The patent application (Publication Number: US20240016700A1) describes an innovative induction seal for containers, comprising a mounting sheet and an induction seal liner with an active polymer component. The mounting sheet acts as a sacrificial panel of material, while the induction seal liner includes a multiphase polymer composition. The system also includes a backing panel and a semipermanent mount, with the semipermanent mount being a layer of wax or adhesive. Additionally, an extended-release coating can be added to the induction seal liner, and the active polymer component may include various agents such as desiccants, antioxidants, antimicrobial agents, odor-reducing agents, and anti-melanosic agents.

Furthermore, the system for controlling the chemical composition of a container's headspace involves an induction seal, a closure device, and a container receptacle. The induction seal liner is attached to the mounting sheet, with a mounting portion positioned between the liner and the sheet. The system also includes a lid fastening mechanism with male and female threading, and the semipermanent mount is destroyed when the seal liner is coupled to the rim of the container. The method for controlling the chemical composition within the container involves inserting the induction seal into the closure device, mounting it over the container's opening, and modifying the chemical composition within the container. The system aims to achieve homeostasis of compounds within the container after the seal is removed, with the mounting sheet serving as a seal until the material in the container is accessed by the user.
