Brasil Pack Trends 2020

BrasilPackTrends2020 79 package trends Smart packages monitor and give an indication of freshness and quality of food, as well as information that enable traceability and safety. This process includes detecting and reporting indicators, sensors and transmitters. These are examples of smart packages: time- temperature indicators; repining and freshness indicators; oxygen, ethylene, and CO 2 indicators; pathogenic microorganisms and toxins indicators; optimum temperature for consumption indicators; biosensors and nanosensors. The future of active and intelligent packages should be linked to developments to encourage interactivity, fun/entertainment and personalization of products. The package will empower the consumer to modify or optimize products, as well as to decide issues related to quality and freshness. Smaller and cheaper electronic components will favor the innovations.

These are highlights for the package area: nanocomposites (nanoclays and resins), carbon nanoparticles/nanotubes, oxides and metal at the nanoscale commercialized by manufacturers of resins and additives for packages. Nanotechnology applied to cellulosic and plastic packages can help to overcome their limitations, resulting in: • Improvement of properties: gas barrier, humidity barrier, UV radiation barrier, stiffness flexibility, heat resistance. • New features: antimicrobial package, oxygen absorbers, humidity absorbers, smart packages: sensors and indicators, self-cleaning surfaces, permanent antistatic surfaces.
