What are the printing methods for non woven bags? Ask for guidance!

Silk screen printing: After the design draft is finalized, three printing processes must be made: film, plate making and drying. The area of screen printing, the number of colors, the number of printing surfaces, the complexity of color registration, the quality of the printing paste, the weather is sunny or rainy and many other factors will have an impact on the cost.

Process advantages: the process application is the most common, the cost is relatively low, and the minimum quantitative limit is small; Generally, 1000 pieces are sufficient.

Scope of application: no gradient color or non-color printing of the printed content; Registering can't be overly complicated.

Laminate printing: Any pattern can be printed, even the most complex printing can be realized. The cost of printing plate making is high, and the plate making cost is related to the area and color quantity of plate making; The printing cost is only proportional to the size of the printing area, and the peritoneal process is suitable when the quantity is large and the printing area is large.

Process advantages: any pattern can be printed, with a minimum minimum of 5000 pieces.

Scope of application: No restrictions.

Machine printing: The thickness of this printing ink or paste is thinner, and the cost is slightly lower than that of screen printing, and many printing contents are inconvenient to use this process.

Process advantages: the lowest printing cost and faster production speed.

Scope of application: no gradient or non-color printing of the printed content, and the dark printing effect is better when printing on light-colored fabrics.

Hot stamping printing: This printing can print any pattern, there is a plate-making fee and printing start-up fee, and the printing cost is proportional to the size of the printing area.

Process advantages: Any pattern can be printed, and gradient colors or color patterns with a small area are the most suitable for this process.

Scope of application: Any pattern can be printed, and the minimum starting weight is relatively high, generally more than 5000 pieces.

It is usually screen printing, with gradient color or complex color transfer printing or laminated color printing. Here the screen printing ** is lower. Thermal transfer takes a long time and costs a little more. The effect of laminated bags is good, but it is not environmentally friendly.

There are 4 main types of printing of non-woven bags:

1.Hand printing is a type of on-the-spot printing. Advantages: The printing effect is excellent, and the thick and pure field is heavy. Disadvantages: slow speed, tall adult.

2.There are two kinds of flatbed machine printing and web machine printing. Advantages: fast speed and low cost. Disadvantages: The printing effect is generally light, and the printing effect is slightly better.

3.Color printing, engraving by electric engraving, gravure printing. It can print more than a dozen colors. It can also be laminated by lamination.

Advantages: excellent printing effect and fast speed. Disadvantages: The production is annoying, the cost is high, and the waste is large.

4.Thermal transfer, disadvantages: slow speed and high cost, advantages: excellent effect.

There are currently two kinds of non-woven printing, one is machine printing, high efficiency, the disadvantage is that the ink coverage rate is not good, which affects the printing effect, and the other is the silk screen treadmill printing, the advantages are just complementary to the machine printing, if you have any questions, you can contact me to leave a message, you can also find me if you need a master.

Basic Methods of Printing:

Non-woven shopping bag printing generally uses screen printing, but because screen printing has the shortcomings of expensive equipment, complex plate-making color matching and cumbersome production process, especially screen printing needs mass production to reduce costs.

In contrast, with the continuous improvement of inkjet technology, sublimation inkjet printing technology has begun to replace screen printing in non-woven printing.

Non-woven shopping bag.

Dye sublimation inkjet technology is to use the characteristics of CP2199SDFJSDKFKJ inkjet printer without plate direct output, using sublimation inkjet ink to spray exquisite patterns directly onto sublimation paper, and then transfer to non-woven fabrics through the heat transfer machine.

Non-woven fabrics treated with special fabrics can also be sprayed directly with a printer without sublimation paper. Sublimation inkjet printing non-woven shopping bags have the characteristics of cheap equipment, easy operation, no plate-making, simple process, etc., especially in printing precision images, screen printing is almost impossible to accurately reproduce the fine history of the beautiful picture, sublimation inkjet printing can reach the professional image level of printing.

1. Heat transfer printing in the production of non-woven bag printing: Heat transfer in the production of non-woven bag printing is the most common production method, this printing production process is to first print the first to the heat transfer film or heat transfer paper, and then transfer the pattern to the non-woven bag by heating the transfer equipment. The advantages are:

The printing is exquisite, there are rich layered plates, comparable to **.

2. Watermark in the production of non-woven bag printing: Now the application of watermark in the production of non-woven bags is greatly improved, and the watermark production process of non-woven bags is to mix the color paste and water-based elastic glue. The plate is processed without chemical solvents and can be rinsed directly with water.

It is characterized by good tinting strength, strong coverage and fastness, washability, and basically no odor.

3. Gravure printing in the production of non-woven bag printing: The finished product processed by this method is usually called a laminated non-woven bag. This process is divided into two steps, that is, the traditional gravure printing process is used to print ** on the film, and then the film with the pattern is laminated on the non-woven fabric by the laminating process.

Laminated non-woven bag process requirements:

1.When laminating the membrane, pay attention to whether there is blistering and the lamination is not firm.

2.Cutting: Each set of plates has a white line, and the error should not exceed 1-5 mm when cutting.

3.The small area of wrinkles of each piece cannot be crossed by 2 places.

4.There are 2 white boxes at both ends of each plate when making plates, which is where the carrying tape is installed.

Lifting belt: When ironing the belt and sewing the belt, the error is 1-2 mm, there is no white box when making ordinary non-woven bags, but a standard must be found, the belt is sticky and ironing, the length of the belt is 45 cm, and the cloth is not less than 65 grams.

5.Running head: the error of 3 cm of the folding edge shall not exceed 1-2 mm, the upper line is 2 mm from the fold, no jumper is allowed, the needle must be returned once at the beginning of the sewing and the upper lifting belt, and the needle distance of 1 cm is the needle when running the head.

6.Wrapping: When wrapping, the needle distance on the bib is 1 cm and 3 needles, the line distance between the bib is 1-2 mm when the envelope, the gram weight of the bib cloth is 65-70 grams, there can be no wrinkling, the color of the bib is as consistent as possible with the color of the front of the bag, the line should be consistent with the color of the bib, there must be no opening, check it again after closing the bag, and the thread must be cut off.

7.Stacking: Stacking this link is very important, for the standard inspector, check whether there is a thread, whether there is a break in the edging, whether the belt is correct, all the above standards must be checked, whether the stacking can be aligned up and down, and the error does not exceed 5 mm.

Summary: From the beginning to the end, each link is very important, the next process is the inspector of the previous process, the next process checks that there is something wrong with the previous process, reminds the previous process to pay attention, and to rework, to avoid a series of faults caused by losses.

Depending on your needs, the process is different.

The processing of non-woven bags is relatively simple, there will be differences in workmanship, printing, and materials, and there will be differences, but it is not easy to say which must be good, the key is to see the degree of customer requirements for quality, and whether the business is responsible for quality. The material of non-woven fabrics is mainly to consider whether the material is new, the ordinary material doped with recycled materials (some are doped more, some are less, and some add talcum powder, calcium powder, etc. to increase the gram weight), and how thick the fabric is (the standard is the gram weight, that is, how many grams per square meter), it is best to look at the sample first and then place an order.
