Plastic woven bags play an important role in modern society, and their printing quality is directly affected by ink.

1. The importance of woven bag ink

Plastic woven bags play an important role in modern society, and their printing quality is directly affected by ink.

This type of ink is different from the ink used in ordinary paper printing, and suitable ink needs to be selected based on the characteristics of plastic woven bags and the usage environment.

The quality of ink directly affects the printing effect and service life of woven bags, so it is very important to understand the small knowledge of woven bag ink.

In actual production, the ink for woven bags often experiences back sticking, which not only affects the printing effect but may also lead to production failures.

Therefore, understanding the causes and solutions of the phenomenon of back sticking is crucial for avoiding unnecessary losses in production.

2. The causes of rebound phenomenon

The appearance of drying after printing is the main manifestation of the phenomenon of back sticking, and the incorrect angle or malfunction of the drying device is one of the reasons for back sticking.

Rapid printing and overly tight rewinding can also lead to back sticking, as well as external environmental factors such as excessive storage pressure.

Excessive ink leakage and back printing are also common reasons for the phenomenon of back sticking.

3. Measures to solve the phenomenon of back sticking

Improving the drying speed of ink is one of the main ways to solve the problem of back sticking.

Check and adjust the angle of the drying device, and arrange the printing speed reasonably to avoid the occurrence of back sticking phenomenon.

When printing, pay attention to avoiding excessive stacking, store the stacking load lightly, and reduce the impact of external environment on the drying of printed materials.

To address the issue of ink back sticking caused by ink leakage and back printing, the ink viscosity can be adjusted or a suitable ink can be replaced.

4. Common knowledge of woven bag ink

The printing of woven bags usually adopts color printing, and due to the different connecting materials in the ink, there may be significant differences in the ink produced by different manufacturers.

The appearance of the ink is a colored oily substance with an acrylic ester odor. The viscosity is 20 ± 5, the fineness is ≤ 10, and the pH value is 8.0-9.0.
