This is a cushioning pad ideal for packaging, made from polyethylene film integrated with plant-derived biomass plastic and cardboard. By sandwiching the product between the film and the backing paper, it can be easily secured. Utilizing its stretchable properties, we propose a new packaging form. The material's stretch allows for packaging items of different sizes together. This significantly reduces the time spent cutting or packing cushioning materials. Simply place the contents between the backing paper and the film and fold the backing paper to securely hold the contents in place. Features: - The material's stretchability allows for accommodating products of varying sizes with a single packaging material. - Eliminating the need to cut or pack cushioning materials leads to a significant reduction in work time and improved work efficiency. - The product remains stationary during transport, so there is no need to fill gaps with cushioning materials.
