Comparison of Cushioning Performance between Honeycomb Paper and Corrugated Paper

For fragile products, such as glass products, ceramic products, handicrafts, bottled food and beverage, as well as sophisticated electronic, electrical and communication products, it is necessary to minimize the damage to products caused by the transportation and circulation process. The transportation package or buffer package plays a key role here. The main forms of existing transport packaging are:

Outer packaging

Outer packaging is an effective way to protect fragile products from damage. It is generally required that the outer packaging of fragile products should have a certain compressive strength and puncture resistance strength, which can protect the fragile products from damage under normal transportation, storage and stacking conditions.The most typical and commonly used outer packaging of fragile products is corrugated boxes. Some large and heavy fragile products are packed in honeycomb cardboard boxes. Some lighter or higher compressive strength products, such as glass cans, are transported on pallets with wound film packaging instead of corrugated boxes.

No matter what kind of fragile outer package, the words "fragile" and corresponding patterns shall be marked on the upper left corner of the four sides.

Corrugated box

Corrugated carton is the largest transport packaging container currently used. The commonly used corrugated box for fragile products is made of three or five layers of corrugated cardboard.

Corrugated cardboard generally has four types: A, B, C and E. A, B and C corrugated cardboard can be used to make cartons for fragile products. The difference lies in the higher and thinner A-shaped edges, the lower compressive strength, the lower and denser B-shaped edges, the higher compressive strength, and the intermediate C-shaped edges. The selection of cardboard boxes with different shapes or layers is mainly based on the importance of the contents and the requirements for compressive strength.

In the past, due to the backward transportation conditions in China, the phenomenon of rough loading and unloading often occurred. The domestic demand for 5-layer corrugated boxes was large, accounting for about 70%. However, with the improvement of transportation conditions in China in recent years, the application proportion of 3-layer corrugated boxes has increased year by year. And with the change of sales methods, the transport packaging of many fragile products is closer to the sales packaging. The design of corrugated boxes is becoming more and more complex, and the quality of printing and decoration is also getting higher and higher. Many of them have been grandly mounted on the shelves of supermarkets.

Honeycomb cardboard box

Honeycomb cardboard box is a box container made of honeycomb cardboard. Honeycomb paperboard is light in weight, high in compression resistance, bending resistance and shear strength, and has good cushioning and vibration isolation performance. There are three kinds of packaging boxes with honeycomb paperboard as the main material. One is the composite packing box. The outer layer of the box is made of fiberboard or plywood with strong puncture ability, the middle layer is honeycomb paper core, and the inner wall is bonded with straw paperboard; The other is full honeycomb cardboard packing box. That is, honeycomb paper is used as the sandwich, and the inside and outside are bonded with cardboard; The third is the lined packaging box. The corrugated box is used as the box, and the upper and lower walls of the box are lined with honeycomb cardboard, which has strong shock resistance, compression resistance, thermal insulation and puncture resistance.

Compared with traditional corrugated boxes, honeycomb cardboard boxes have better mechanical properties. For example, experiments such as destructive drop, heavy object stacking, and rolling of actual packaging show that the damage rate of fragile items in honeycomb cardboard boxes is 50%~97% lower than that in corrugated boxes; 600 kg weight placed on the empty box will not deform after pressure test for three months, and polystyrene liner is not required; The weight ratio with corrugated boxes of the same specification is 2:5, which can save 60% of cardboard. The popularization and application of this kind of carton will play a positive role in reducing the breakage rate of goods in the circulation process and improving the quality of packaging products. In particular, honeycomb cartons are the best choice for jade carvings and handicrafts with high value.
