Many customers who are making bags for the first time do not know much about non-woven bags. They often ask what printing methods are generally used for non-woven bags. Zhoukou Hongyuan Packaging Technology Co., Ltd. will explain non-woven bags in detail here. What kind of printing method will cloth bags use? We have been working on non-woven bags for 10 years. We have been studying the printing process of non-woven bags and hope to help you.

　　Non-woven bag printing methods commonly used include screen printing, rubber embossing, thermal transfer, gravure color printing, and glue color printing.

　　 Let's analyze the advantages and disadvantages of various printing methods one by one

  screen printing

　　Introduction: Screen printing on the fabric with a screen printer, using environmentally friendly ink and screen.

　　 Commonly known as: silk screen, watermark, environmental printing.

　　Advantages: affordable, fast, low cost, bright colors, and accepted by the public, wide range of applications.

　　 Disadvantages: Unable to print images with large gradients, such as portraits, landscapes, houses, etc.

　　 Rubber plate embossing

　　Introduction: A six-color cylinder printing machine is used to print on the fabric, and the engraved rubber plate is used to paste on the rubber roller cylinder, using environmentally friendly ink.

　　 Commonly known as: offset printing (different from paper offset printing), embossing, flexo printing.

　　Advantages: low price, fast speed, a little bit of brightness in the color, widely used in society.

　　 Disadvantages: The color is relatively light, and it is only suitable for lightly pigmented fabrics, such as white, beige and other lightly pigmented fabrics.

　　 heat transfer

　　Introduction: Using an offset printing machine and a hot stamping machine, first use the offset printing machine to print on the heat transfer paper, and then use the hot stamping machine to flat iron or boil it on the fabric. Commonly known as: heat transfer, heat transfer, sublimation printing.

　　Advantages: It can print high-precision pictures such as human heads, landscape paintings, etc., with high concentration, which makes the printing of bags look very bright.

　　 Disadvantages: the printing area cannot be too large, the price is higher, and the speed is slower.

　　 gravure color printing

Introduction: Using a seven-color gravure printing machine, the pattern is carved on the roll gravure (the material is iron), then the plate is placed on the printing machine, printed on the OPP film, and then covered on the non-woven fabric by the laminating machine superior.

　　 Commonly known as: color printing, gravure printing.

　　 Advantages: The size of the pattern is arbitrary, no need to reduce the pattern deliberately, it can print high-precision pictures such as human heads, landscape paintings, etc., with high concentration, so that the entire bag presents a beautiful picture. When the number of bags is large, the price advantage is obvious and the speed is fast.

　　 Disadvantages: The version fee is expensive, and the cost allocation for a small number of bags is relatively high.

　　This printing method is still a topic worthy of controversy for environmental protection.

　　Leaching glue color printing

　　 Introduction: The most recent printing method. A layer of glue is poured on the inner layer of the non-woven fabric to block the leakage of the ink, thereby performing color printing.

　　Advantages: It can be directly color printed on the non-woven bag without filming or transfer paper, and the cost is relatively reasonable. Suitable for the printing of 50-10 million bags.

　　 Disadvantages: The color accuracy is slightly lower than that of the film, and the color of the fabric should be slightly plain, which is not suitable for the full-page background color.

　　 Such several printing methods have covered all the current printing methods in the non-woven bag industry, I hope to help you.
