Containerboard performance testing and testing equipment

Containerboard is a paper material specially used to make cartons, usually consisting of two layers of core paper and face paper.

The main performance indicators of containerboard include the following aspects:

1. Strength: Containerboard needs to have high strength to ensure that the cartons made 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 the cardboard paper.

2. Thickness and uniformity: The thickness and uniformity of the containerboard has a significant impact on the dimensional stability and load-bearing capacity of the resulting carton. The detection of thickness and uniformity can be carried out by measuring the thickness, density and basis weight of the container board.

3. Elasticity and hardness: The containerboard paper needs to have a certain degree of elasticity and hardness to ensure that the cartons made are not easily deformed or deformed less. The detection of elasticity and hardness can be carried out by measuring the elastic modulus, bendability, rebound rate, hardness and other indicators of the containerboard paper.

4. Printability: Container board needs to have certain printability to ensure the printing quality of the finished carton. The test of printability can be carried out by measuring the printing applicability, printing quality and printing speed of the cardboard.

5. Water resistance: Containerboard 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 the cardboard paper.

6. Environmental protection: containerboard 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 in the container board.

7. Packaging performance: The packaging performance of containerboard 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 of the cardboard.

8. Scope of application: Containerboard is used in a wide range, involving the production of various types of cartons, and needs 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 the container board, the applicable carton type and the applicable processing technology and other indicators.

Detection performance

The performance testing of container board usually includes the following aspects:

1. Detection of basis weight: Calculate the basis weight per square meter by weighing the weight of a certain size of cardboard. Use a weighing instrument for measurement.

2. Inspection of thickness and uniformity: measure the thickness of the containerboard by using a manual or automatic Thickness Gauge, and at the same time inspect the uniformity by laser measurement or machine measurement.

3. Strength testing: measure the tensile strength, compressive strength and other indicators of the cardboard paper by using the cardboard paper strength testing equipment, such as electronic tensile machine, multi-function testing machine, burst strength Tester, etc.

4. 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 cartons made of cardboard paper.

5. 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 cardboard paper.

6. Environmental testing: use environmental testing instruments, such as volatile organic compound Testers, heavy metal Testers, chloride ion Testers, etc., to measure the content of volatile organic compounds, heavy metals, chloride ions and other harmful substances in the container board.

The specific detection methods and instruments of containerboard paper are as follows:

1. Detection of basis weight: Take a sample of a certain size, weigh it, and calculate the basis weight per square meter. Weighing is usually performed using precision electronic scales or balances.

2. Inspection of thickness and uniformity: Use manual or automatic Thickness Gauges to measure the thickness of the containerboard, and use laser measurement or machine measurement methods to detect uniformity. Manual Thickness Gauges usually use hand-held thickness measuring instruments, automatic Thickness Gauges usually use laser triangulation to measure thickness, and the method of detecting uniformity can be carried out using machine vision systems.

3. Strength testing: use the cardboard paper strength testing instrument to measure the tensile strength, compressive strength and other indicators of the cardboard paper. Usually use electronic tensile machine, multi-function testing machine, burst strength Tester and other equipment for testing.

4. Packaging performance testing: Use packaging performance testing instruments to measure the compressive strength, bending strength, stacking stability and other properties of cartons made of cardboard paper. The corrugated compression Tester can measure the compression performance of corrugated cardboard, the corrugated bending Tester can measure the bending performance of corrugated cardboard, and the stacking Tester can measure the stacking stability of corrugated boxes.

5. Printability testing: Use printing quality testing equipment to measure the printing quality, printing speed and ink adhesion of cardboard paper. The printing accuracy Tester can measure the printing quality, the printing speed Tester can measure the printing speed, and the ink adhesion Tester can measure the adhesion performance of ink and paper.

6. Environmental testing: Use environmental testing instruments to measure the content of volatile organic compounds, heavy metals, chloride ions and other harmful substances in the container board. The volatile organic compound Tester can measure the content of volatile organic compounds in the cardboard, the heavy metal Tester can measure the content of heavy metals in the cardboard, and the chloride ion Tester can measure the content of chloride ions in the cardboard.

The above methods are only part of the performance testing of container board, and the specific testing methods and instruments need to be tested according to different properties.
