Inner trays are made from a variety of materials, commonly including foam, paper, and plastic. Among them, foam inner trays are widely popular due to their excellent cushioning and shock absorption. Through a one-piece molding process, foam inner trays can tightly conform to the shape of the product, providing customized protection solutions. Their density, color, and cushioning performance can all be adjusted according to specific needs to meet the packaging requirements of different products. High-density foam inner trays have stronger compression resistance and better cushioning effects, suitable for packaging precision instruments and fragile items; while low-density foam inner trays are lighter and suitable for transportation scenarios with strict weight requirements.
Besides foam inner trays, paper inner trays are also gradually gaining market favor due to their environmentally friendly and recyclable characteristics. Paper inner trays are typically made from materials such as corrugated cardboard or honeycomb cardboard, and are formed into various shapes through folding and gluing processes. They not only have good cushioning performance but also reduce packaging weight to a certain extent, lowering transportation costs. At the same time, the environmental friendliness of paper inner trays aligns with the development trend of modern green packaging, helping to enhance corporate image and market competitiveness.
