Flexible packaging, unlike rigid packaging, has the ability to increase the product-to-package ratio, reducing overall waste from excess packaging and product that would have otherwise been left in the package.
With less material required in production and a resulting lower material weight in flexible packaging systems, this method of packaging results in less post-consumer solid waste. This means that after a consumer is done using the product and its packaging, there will be less of the package content to dispose of than, for example, glass or aluminum. In addition, a large portion of flexible packaging volume comes from corrugate, which is highly recyclable and is able to be reused, therefore reducing the amount of waste that ends up in landfills after use.*
Outside of this, flexible packaging helps to prolong the open shelf life of products. Since the package collapses on itself as the product is evacuated, air cannot enter the package and degrade the product quality.
