Color boxes lapping adhesives play an important role in improving the smoothness of printed packaging surfaces.
Mechanism of action of color boxes lapping adhesives
Physical grinding: color boxes lapping adhesives physically grind the surface of printed packaging through the tiny abrasive particles they contain. These abrasive particles can remove tiny bumps, scratches or uneven parts of the surface, making the surface smoother.
Filling and leveling: Certain components in the abrasive adhesive can penetrate into the tiny pores on the surface of the printed packaging and play a filling role. By filling, the roughness of the surface can be further reduced and the smoothness can be improved.
Chemical action: Some abrasive adhesives may contain components that can react chemically with the surface materials of the printed packaging. These chemical reactions help to change the microstructure of the surface, thereby achieving the effect of improving smoothness.
Application notes
Choose the right abrasive adhesive: Choose the right abrasive adhesive based on the type, hardness, thickness and other factors of the printed packaging material. Different types of abrasive adhesives are suitable for different materials, and improper selection may result in poor results or damage to the material.
Control grinding time and strength: Too long grinding time or too much strength may cause excessive wear on the surface of the printed packaging, or even damage its structure. Therefore, the time and strength need to be strictly controlled during the grinding process to ensure that the ideal smoothness is achieved without damaging the material.
Pay attention to cleaning and maintenance after grinding: After grinding, the grinding residue on the surface should be removed in time to avoid interference with the subsequent printing or packaging process. At the same time, clean and maintain the grinding equipment and tools to extend their service life and maintain the grinding effect.
Actual application effect
The smoothness of the printed packaging surface treated with color boxes lapping adhesives is significantly improved, making the printed pattern clearer and fuller.
The smooth surface also helps to improve the adhesion and uniformity of the printing ink, thereby improving the quality of the printed product.
In addition, the smooth surface can also reduce scratches and damage caused by friction during the packaging process, and improve the overall aesthetics and durability of the product.
In summary, color boxes lapping adhesives effectively improve the smoothness of the printed packaging surface through multiple mechanisms such as physical grinding, filling leveling and chemical action. In actual application, it is necessary to pay attention to selecting the appropriate grinding glue, controlling the grinding time and strength, and paying attention to cleaning and maintenance after grinding.
