The protective function of packaging materials is that a product undergoes loading, unloading, transportation, storage, display, and other processes from the completion of packaging to the arrival of customers. There are many factors that can cause packaging damage at every stage. Packaging protection refers to the need to avoid damage during the logistics process that may cause loss of product quality and quantity, ensuring the smooth realization of product value and application value.

Packaging materials are the material basis of product packaging and the direct carrier of packaging functions. To achieve the protective function of packaging, it is necessary to choose appropriate ones. The packaging materials and containers made from it not only need to withstand various mechanical forces such as static pressure, impact, and oscillation during the cycling process, but also need to prevent external substances from oxidizing and corroding the contents, and avoid the contents from entering themselves.

Packaging materials are involved in achieving many convenient functions. For example, convenient opening and use require packaging materials to have appropriate mechanical functions. Convenient stacking and loading/unloading require packaging materials with strong tensile and compressive strength. Convenient processing includes packaging materials that can be recycled, reused, and easily differentiated. The research on green packaging materials is aimed at satisfying this function
