"Multilayer Body, And Package Using Same" in Patent Application Approval Process (USPTO 20240308187).

This patent application discusses a new type of multilayer body for food packaging bags that is designed to make it easier to open and remove the contents. The inventors propose using a combination of specific films and a sealant made from a polyolefin-based resin to achieve thermal stability and low resistance during opening. The multilayer body has specific orientation angles, piercing strength, and longitudinal orientation coefficient. The goal of this invention is to address the challenges of tearing packaging bags and preventing contamination during the opening process. The patent application also describes the specific materials and dimensions used to create the package, which is designed to be easy to open, have a step between the opening ends, and be adaptable to different shapes.
