In the modern packaging industry, corrugated cardboard is widely used in the packaging of various items due to its light weight, easy processing, high strength and environmental protection. Among them, corrugated 3-layer single-hole paper knife card is a special packaging material. With its unique single-hole structure and foldability, it has shown remarkable performance in optimizing space utilization and adapting to the packaging of items of different shapes and sizes. Advantages.The corrugated 3-layer single-hole paper knife card is composed of three layers of corrugated cardboard. The middle layer is a corrugated corrugated core paper, and the upper and lower layers are flat cardboard, which are bonded by adhesives. This structure gives corrugated cardboard good compressive strength and cushioning properties. The single-hole design refers to a single opening reserved on the knife card, which is convenient for inserting, fixing and separating items, effectively avoiding collision and damage of items during transportation.In terms of optimizing space utilization, the corrugated 3-layer single-hole paper knife card achieves precise control of packaging space through flexible folding and combination methods. First, the knife card can be customized according to the shape and size of the item, ensuring that every space is fully utilized and reducing unnecessary gaps. Secondly, by folding different parts of the knife card, the volume of the lining package can be adjusted to accommodate items of different sizes. For example, for cylindrical items, the blade can be folded to form a ring structure to tightly wrap the item; for flat items, the blade can be unfolded into a flat surface to provide stable support.In terms of adapting to the packaging of diverse items, the design of the corrugated 3-layer single-hole paper knife card is also highly flexible and customizable. The single-hole structure not only facilitates the insertion and fixation of items, but can also be adapted to items of different shapes and sizes by adjusting the position and size of the holes. For example, for fragile items, additional cushioning material can be added around the holes to enhance the protective effect; for heavy items, the load-bearing capacity of the packaging can be improved by increasing the number of layers of knife cards or changing the thickness of the corrugated core paper.In addition, corrugated 3-layer single-hole paper knife card also has good recyclability and environmental protection. As the global awareness of environmental protection increases, more and more companies are paying attention to the sustainability of packaging. As a recyclable material, corrugated cardboard not only reduces the environmental pollution caused by packaging waste, but also promotes the recycling of resources.In practical applications, corrugated 3-layer single-hole paper knife card has been widely used in packaging of electronic products, food, daily necessities and other fields. Through precise design and customization, these knife cards not only effectively protect the safety of items during transportation, but also improve the efficiency and aesthetics of packaging.In summary, the corrugated 3-layer single-hole paper knife card shows significant advantages in optimizing space utilization and adapting to the packaging of diverse items through its unique single-hole structure and foldability. With the continuous advancement of packaging technology and the increasingly diversified consumer demands, the application prospects of corrugated 3-layer single-hole paper knife card will be broader.
