UBE has developed an innovative oven-able polyamide (PA) designed for food packaging that can withstand high temperatures while ensuring food safety. The objective of this development was to create a material capable of resisting 200ºC for up to three hours, with an additional 10ºC safety margin for reliability.
The project focused on two types of polyamides: PA6 and CoPA. Both materials underwent extensive testing to ensure their thermal stability and performance in direct food contact applications. The films were extruded as 50-micron monolayer air-blown films, and different formulations were tested with heat-ressitant additives.
The PA6-based films (1030B) and CoPA-based films (5032B) were aged under controlled conditions in a dry oven at 200ºC for 1.5 and 3 hours, as well as at 210ºC for 1.5 hours, to assess their durability and resistance to thermal degradation. These tests confirmed that those PA grades containing those additives maintain their structural integrity and remain suitable for high-temperature applications.
This oven-resistant PA provides a breakthrough solution for food packaging, offering manufacturers solutions that ensures both durability and compliance with food safety regulations.
