Main reasons for poor printing fastness of ordinary woven bags

Poor printing fastness of ordinary woven bags refers to the fading of ink layer after printing. It may be that the corona treatment on the product surface is improper, or the temperature and relative humidity in the printing workshop are too high; The dissolved hydrogen bonding force of ink system may also be too different from that of ordinary woven bag substrate. Mechanical transmission is unstable. Due to the fluctuation of mechanical transmission, the width of wire rod also fluctuates. Ordinary woven bag manufacturers have not effectively controlled this problem, but we believe that this technical problem will be solved in the near future, so that consumers can use ordinary woven bags with better quality.

If the accessories are of good quality, it can be seen that the appearance of ordinary woven bags is also more exquisite. Of course, in the production of ordinary woven bags, in addition to auxiliary materials, many additives should be added in the production and processing process. Although the quantity is small, it also plays a certain role in the quality of products and improves our convenience.

Due to the uncertainty of various parameters of the wholesale price of ordinary woven bags and the uncertainty of production process, there will be uncertainty in the color, weight and density of each ordinary woven bag. In order to avoid unnecessary trouble, it is usually recommended to send some samples to customers first and distribute them when they can be used. This is an example principle.

Usually, we will randomly select two bundles, and then randomly select about 10 ordinary woven bags from one bundle for comparison. For high-quality products, the printed content is clear, the information is expressed accurately, will not fade, and there will be no shadow and ink during use.

Ordinary woven bags are widely used in all walks of life. Ordinary woven bags are affected by many factors in the production process. Decomposition during processing not only has a direct negative impact on the physical properties, mechanical properties and appearance of plastic bags, but also has a negative impact on the stability of plastic bags in use.
