The printing process of environmental
protection shopping bags generally adopts screen printing, which is often
referred to as "silk screen printing" in China printing. But in the actual production process, often some
customers will say: why some bags printing effect is good, some printing effect
is poor? Of course, this has a great relationship with the proficiency of
printing workers and printing technology, on the other hand, it also has a
great relationship with the choice of printing ink. Generally, we can choose
two kinds of printing ink, one is water-based elastic glue, the other is ink.
For example, the general non-woven fabric bag printing is the use of water-based
elastic glue. The biggest characteristic of this kind of water-based elastic
glue is that the effect after printing has obvious concave and convex feeling,
and the coverage rate is good, water-resistant, and basically no odor. The ink
is generally used in screen printing of ordinary materials, such as the surface
of metal box, etc., the biggest feature of this printing process is that High
printing accuracy. Why do we use water-based elastic glue for printing on
environmental protection bags? This is mainly due to the following
reasons:
1. Water based elastic glue is a kind of
relatively environmentally friendly ink, and basically has no peculiar smell.
Therefore, since we are making environmental protection bags, of course, we
should choose environmental friendly ink in China printing.
2. Different from the surface of ordinary
objects, the mesh on the surface of cloth is relatively large. If the coverage
rate is not good, that is to say, after printing, a lot of the background color
of the cloth itself will be exposed, so the printing effect will be very ugly.
Therefore, because of the surface properties of the cloth itself, we use
water-based elastic glue.
There is another case that some customers'
orders need to be exported to some European and American countries. Therefore,
relatively speaking, there are higher requirements for the environmental
protection performance of ink. At this time, we need to be more cautious, so as
not to pass the environmental protection test when importing customs in other
countries. In this case, we generally recommend that customers choose the
water-based elastic glue with high environmental protection performance. This
kind of high environmental protection performance water-based elastic mortar
not only has low content of heavy metals, but also has better color fastness
(adhesion ability of fabric surface color) and washing resistance. Of course,
the production cost of good water-borne elastic mortar is high, but for
high-end customers, we still have to provide a better product quality. As a
manufacturer of environmental protection bags for many years, we have always
been in line with the attitude of the person in charge of customers. No matter
what kind of customer requirements, we will provide the best service for
customers with our professional quality in China
printing.
