Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to packaging cushioning liners. Background Technology

[0002] To prevent damage to fragile items such as displays during handling and transportation, polystyrene (EPS) cushioning materials adapted to the shape of the product are typically filled inside the packaging box. These cushioning materials fully fill the space between the product and the packaging box, ensuring the product is stably secured within the box and preventing slippage and collisions during handling and transportation, thus improving the safety of goods during transport. However, considering the stable nature of EPS and the fact that its combustion process produces harmful substances, the extensive use of EPS cushioning materials inside packaging boxes can easily cause environmental pollution. Furthermore, EPS cushioning materials are bulky and non-compressible, requiring significant space in the manufacturing and storage processes. Therefore, designing packaging liners that can tightly fill the space between the product and the packaging box to form cushioning, and which are recyclable, is of great importance for improving the safety of goods during transportation and reducing packaging costs.
