Plastic woven bag printing process

With the development of the times, some new technological inventions emerge in an endless stream. Do you know the popular plastic woven bags? Plastic woven bags can be said to be of various types now, and printing technology can be said to be more and more extensive. Then, YG plastic woven bag making machine manufacturer will talk to you about the printing process of plastic woven bags!



The printing process of plastic woven bags includes screen printing, mechanical printing, heat transfer printing, film-coated color printing, and other processes, each with its own characteristics and advantages and disadvantages. Let's talk screen printing. It is printed with water-based inks. It has very good environmental protection. Environmental protection is very important to today's society. The earth is the home of all of us, and we have an obligation to protect the earth's environment. The advantage of screen printing is that the filling rate is uniform. In terms of appearance, it must be more beautiful. Girls might like it. The disadvantage of screen printing is that the construction period is longer and the cost is higher, which may be affected by sales. In production, it is more suitable for small-batch production.


Another printing process is machine printing. The PP bag printing machine printing is water-based ink, it is environmentally friendly. Ink is plain. In terms of filling, it can be thinner, not as full and beautiful as screen printing. Its advantage is that the production cycle is short, the cost is low, and it is suitable for mass production.




There are thermal transfer plastic woven bags. The printing pattern is beautiful and the layers are distinct. If you are a visual creature, this is a good choice. It is usually used for small-area color image printing, and good-looking things are generally expensive, and this is no exception, and the production cycle is longer and more expensive. How, varies from person to person, and there is nothing wrong with choosing according to your preferences. There are more and more plastic woven bags, and more and more people can choose.


The printing process of color printing woven bags is mainly reflected in the selection of printing ink and printing method. Color printing woven bags are printed with special plastic inks, which have strong adhesion on the woven bags and are not easy to fall off.


1. If the printing quantity is small, you can use flat screen printing, which is characterized by "flexible and convenient plate making, can be printed by woven bag printing machine, or printed by hand". However, the service life of screen printing is relatively short. Generally, there will be a missing version after 10,000 to 20,000 times of use, and the version needs to be revised; the maximum limit of screen printing may not exceed 30,000 times.


2. If the printing quantity is large, you can use roller metal screen printing or roller offset printing, which are large-scale printing machines with fast printing speed and long service life of the plate, but the printing process is relatively complicated, and one plate can be printed about 100,000 times above. Flat screen printing and roller metal screen printing are not suitable for multi-color printing, generally only for single-color or two-color printing, otherwise the register process is complicated and the efficiency is low; while roller offset printing can be multi-color printing. Color printing woven bag printing needs to be dried or dried after the finished product is finished because of the ink, otherwise the printed content is easy to stick, which is very important.


The woven bag printing machine integrates printing, counting and bag collection. It is a device for printing text and patterns on woven bags.




Features:



1. The counter can prefabricate the alarm;

2. From 1500-3500 per hour, stepless speed change;

3. Imported PVC conveyor belt, automatic positioning;

4. Automatic tracking and separation of printing sticks;

5. The oil bucket can be exchanged at will, and the ink transfer stick and printing plate can be separated;

6. The ink is transferred by the net stick, which increases the printing smoothness and saves ink;

7. Post-conveying extension, drying function.

  Plastic toys are a common product in our daily life, so do you know how it is made?   YG injection molding machine manufacturers   tell you that most of them are made by injection molding. Other plastic products, plastic chairs, plastic basins, plastic baskets, plastic toys, car upholstery, earphones, etc. are also made by injection molding. Why are children's toys made of plastic? Plastic is a material with high polymer as the main component. Plastic softens when heated, hardens when cold, easy to form, easy to color, and wear-resistant. And the plastic toy is very light, and the baby will not have any pressure in the hand. Toys made of plastic are easier to disinfect and clean, and will not bring any hidden dangers to the baby. Another important reason is that plastics are easy to mold. Molten plastic is molded into various shapes of toys through various shapes of molds. This is why plastic toys are so colorful. So what are the materials used to make plastic toys? Pla...

How are plastic bags produced?

In contemporary life, plastic bags have become an integral part of our daily life. They are widely used in supermarkets, shops and other retail establishments because they are cheap, convenient, durable and easy to carry. However, these plastic bags have a huge negative impact on the environment during production, use and disposal. In order to reduce the negative impact on the environment, many countries have begun to restrict the use of plastic bags, but the demand for plastic bags is still high, so efficient production processes are required.   Plastic bag raw material   The raw material of plastic is petroleum, which is refined to obtain polyethylene, polypropylene, polystyrene, etc., and then plastics are produced from these refined substances. Polyethylene, polypropylene, and other by-products that can be used to make plastics are all polymer compounds, but plastics are processed into plastic products after they are catalyzed.   How are plastic bags made?

  What is the plastic film? Technically speaking, plastic film is any plastic with a thickness of less than 10mm, and it is usually made of polyethylene (PE) resin, such as  garbage bag , common zipper bags, food bags, bubble wrap, agricultural plastic films,  PP woven bag , etc. At present, the global demand for plastic film continues to rise. Plastic products are difficult to decompose, and if they are not recycled, the harm to the environment is huge. Therefore, the recycling of plastic films is of great significance. So how to recycle plastic film? Significance of waste plastic film recycling: In recent years, with the large-scale promotion of plastic film mulching, especially the full-film double-furrow sowing technology, the use of agricultural film has increased year by year, and the problem of “white pollution” has become increasingly prominent. The main component of waste agricultural plastic film is polyvinyl chloride or polyethylene, which is difficult to degra...
