Custom Inkjet PP Paper: In-depth analysis of physical performance testing and quality inspection

1. Physical performance testing: a hard indicator for measuring quality
Physical performance testing is an important means to measure the quality of Custom Inkjet PP Paper. It tests various physical indicators of paper to evaluate its performance in actual applications. The following are some key physical performance test items:

1. Thickness test
Thickness is a basic physical property of paper, which directly affects the printing effect and the durability of paper. Using professional thickness measuring instruments to measure different parts of the paper can ensure the thickness consistency of the paper. Paper with uniform thickness is not prone to curling, wrinkling and other problems during printing, thereby ensuring the flatness of the printing effect.

2. Tensile strength test
Tensile strength refers to the maximum tensile force that paper can withstand before breaking, which reflects the tensile properties and strength of paper. By testing the tensile strength of paper with a tensile tester, the tear resistance of paper during printing, transportation and use can be evaluated. Higher tensile strength means that the paper is less likely to break and can better protect the printed content.

3. Bursting strength test
Bursing strength refers to the pressure required for paper to break under specified conditions, which reflects the ability of paper to resist external force penetration. Using a bursting strength tester to test paper can evaluate the compression resistance and puncture resistance of paper. For packaging or display materials that need to withstand a certain amount of pressure, bursting strength is an important quality indicator.

4. Abrasion resistance test
Abrasion resistance refers to the ability of paper to resist wear, which determines the durability and service life of paper. By simulating the friction and wear under actual use conditions, the abrasion resistance test of paper can evaluate the surface condition of paper after multiple frictions. Paper with good wear resistance can maintain the printing effect for a long time and reduce the blurred image or unclear text caused by wear.

2. Quality inspection: comprehensive considerations to ensure quality
On the basis of physical performance testing, combined with multiple aspects of quality inspection, the quality of Custom Inkjet PP Paper can be more comprehensively evaluated. The following are some key steps of quality inspection:

1. Appearance inspection
Appearance inspection is the first step of quality inspection. It preliminarily judges the quality of paper by observing the color, flatness, smoothness, dust and spots of paper. Paper with uniform color, smooth surface and no dust spots usually means that its production process is more mature and its quality is more reliable.

2. Printing effect test
Printing effect test is a key link in testing paper quality. Use a standard inkjet printer and ink to print the paper and observe indicators such as color reproduction, drying speed, and image clarity. Paper with high color reproduction can present a more realistic printing effect; paper with fast drying speed can reduce the risk of ink smudge; paper with high image clarity can ensure the readability of printed content.

3. Special performance test (if necessary)
For certain specific application scenarios, such as outdoor advertising, waterproof labels, etc., special performance tests are required for paper. Waterproof test can evaluate the performance of paper in humid environment; scratch resistance test can evaluate the durability of paper when rubbed. These special performance tests help ensure that the paper can meet the needs of specific application scenarios.

4. Quality control and continuous improvement
During the quality inspection process, strict quality control of the paper production process is also required to ensure the quality stability of each batch of paper. According to the results of quality inspection, the production process and formula are adjusted in time to continuously improve the quality performance of paper. Through continuous quality control and improvement, the market competitiveness of Custom Inkjet PP Paper can be continuously improved.
