Flexible packaging is one of the fast growing segments in the packaging industry. Defined as a package or any part of a package whose shape can be changed, flexible packaging can take the form of bags, pouches, liners and overwraps that come in a wide array of sizes.
Flex packages can be made from a variety of different materials. These materials include:
Flex pouches are made of multiple thin layers of high-grade materials including kraft and polyethylene. These multiple air-tight layers, along with a polyethylene barrier layer, provide a fantastic barrier protecting the packaged product from oxygen, contaminants and light, extending the shelf life of the enclosed products – even food. In fact, flexible packaging with a polyethylene inner layer offers the same amount of barrier protection as most plastic squeeze tubes.
