Latest Patents

Koreasalo holds a patent for a "Method of making heat-sterilized product package". This invention centers around a polymer-coated heat-sealable packaging material designed for heat sterilization. The packaging material consists of a fiber base, potentially made from bleached pulp, and features polymer heat-seal layers on both sides. Unique elements include a first polymer coating layer containing white pigment to conceal the fiber base and a second coating layer with light-absorbing pigment. Additional innovations involve a grey pigmented coating inside the fiber base for light shielding and an absorbent black pigment outside the fiber base to enhance the material's brightness stability. This comprehensive design helps to prevent yellowing during the sterilization process, making it particularly suited for food packaging. The process is initiated by forming a package with the intended product and then heat-sterilizing the entire package in an autoclave.
