The universe of flexible lidding applications is large and continues to expand. Flexible lidding is used for packaging an enormous variety of foods, as well as medical items, pharmaceuticals, health, beauty and personal care products, hardware, small electronic parts and much more. While flexible lidding materials include film, paper and foil, in this primer we’ll take a look at flexible lidding film for food applications, an area we think will continue to grow in the near and long term.
Choosing a lidding film is a complex process. Today’s CPG has many considerations: the type of seal, seal strength, oxygen- and moisture-barrier and anti-fog requirements for the application. There’s also film thickness, the ability to seal through overfill, the type of container, the backing substrate, the ingredients inside the packaging, shelf life, sealing equipment, compliance requirements and the application conditions. All of these elements must be understood fully in order to ensure that the proper film is selected for a successful application.
