Additives have been critical to the growth of flexible packaging since its inception nearly 100 years ago. Additives help tailor the performance of new materials to meet packaging needs and to efficiently run on film converting and packaging equipment. Examples include antioxidants for thermo-oxidative stability during extrusion, slip and antiblock agents to improve film handling and frictional properties, polymer process aides (PPAs) to delay the onset of flow instabilities and increase output, pigments for coloring films and creating light barrier, antifog agents to improve wetting of film surfaces, antistat agents to reduce static charge, and nucleating agents for increasing the rate of crystallization and controlling crystalline morphology. This paper provides a brief history of the development and use of additives in flexible packaging, focusing on polyolefins. It then looks forward at new challenges and opportunities for additive development. One area is regulatory driven, most recently replacing per-and polyfluoroalkyl substances (PFAS)-containing PPAs with non-PFAS technology. The industry has had to respond very rapidly to changing regulations and introduce new technology. The challenge is understanding the impact of the new technology on performance. A second area is sustainability where additives will be critical for upgrading the performance of mechanically recycled post-consumer packaging waste, redesigning flexible packaging structures so that they can be recycled in the PE-stream, and using bio-based or compostable polymers. New research methods such as high throughput experimentation, artificial intelligence and computer modeling and simulation will likely accelerate additive development in the future.
Highlights
Additives are critical for meeting flexible packaging performance needs.
Additives improve surface and bulk properties and processability.

期刊介绍：
Journal of Vinyl and Additive Technology is a peer-reviewed technical publication for new work in the fields of polymer modifiers and additives, vinyl polymers and selected review papers. Over half of all papers in JVAT are based on technology of additives and modifiers for all classes of polymers: thermoset polymers and both condensation and addition thermoplastics. Papers on vinyl technology include PVC additives.
