After World War II, honeycomb cardboard packaging began to be used in European and American countries. Currently, 80-90% of the doors used in Western countries use honeycomb card as a filling material to reduce the usage of wood and steel and to maximize material utilization. In the past, honeycomb structure technology was a dual-use technology restricted by the West from being exported to China. However, starting from the early 1990s, China began to research and promote card honeycomb material products, which have seen significant progress and development over the past decade. Below, we will discuss the advantages and applications of honeycomb cardboard packaging.
Compared to other types of board structures, honeycomb cardboard packaging is lightweight, uses less material, and is cost-effective. It has the highest strength-to-weight ratio, making the performance-to-price ratio of its products excellent. This is the key to the success of honeycomb card.
Honeycomb packaging machine for cardboard has high strength, a smooth surface, nearly isotropic qualities, and good structural stability, making it less prone to deformation. Its outstanding compressive and bending resistance are the most important characteristics required for box packaging materials.
It has good impact resistance and cushioning properties. Made of flexible paper cores and facing papers, honeycomb card exhibits good toughness and resilience. The unique honeycomb structure provides excellent cushioning performance, with a higher energy absorption per unit volume than all other cushioning materials. High-thickness honeycomb card can replace the widely used EPS plastic foam cushions.
After being stretched by a paper stretcher, the corrugated kraft paper forms an angular honeycomb unit with a liner of soft white paper, creating a three-dimensional honeycomb cushion. This prevents the wrapped product from shaking and scraping, providing excellent cushioning, shock resistance, and scratch prevention.
Made by paper honeycomb manufacturers, honeycomb cardboard packaging is easier to process after recycling. The recycling and processing procedures are simple, saving a lot of costs and improving utilization efficiency.
The excellent performance of honeycomb composite materials in honeycomb cardboard packaging has significantly reduced product costs, leading to its widespread application in construction, aviation, transportation, and packaging industries. As a result, honeycomb card and other honeycomb material products have become an important new type of material. The excellent mechanical properties and energy absorption capabilities, good formability, and low cost of honeycomb cardboard packaging make it prominent in the industrial packaging field. It can be widely used for precision machinery, machine equipment, electronic and computer products, automotive parts, new energy packaging, and logistics storage. It can also be used for food packaging and void filling during packaging. In the United States, up to 50,000 tons of paper honeycomb are used for packaging every year (equivalent to 40-60 million square meters of 20-30mm thick stretched core material), known as green packaging boxes. However, in China, the use of card honeycomb for packaging is a potential market that urgently needs to be developed for the benefit of the country and its people.
