The most commonly used material for packaging is plastic. Plastic is easy to make, but comes with a slew of environmental consequences, like long decomposition rates and damage to natural ecosystems. A great alternative to plastic packaging are metal containers made of tin and aluminum. These containers remove a lot of the issues created by plastic packaging. When metal containers are used for food and other perishables they often still require a plastic film, seal, or coating to completely protect the contents from coming into contact with air. In recent years biodegradable non-plastic packaging and films have begun to immerge as an alternative to standard plastic packaging. Biodegradable packaging is produced using biopolymers, which are molecules often found in living organisms, like cellulose and proteins. This means they can be safely consumed, degrade quickly, and often be created from waste plant products .
