What should be noted when printing non-woven eco-friendly bags?

The printing process for environmentally friendly bags often uses screen printing, also known as “screen printing”.

But in the manufacturing process of practice, customers often ask why some non-woven environmentally friendly bags have good printing effects, while others have poor printing effects? Of course, this is closely related to the proficiency of printing workers and printing techniques, as well as the selection of printing ink.

Generally, there are two types of printing inks available for us to choose from: water-based elastic adhesive and ink. For example, the general printing on non-woven bags in Shandong uses water-based elastic adhesive. The main feature of this water-based elastic adhesive is that it has a significant concave convex feeling after printing, good coverage, water washing resistance, and no odor at all. Ink is generally used for screen printing of general objects, such as the appearance of metal boxes, etc. The main feature of this printing process is high printing accuracy. Why do we use water-based elastic adhesive for the printing on our environmentally friendly bags?

This is mainly influenced by the following factors

1. Unlike the surface of ordinary objects, the mesh on the fabric surface is relatively large. Choosing regular ink printing, if its coverage is not good, that is to say, after printing, many of the fabric’s own background colors are exposed, the printing effect will be very unsightly. Therefore, because of the surface properties of the fabric itself, we use water-based elastic adhesive.

2. Water based elastic adhesive is a relatively environmentally friendly ink, and it has basically no odor. Therefore, since we are making Shandong non-woven environmentally friendly bags, of course, we should choose environmentally friendly ink.

Standards for UK and US clients

Another situation is that some customers require their orders to be exported to some European and American countries, so relatively speaking, there is a higher demand for the environmental protection function of ink. At this time, we need to be more cautious to avoid being unable to go through environmental testing during import customs declaration in other countries. In this situation, we generally advocate that customers choose water-based elastic adhesives with high environmental protection functions. These water-based elastic adhesives with high environmental protection functions not only have low heavy metal content, but also have better color fastness (the ability to adhere to the surface color of the fabric) and water washing resistance.

Of course, good water-based elastic adhesive has a high manufacturing cost, but for end customers, we still need to provide a better product quality. As a manufacturer of environmentally friendly bags with many years of experience, regardless of the type of customer’s request, we provide excellent service to our customers with our professional essence.
