The Pros and Cons of Aluminum Bottle Cap Material
The application of aluminum in the packaging industry occupies the first place in non-ferrous metals. Aluminum plates are usually used as can-making materials or lid-making materials. Compared with other packaging material, what are the pros and cons of aluminum bottle cap material?
1. The density of aluminum is very small, 2.7 g/cm3, which is only 35% of steel. This makes the container easy to achieve lightweight.
2. Aluminum is non-toxic and tasteless, meeting the sanitary standards of food packaging and medicine packaging.
3. The aluminum has a high gloss surface and good coloring and printing performance.
4. The opening performance of the easy-open lid made of aluminum is better than the easy-open lid made of tin plate.
5. Aluminum has excellent light and heat reflection and conduction properties, which can improve the heat sterilization and low-temperature processing effect.
6. The mechanical properties of aluminum can remain unchanged at low temperatures, which is especially suitable for packaging frozen foods.
7. Aluminum scrap can be recycled and reused, which can not only save energy consumption but also prevent pollution caused by waste, and meet the requirements of environmental protection.
However, the aluminum cap closure materials also have some shortcomings:
1. Compared with tinplate and TFS, aluminum production consumes much more energy, so the price is relatively expensive.
2. Aluminum bottle cap materials have poor corrosion resistance and are not suitable for holding acidic, alkaline, and salt-rich foods.
3. Aluminum is soft and has lower strength than tinplate. It is prone to deformation and surface scratches due to collisions during manufacturing and transportation.
4. Aluminum is difficult to weld, so it can only be manufactured by stamping or bonding.
