Multilayer packaging (MLP) plays a central role in the FMCG industry due to its superior protective properties and ability to extend product shelf life. This packaging technology combines the properties of a variety of materials to form a variety of functional layers, demonstrating excellent water and gas penetration resistance (such as oxygen and carbon dioxide), as well as strong mechanical strength and excellent low temperature resistance. These characteristics give MLPS a distinct advantage in protecting food and reducing food waste.
