Corrugated paper is a paper material composed of three layers of face paper, corrugated core paper and bottom paper, which is mainly used to make various types of carton, cardboard and other packaging materials.

The main performance of corrugated paper includes the following aspects:

Strength: Corrugated paper needs to have high strength to ensure that the carton, cardboard and other packaging materials made can withstand the weight of goods and vibration and vibration during transportation. Strength detection can be carried out by measuring the tensile strength, compressive strength and other indicators of corrugated paper.

Thickness and uniformity: The thickness and uniformity of corrugated paper have an important impact on the dimensional stability and bearing capacity of carton, cardboard and other packaging materials made. The detection of thickness and uniformity can be carried out by measuring the thickness, density and basic weight of corrugated paper.

Shape stability: Corrugated paper needs to have a certain shape stability, in order to ensure that the carton, cardboard and other packaging materials are not easy to deformation or deformation is small. The shape stability can be detected by measuring the elastic modulus, bending, rebound rate and other indicators of corrugated paper.

Printable: Corrugated paper needs to have a certain printable ability to ensure the printing quality of carton, cardboard and other packaging materials. The printability can be tested by measuring the printing suitability, printing quality and printing speed of corrugated paper.

Water resistance: Corrugated paper needs to have a certain water resistance to prevent it from deforming or losing strength in humid environments. The detection of water resistance can be carried out by measuring the water absorption, toughness and other indicators of corrugated paper.

Environmental protection: corrugated paper needs to meet environmental protection standards, do not contain harmful substances, no pollution to the environment. The detection of environmental protection can be carried out by measuring the volatile organic compounds, heavy metals, chloride ions and other indicators of corrugated paper.

Packaging performance: The packaging performance of corrugated paper is one of its important performance indicators, including packaging tightness, dimensional stability and stacking stability. The detection of packaging performance can be carried out by measuring the corrugated height, corrugated shape, cardboard hardness, foldability and other indicators.

Stretchability: Corrugated paper needs to have a certain stretchability to ensure that it is not easy to tear or rupture when it is made into carton, cardboard and other packaging materials. Tensile testing can be carried out by measuring the tensile strength, tensile resistance and other indicators of corrugated paper.

Corrugated shape: The corrugated shape of corrugated paper has an important impact on the carrying capacity and shape stability of carton, cardboard and other packaging materials. The detection of corrugated shape can be carried out by measuring the corrugated height, corrugated width, corrugated shape and other indicators.

Scope of application: Corrugated has a wide range of uses, involving the production of various types of carton, cardboard and other packaging materials, which need to be tested and evaluated according to specific application requirements. The detection of the scope of application can be carried out by measuring the applicable environment, applicable carton type and applicable processing technology of corrugated paper.

Performance of detection
Different kinds of paper need to use different detection methods and instruments in the detection. The following are some commonly used paper performance testing methods:

Detection of base weight: calculate the base weight per square meter by weighing the weight of a certain size of paper. Measurements were made using a weighing instrument.

Detection of thickness and uniformity: The thickness of the paper is measured by using a manual or automatic thickness gauge, while the uniformity is detected by laser or machine measurement methods.

Strength testing: through the use of paper strength testing equipment, such as electronic tensile machine, multi-function testing machine, rupture strength tester, etc., to measure the tensile strength of paper, compressive strength, flexural strength, rupture strength, etc.

Surface coating testing: through the use of surface coating testing instruments, such as scratch tester, wear resistance tester, adhesion tester, etc., to measure the surface coating uniformity, hardness, wear resistance and adhesion properties.

Sliding detection: through the use of sliding testing instruments, such as sliding coefficient tester, friction coefficient tester, etc., to measure the surface smoothness of paper and friction coefficient and other properties.

Packaging performance testing: through the use of packaging performance testing instruments, such as corrugated compression tester, corrugated bending tester, stacking tester, etc., to measure the carton, cardboard and other packaging materials compression strength, bending strength, stacking stability and other properties.

Printability testing: through the use of printing quality testing instruments, such as printing accuracy tester, printing speed tester, ink adhesion tester, etc., to measure the performance of paper printing quality, printing speed and ink adhesion.

Corrugated paper performance test subjects and equipmentthrough the use of environmental testing instruments, such as volatile organic compounds tester, heavy metal tester, chloride ion tester, etc., to measure the content of volatile organic compounds, heavy metals, chloride ions and other harmful substances in paper.

The above methods are only a part of the paper performance detection, the specific detection methods and instruments need to be selected according to different paper types and performance indicators.
