The reason why the color strength of the woven bag is not strong

Insufficient color strength of woven bags is mainly manifested in the fact that after the printing of the woven bags, the ink layer is easy to fade. The main reasons are as follows:

1. Substrate: The corona on the surface of the PP or PE is not treated properly during production.

2. Environment: Printing shop temperature and relative humidity are large.

3. Raw materials: The dissolved hydrogen bond strength of the ink and solvent system is too different from the hydrogen bond strength of the woven bag substrate.
