Selection of printing ink for reusable shopping bags
The printing process of reusable shopping bags generally adopts screen printing, which is often called 'silk screen printing '.
However, in the actual production process, customers often say: why do some bags have good printing effect and some have poor printing effect?
Of course, this has a great relationship with the proficiency of printing workers and printing technology. At the same time, on the other hand, it also has a great relationship with the choice of printing ink.
Usually, there are two kinds of printing inks for us to choose from, one is water-based elastic mucilage and the other is ink.
For example, the printing on the general non-woven bag is a water-based elastic mucilage. The biggest characteristic of this water-based elastic mucilage is that the printing effect has obvious concave and convex feeling and the coverage rate is good, it is washable and basically has no peculiar smell, while ink is generally used in screen printing of ordinary objects, such as the surface of metal boxes, etc. The biggest characteristic of this printing process is high printing precision.
Why is the printing on our environmental protection bags basically using water-based Elastic Glue? There are several main reasons for this: 1.
Water-based Elastic Glue is a relatively environmentally friendly ink, and there is basically no odor, so since we are making environmentally friendly bags, of course, we must choose environmentally friendly ink. 2.
Different from the surface of ordinary objects, the mesh on the surface of the fabric is relatively large, and the general ink printing is selected. If the coverage rate is not good, that is to say, after the printing is finished, the background color of the fabric itself is exposed, this kind of printing effect will be very ugly, so because the surface properties of the fabric itself determine that we use water-based Elastic Glue.
There is also a situation where some customers' orders need to be exported to some European and American countries, so there are relatively higher requirements for the environmental protection performance of the ink, then this time, we need to be more cautious, so as not to pass the environmental protection test when importing from other countries.
In this case, we generally recommend that customers choose water-based elastic mucilage with high environmental performance. This water-based elastic mucilage with high environmental performance not only has low heavy metal content, but also has color fastness (Adhesion ability of fabric surface color)Better water resistance.
Of course, the production cost of good water-based elastic mucilage is high, but for high-end customers, we still must provide a better product quality.
As a manufacturer with many years of production of environmentally friendly bags, we have always been in the attitude of the person in charge of the customer, no matter what kind of customer requirements, we will provide the best service to our customers with our professional quality.
