Corrugated Board Testing Methods Helps to Determine the Right Packaging 

Start-up businesses need to make an efficient and wise packaging decision. To incur unnecessary packaging cost is not good for your business. You will need to consider the packaging material, design, and labor. Besides, you will need a reliable corrugated box supplier like Belley. It has warehouses in Arizona, Quebec, Vermont, Ontario, Oregon, and British Columbia, which is an advantage to customers for storing their boxes. Overall, a lot of research and proper planning is required to maximize profits and ensure customer satisfaction.

Before your tread in the market looking for corrugated box manufacturing companies get familiar with how to pick the right strength and construction suitable for your needs. The manufacturers use several testing procedures to check packaging quality.

Bursting strength test

It helps to determine the weight a box is capable to carry when subjected to rough handling or pressure. Rubber diaphragm is expanded with the help of hydraulics, which pressurizes the corrugated board walls and it ultimately bursts.

Edge crush test

It helps to check the material quality and its endurance capability while stacking and pallet shipping. Force gets applied on one corner of the box, upright on the ridges until it gets crushed. Results for single or double wall corrugated boxes differ. ECT gives an idea of the maximum load a single carton can carry.

Water resistance of gluing

It helps to determine the impact of moisture and water absorption on the corrugated board’s glue line. The corrugated board gets immersed in water. The glue lines get exposed to water and tested for water absorption and bonding strength.

Cobb sizing tested

It helps to test the porosity of the box when exposed to humidity or moisture. Raw materials used to design corrugated boards are susceptible to absorb and retain water. The board exposed to the water gets squeezed using heavy pressure. The difference in board weight due to retained water is called Cobb value. When the Cobb value is lower the water resistance is better!

Paper density and thickness

For quality determination density and thickness also needs to be determined. Thickness is entirely based on needs. For example, when you need extra padding, the box having large flutes that hold more air is ideal.

Thin boards equipped with dense flutes are needed when packaging needs to be rigid and compact. Flutes are of different types including A, B, C, E, AND F. It determines the strength of the cardboard. C is the most common flute type used.

Other testing methods include puncture resistance, box compression test, scuff resistance method, and chemical analysis. Knowing about the testing procedures will help to decide the correct packaging boxes for your business.
