Like many other products and materials, corrugated board comes in different qualities. The higher the quality, the more advantages it has for companies and consumers. We have compiled a list of factors that influence the quality of corrugated board and how you can recognize high quality. 

Companies and consumers benefit from corrugated board with high quality

Corrugated board is a versatile and economical material that can be used in many ways. For example, it can be used for challenging tasks such as shipping heavy spare parts.

The quality of corrugated board is of great importance for companies and users, as it has a direct influence on functionality and durability.

For suppliers of corrugated board, it is important that the quality of the corrugated board produced is high to ensure customer satisfaction and to stand out from the competition.

High quality corrugated board also helps reduce recall or warranty costs.

Corrugated board boxes are used for transport a variety of products because they are sturdy and durable. From small items and textiles to heavy or bulky items, it's hard to imagine business without these cartons. For industries of all kinds, corrugated cardboard boxes are an elementary basis in the growing shipping business.

But also the stationary retail trade and wholesale trade depend on high quality of corrugated cardboard boxes and weather-resistant transport of goods.

For corrugated cardboard boxes to do their job safely and be versatile, they must be robust enough to withstand transport conditions. It is therefore essential that they meet the requirements of the product being packaged and are sufficiently protected to prevent damage during transport.

High-quality corrugated board is hard-wearing and durable, which means it can be used for longer and the cost of using corrugated board is reduced. However, not only companies and suppliers, but also consumers and users expect good quality from boxes made of this material. Good quality corrugated board helps to ensure that the product to be packaged is transported safely and reaches the recipient intact.

Several factors are responsible for the stability and integrity during transportation with a box made of corrugated board:

• Design of the flap closure
• Adhesive strength and durability of adhesive tapes used
• Padding of the transported goods
• Storage and storage time during transport

The structural basis is provided by the corrugated board itself, which must be matched to the intended use and the means of transport. Only with cartons in corrugated board of sufficient quality will all items arrive safely during shipping and transport. 

These criteria characterize good corrugated board

With high quality corrugated board, products of all kinds can be safely packaged and transported without damage. For this purpose, corrugated board consists of several layers of paper that are glued together to achieve high stability and durability. This is the only way to ensure that the corrugated board protects the product to be packed from impacts, dirt and moisture.

The load capacity of corrugated cardboard boxes depends on various factors, such as the thickness and quality of the corrugated cardboard, the size and shape of the box, and the type of product being packaged. As a rule, corrugated cardboard boxes can easily carry weights of up to 25 kg.

However, there are also special boxes made of corrugated board, which are designed for the transport of heavier goods and can carry up to 50 kg or more. The choice of corrugated cardboard carton must be adapted to the weight of the product to be packed to provide safe transportation.

It should be remembered that the load capacity of corrugated cardboard boxes also depends on the type of transport and handling. For example, cartons that are stacked during transport might require a higher load capacity than if they are transported individually. Cartons and corrugated board material should be matched to the transport requirements.

Put to the test: high-quality corrugated board has to prove itself

The quality of corrugated board is checked using various tests. This ensures that it meets the desired requirements and is suitable for the intended use.

These are the most important quality tests for corrugated board:

1. burst strength
The burst strength of corrugated board is measured by testing the strength of the corrugated board at its weak point, the fold. A high burst strength means that the corrugated board is less likely to crack or break when loaded.

2. puncture resistance
The puncture resistance of corrugated board is tested by pressing the corrugated board onto a solid surface until it is punctured. A high puncture resistance makes it less likely that the corrugated board will break while subjected to a load.

3. edge crush resistance
The edge crush resistance of corrugated board is measured by loading the corrugated board on an edge until it buckles or breaks. The higher the edge crush resistance, the less likely the corrugated board is to buckle or break under load.

4. flat crush resistance
The flat crush resistance of corrugated board is measured by pressing the corrugated board onto a flat surface until it buckles or breaks. Again, a high flat crush resistance means that the corrugated board is less likely to buckle or break when loaded.

5. Cobb value
The Cobb value of corrugated board is measured by pressing the corrugated board onto a solid surface until it absorbs a certain amount of liquid.

The Cobb value indicates how much liquid the corrugated board absorbs and is given in grams per square meter. A low Cobb value means that the corrugated board absorbs less liquid and is therefore less likely to be soaked.

The results of these tests determine the corrugated board grade. The grade designation consists of one digit before and two digits after a dot. The digit before the dot indicates how many flutes the corrugated board has. The digits after the dot come from the tests listed that measure the strength and rigidity of the corrugated board.

Here are some typical grade values for single flute, double flute and triple flute corrugated board:

• Single shaft: 1.30
• Double shaft: 2.40
• Triple wave: 3.00

The quality tests ensure that corrugated board meets the requirements and is suitable for the designated use.

Liner paper and fluting paper - the basic material for high quality corrugated board.

To assess the quality of corrugated board , it is important to know the difference between liner paper and fluting paper. Both types of paper are used in the packaging industry, but they differ in their production and properties.

Blanket paper consists of a single layer and is mainly used for packaging light products. It is light and soft and is usually used to cushion products to prevent damage during transportation.

Corrugated paper, also known as corrugated board, consists of several layers of paper glued together to achieve high stability and durability. It is mainly used for packaging heavy or bulky products as it has a high load bearing capacity. Corrugated paper is also more weather resistant than blanket paper, making it more suitable for transporting products over longer distances.

Blanket paper can still be distinguished into different sub-varieties, depending on the property and application. These are the main types of blanket paper:

Kraftliner
Kraftliner is a type of blanket paper made from recycled paper and has high tear strength. It is mainly used for packaging heavy or bulky products and is also weather resistant.

Testliner
Testliner is made from virgin fiber paper and has medium tear strength. It is mainly used for packaging medium-heavy products and is less weather resistant than kraftliner.

Schrenzpapier
Schrenzpapier is made of virgin fiber paper and has low tear strength. It is mainly used for packaging light products and is less weather resistant than kraftliner or testliner.

In summary, liner paper is mainly used for packaging light products, while corrugated paper is mainly used for packaging heavy or bulky products. Both types of paper have different properties and applications and are used in the packaging industry.

Prepare corrugated cardboard boxes for transport

In order to prepare corrugated cardboard and corrugated cardboard boxes for transport, there are a few points to consider:

1. Choose the right box: Use a box that corresponds to the weight and size of the product to be packed. This will ensure that the product will not be damaged in transit. 2.

Pack the product carefully and use filling material such as packing paper, foam or bubble wrap. The product to be transported should be enclosed as tightly as possible by the cardboard walls or the filling material - this applies especially to heavy, small products. So make sure that the product cannot slide around in the carton during transport.

3. close the carton securely using tape or other packing materials that ensure secure closure of the corrugated carton. No one wants the carton to open during shipping and compromise the integrity of the shipment.

Mark and label the box clearly with all the information required for shipping and transport. This ensures that the carton arrives at the correct address.

5. storage: To store corrugated boxes, it is best to use a dry place with moderate room temperature. Place the corrugated cardboard vertically for storage - stacking can damage the corrugated structure of the corrugated cardboard at the bottom: Because cardboard also has weight.

By paying attention to these points, you ensure that corrugated board and corrugated cardboard are well prepared for transport and that the transport takes place without damage.
