Corrugated paper is a paper material composed of three layers of face paper, corrugated medium paper and bottom paper. It is mainly used to make various types of cartons, cardboard and other packaging materials.
The main properties of corrugated paper include the following aspects:
Strength: Corrugated paper needs to have high strength to ensure that the packaging materials such as cartons and cardboards can withstand the weight of the goods and the shock and vibration during transportation. The detection of strength 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 load-bearing capacity of packaging materials such as cartons and cardboards. The detection of thickness and uniformity can be carried out by measuring the thickness, density and basis weight of corrugated paper.
Shape stability: Corrugated paper needs to have a certain shape stability to ensure that the packaging materials such as cartons and cardboards are not easy to deform or have small deformation. The detection of shape stability can be carried out by measuring the elastic modulus, bending property, rebound rate and other indicators of corrugated paper.
Printability: Corrugated paper needs to have certain printability to ensure the printing quality of the finished cartons, cardboard and other packaging materials. The test of printability can be carried out by measuring the printing applicability, printing quality and printing speed of corrugated paper.
Water resistance: Corrugated paper needs to have a certain degree of water resistance to prevent it from deforming or losing strength in a humid environment. 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, contain no harmful substances, and have 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 . The detection of packaging performance can be carried out by measuring the corrugated height, corrugated shape, cardboard hardness, foldability and other indicators of corrugated paper.
Stretchability: Corrugated paper needs to have a certain degree of stretchability to ensure that it is not easy to tear or break when it is made into cartons, cardboard and other packaging materials. The detection of stretchability can be carried out by measuring the tensile strength, stretch resistance and other indicators of corrugated paper.
Corrugated shape: The corrugated shape of corrugated paper has an important influence on the load-bearing capacity and shape stability of packaging materials such as cartons and cardboard. The detection of corrugated shape can be carried out by measuring the corrugated height, corrugated width, corrugated shape and other indicators of corrugated paper.
Scope of application: corrugated paper is used in a wide range, involving the production of various types of cartons, 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 of corrugated paper, applicable carton type and applicable processing technology and other indicators.
Different types of paper require different detection methods and instruments for detection. The following are some commonly used paper performance testing methods:
Detection of basis weight: Calculate the basis weight per square meter by weighing the weight of paper of a certain size. Use a weighing instrument for measurement.
Detection of thickness and uniformity: measure the thickness of the paper by using a manual or automatic Thickness Gauge, while detecting the uniformity by laser measurement or machine measurement methods.
Strength testing: measure the tensile strength, compressive strength, flexural strength, bursting strength, etc. of paper by using paper strength testing instruments, such as electronic tensile machine, multi-function testing machine, bursting strength Tester, etc.
Surface coating detection: by using surface coating testing instruments, such as scratch Tester, abrasion resistance Tester, adhesion Tester, etc., to measure the uniformity, hardness, wear resistance and adhesion of the surface coating.
Slidability detection: measure the surface smoothness and friction coefficient of the paper by using a sliding test instrument, such as a slip coefficient Tester, a friction coefficient Tester, etc.
Packaging performance testing: use packaging performance testing instruments, such as corrugated compression Testers, corrugated bending Testers, stacking Testers, etc., to measure the compressive strength, bending strength, stacking stability and other properties of packaging materials such as cartons and cardboard.
Printability test: use printing quality testing instruments, such as printing accuracy Tester, printing speed Tester, ink adhesion Tester, etc., to measure the printing quality, printing speed and ink adhesion of paper.
Environmental testing: measure the content of harmful substances such as volatile organic compounds, heavy metals, and chloride ions in paper by using environmental testing instruments, such as volatile organic compound Testers, heavy metal Testers, and chloride ion Testers.
The above methods are only a part of paper performance testing, and the specific testing methods and instruments need to be selected according to different paper types and performance indicators.
