Moisture barrier film for food packaging
The granted patent (Publication Number: US11912488B2) discloses an article comprising a foodstuff and a package with a multilayer moisture barrier. The package includes a first outer layer, a second outer layer, and three inner layers with desiccant particles dispersed in a polymeric matrix. The desiccant, silica particles, helps maintain the desired moisture content within the package. The first and second inner layers are oriented layers made of specific polymers and contain a surfactant particle associated with the desiccant particles. Importantly, the third inner layer is devoid of desiccant, ensuring effective moisture control.
Furthermore, the patent details various claims related to the composition and configuration of the multilayer moisture barrier. These claims specify the percentage range of desiccant particles in the inner layers, the sealability of the first outer layer, and the absence of desiccant in certain layers. The patent emphasizes the nonmetallic nature of the layers in the moisture barrier and the package, highlighting the use of specific materials for effective moisture management. Additionally, it mentions the sorption properties of the desiccant, particularly fumed silica particles, and the composition of the polymeric matrix in the inner layers. Overall, the patent aims to protect a novel packaging design that ensures optimal moisture control for food products, enhancing their shelf life and quality.
