It also refers to the operations performed during the use of containers, materials, and auxiliary materials to achieve these objectives. For fragile or heavy packaging products, such as glass bottles, ceramic packaging, and tinplate cans, EPE, EPS, and EVA are commonly used as inner liners during transportation. These plastic liners provide excellent cushioning and protection, significantly reducing the risk of breakage. However, this approach neglects the environmentally friendly concept of "plastic reduction," leading to the frequent use of environmentally friendly paper liner packaging. Paper liner structures, made of paper or cardboard, offer advantages such as low cost, environmental friendliness, and recyclability, making them widely used in packaging for a wide range of products. Paper liners can be formed into a variety of shapes and structures through various design and processing techniques (such as folding, die-cutting, and gluing) to suit the packaging needs of different products.
