There are many kinds of Non Woven Bag technology.
Non Woven Bags are usually used in screen printing process, which is often referred to as "screen printing". This is also a printing
process commonly used by many manufacturers. Generally, the color control of the process is not controlled, so many new
non-woven printing methods have been created, which introduce the mainstream of the market:
However, with the continuous improvement of the quality and environmental protection requirements of the products, many new
non-woven printing methods have emerged, which introduce the mainstream of the market:
A, the watermark
Because of its use of water-based elastic paste as a printing medium, it is more common in textile printing, also known as printing.
When printing, mix the color slurry with water - based elastic glue. Do not use chemical solvents when printing, can rinse directly
with water. It is characterized by good shading, strong covering, fastness, washable, and almost no smell.
2. Gravure printing
The finished products used in this method are usually called multifilm Non Woven Bags. This process is divided into two steps: first,
the traditional gravure printing process will be used to print the image on the film, and then the coating process will be used to
compound the film with the pattern on the nonwoven fabric. This process is used in the Non Woven Ultrasonic Bag of large area
color pattern printing. It is characterized by exquisite printing, the whole process of machine production, short production cycle.
In addition, the product has excellent waterproof performance, and the durability of the finished product is better than the
Non Woven Ultrasonic Bag produced by other processes. The film has two kinds of light and sublight, the sublight has frosted
effect! The disadvantage is that there is a conflict with the concept of environmental protection, because the film is difficult to
degrade.
Heat transfer
Heat transfer printing belongs to special printing! This method requires intermediate medium, which is to print the picture first to
the heat transfer film or the heat transfer paper, and then transfer the pattern to the nonwoven fabric by adding temperature on
the transfer equipment. The commonly used medium in textile printing is heat transfer film. Its advantages are: the printing is
exquisite, has rich level edition, can compare the photograph. Suitable for small area color image printing. The disadvantage is
that the price is high, the printing cost is high, and the effect is not natural.
Traditional plastic bag shopping bags have been used in the past, plastic bag factory to save cost so the materials are thin and
fragile. But to make him stronger, he would have to spend more. Nonwoven ultrasonic bag has solved all problems, non-woven
shopping bags, toughness and not easy to wear. There are a lot of laminated non-woven shopping bags, which are more durable,
more waterproof, feel good, and have a nice appearance. Although a single cost is a little bit more than a plastic bag, its service life
is a non-woven shopping bag that can reach hundreds or even thousands of plastic bags.
