The increase in the presence of plastic in our lives is an unstoppable trend due to the versatility of this material. So innovation in the packaging industry has been focusing on the development of new, more sustainable, economically viable materials with enhanced properties and which also perform the functions required by this sector: to contain, protect and preserve the product, to inform the consumer about it and to facilitate the distribution of it. Traditional containers protect the product and, what is more, are cheap and durable. However, their durability poses a serious problem for the environment, so work is being done to develop sustainable materials that are in line with the trends observed among manufacturers and consumers.
