Development Overview And Performance Characteristics Of Metal Packaging
The metal packaging container is widely used because it has many unique advantages:
①Good mechanical properties. Compared with other packaging containers, such as plastic, glass, and paper containers, metal containers have higher strength, good rigidity, and are 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, gas barrier properties, moisture resistance, light shielding properties, and fragrance retention properties than any other materials. The seal is reliable and can effectively protect the product.
③It is easy to realize automatic production. The production of metal containers has a long history and mature craftsmanship. There are supporting production equipment and high production efficiency, which can meet the packaging needs of various products.
The disadvantages of metal cans cannot be ignored, such as:
① Poor chemical stability. Metal cans are prone to rust under the action of acid, alkali, salt and humid air, which limits its scope of use to a certain extent. Various coatings are now applied to metal packaging to make up for this shortcoming.
②The economy is poor, that is, the price is more expensive. This shortcoming is gradually being improved through technological progress. For example, the development of thinner metal cans in recent years is a good measure to reduce costs.
