Is metal packing more advantageous than plastic packing?

Despite increasing consumer awareness of the materials used in packaging, there are still some issues and obstacles to moving from plastic beverage packaging to metal packaging. We will investigate the factors that use metals as substitutes to overcome these obstacles. For years, manufacturers have been looking for ways to reduce packaging to cut costs. Recently, however, much attention has been focused on changing packaging materials to help limit their impact on the environment and attract a growing number of consumers. A striking metallic material, aluminum, is the most common natural metal on earth. Aluminum production is an energy-intensive process, requiring about 14 kilowatt-hours (kWh) of electricity per ton of aluminum. The production process is far from green. But nearly 75 percent of the aluminum produced today is still in use, recovering only 5 percent of the initial energy consumption. In contrast, only 9 percent of plastic is recycled, and 79 percent of that plastic ends up in landfills or the natural environment. Aluminum packaging has an advantage over plastic packaging in that it is infinitely recyclable. Even if the plastic is recycled, it will eventually be incinerated or put in landfills. Unlike plastic, aluminum begins to degrade almost immediately after production, and it can maintain its quality indefinitely, no matter how many times it is recycled. As packaging, aluminum also provides the simplicity that plastics cannot be recycled. Aluminum is a material that consumers are largely aware of being recyclable. On the other hand, there are so many types of plastic that figuring out whether bottles, labels and caps have a recyclable variety doesn't encourage consumers
