Introduction
Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly known as “corrugated sheet”, “corrugated paper”, “corrugated core paper”, “corrugated paper core”, “corrugated base paper”) and one layer of cardboard (also known as “boxboard”, “boxboard”).
Honeycomb paperboard is made according to the principle of natural honeycomb structure. It is a new type of environmentally friendly and energy-saving material with a sandwich structure, which is made by connecting corrugated paper into countless hollow three-dimensional regular hexagons by gluing to form an integral load-bearing member – the paper core, and gluing surface paper on both sides.
The main differences between honeycomb cardboard and corrugated cardboard are as follows:
Structure and composition:
Honeycomb cardboard is a material composed of a honeycomb paper core between two layers of paper. This structure makes honeycomb cardboard have high compressive strength and impact resistance. Corrugated cardboard is made of a layer of flat cardboard and a layer of corrugated cardboard alternately bonded together. This structure makes corrugated cardboard have good compressive resistance and cushioning performance.
Performance difference:
Flat compression strength: The flat compression strength of honeycomb cardboard is much higher than that of corrugated cardboard. Under the condition of a certain amount of consumables, the flat compression strength of honeycomb cardboard decreases with the increase of pore size
Lateral compression strength: The lateral compression strength of corrugated cardboard is much higher than that of honeycomb cardboard, while the lateral compression strength in the transverse direction is lower than that of honeycomb cardboard.
Bending strength: The bending strength of honeycomb cardboard is higher than that of corrugated cardboard, and its bending strength increases with the increase of pore size.
Peeling strength: The peeling strength of corrugated cardboard is higher than that of honeycomb cardboard; the peeling strength of honeycomb cardboard increases with the decrease of pore size.
Application and advantages:
Advantages of honeycomb cardboard: light weight, less material, and low cost. Compared with other types of sheet materials, honeycomb sandwich structure has the largest strength/mass ratio, so its finished product has a good performance/price ratio, which is the key to the success of honeycomb paperboard. High strength, smooth surface, not easy to deform. Honeycomb sandwich structure is approximately isotropic, with good structural stability and not easy to deform. Its outstanding compressive and bending resistance are the most important characteristics required for box packaging materials. Sound absorption and heat insulation. The interior of the honeycomb sandwich structure is a closed small chamber filled with air, so it has good sound insulation and heat preservation performance. No pollution, in line with the modern environmental protection trend. Honeycomb paperboard is made entirely of recyclable paper materials and can be 100% recycled and reused after use.
Advantages of corrugated paperboard: The advantages of corrugated paperboard are: strong strength, mature products, and strong talents, but enterprises have overproduction and urgently need to develop new markets.
Which One Should You Choose?
Advantages of corrugated paper:
Good cushioning performance: Corrugated paperboard has a special structure, and 60-70% of the volume of the paperboard structure is empty, so it has good shock absorption performance and can prevent the packaged items from collision and impact.
Light and strong: Corrugated paperboard is a hollow structure, and less material is used to form a rigid box, so it is light and strong. Compared with wooden boxes of the same volume, it is only about half the weight of wooden boxes.
Small size: Corrugated boxes can be folded into a flat plate during storage and transportation, which is convenient for storage and transportation; when used, they can be opened to form a box, and the volume is much smaller than wooden boxes and plywood boxes of the same volume.
Good plasticity: It can be customized according to the shape of the packaged items.
Advantages of honeycomb paperboard:
Higher compressive strength and impact resistance: It can effectively protect the packaged items.
Good moisture-proof performance: Suitable for long-distance transportation and storage.
Light weight, high strength, high rigidity: Due to the structure of honeycomb paperboard, it has strong compressive and flexural bearing capacity.
Good cushioning performance: Honeycomb carton panels have good toughness and resilience.
Heavy load-bearing capacity: The load-bearing capacity of honeycomb carton is 2-10 times that of five-layer corrugated carton, and can replace solid wood board.
Summary
Although honeycomb paperboard and corrugated paperboard compete with each other in some aspects, they each have their own unique advantages and applicable scenarios. In practical applications, the appropriate material can be selected according to specific needs.
