achieved for complex forming 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 box packaging container is not easy to be damaged, and it 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. Beautifully decorated metal boxes generally have 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. Hygiene and safety Due to the use of appropriate coatings, the metal container fully meets the requirements of food containers for hygiene and safety.

8. Discarded and easy-to-dispose metal boxes can generally be recycled and reused after they are 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. With 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 packaging container makes it anti-electromagnetic and effective protection of high-tech electronic equipment.

10. Magnetically permeable steel container is magnetically permeable, so it can be transported by magnetic force. According to statistics, the reason why metal packaging containers are widely used is that they have many unique advantages.

①Good mechanical properties. Compared with other packaging containers, such as plastic, glass, and paper containers, the metal box container has higher strength, good rigidity, and is not easy to break. Not only can it be used for small sales packaging, but also the main container for large transport packaging.

②Excellent barrier properties. The metal sheet has better barrier properties than any other material, and has good gas barrier properties, moisture resistance, light shielding properties, and fragrance retention properties. In addition, the sealing is reliable and can reliably protect the product.

③It is easy to realize automatic production. The production history of metal containers has a long history, with mature technology and a complete set of production equipment, high production efficiency, and can meet the packaging needs of various products.

④ Exquisite decoration. The metal material has good printing performance; the pattern and trademark are bright and beautiful, and the produced packaging container is eye-catching, which is an excellent sales packaging.

⑤Various shapes. Metal containers can be made into various shapes according to different needs, such as round, oval, square, horseshoe, trapezoid, etc., which not only meets the packaging needs of different products, but also makes packaging containers more varied and promotes sales. However, metal packaging containers are not perfect, and there are some disadvantages.

Disadvantages of metal box packaging

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 a certain extent. But now the use of various coatings with excellent properties can make up for this shortcoming.

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