Advances in film technology and new printing options are also prime contributors to this expansion. Environmentally conscious consumers are looking for packaging that uses fewer resources and less energy than other forms of packaging. Flexible packaging minimizes transport costs between the converter, packager/filler, retailer and end user. It not only takes up less space when empty than rigid packaging, but can also be formed on the spot from roll materials at the filling location, thereby minimizing transportation of ready-formed empty packaging. In addition to significant reductions in packaging costs, materials use and transport costs, flexible packaging provides certain performance advantages over rigid packaging.
As environmental pressures and high polymer prices drives the demand for thinner films, downgauging continues to be a key trend in flexible plastic packaging even though many of these films are reaching the limits of this trend. As downgauging reaches its limits, high-performance films are increasing in importance. These high-performance film structures provide advantages such as less permeability and increased shelf life, enhancing flavors in food products.
