Environmental protection problems of non-woven environmental protection bags in the printing process

Today is an environmentally friendly era. Now citizens who enter the supermarket do not ask for plastic bags, and gradually develop a good habit of everyone carrying their own non-woven handbags. In fact, everyone has already developed such a good habit abroad. It is more in line with the low-carbon environmental protection that our country now advocates. In fact, in many cases, the rationality of the handbag is also very important. For example, whether this handbag is humanized, and whether it can reduce the burden on others when loading other items is critical. The main material of non-woven eco-friendly bags is non-woven fabric. Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form new fiber products with soft, air-permeable and planar structure through various web forming methods and consolidation technologies. Advantages: non-woven bags are inexpensive and good-quality, environmentally friendly and practical, widely used, and have prominent advertising positions. It is suitable for all kinds of business activities and exhibitions and fairs, and is an ideal advertising promotion gift for enterprises and institutions. The raw material of the non-woven fabric is polypropylene, while the raw material of the plastic bag is polyethylene. Although the two substances have similar names, they are quite different in chemical structure. The chemical molecular structure of polyethylene is very stable and extremely difficult to decompose. Therefore, it takes 300 years for the production process of non-woven bags (2 sheets) to complete the decomposition of plastic bags; while the chemical structure of polypropylene is not strong, and the molecular chain is very It can be broken easily, which can be effectively degraded, and enter the next environmental cycle in a non-toxic form. A non-woven bag can be completely decomposed in 90 days. Now the company has developed and innovative new color eco-friendly bags. The color-printed eco-friendly bags are made of high-thickness eco-friendly non-woven fabrics of more than 120 grams, and they are printed once. Fast and environmentally friendly printing technology coupled with high-quality fabric products are quickly accepted by customers. The price is only the same for the three colors of screen printing, and it is 30% more than the bottom of the thermal transfer environmental protection bag. Such low-cost and high-quality products have now been obtained by major clothing, food, home textiles and municipal units with higher environmental protection requirements. Tote bag printing can usually be based on the specifications of different tote bags, or to print different words or patterns on the surface of the tote bag, which can effectively promote the corresponding brand. Due to the different materials used, there is usually a big difference in the publicity function. If we use paper handbags, usually its usage rate will be relatively small. What's more interesting is that most of the traditional printing companies that first set foot in digital printing were those companies that first introduced imagesetters and then CTP. They are either large-scale printing companies with corresponding customer needs and technical reserves, long-term strategic planning and practical application-oriented considerations for digital printing business, such as Li u0026 Fung Accor, etc.; or small and medium-sized printing companies with short, fast and flexible business These companies usually have been engaged in phototypesetting output and advertising design business, have a strong sense of crisis and service spirit, have the courage to pioneer and innovate, and have a keen business sense, such as Qiliang Hyde and Guangzhou Tianyi. From the perspective of digital printing applications, it will also be fully applied. Starting from the short-run supplementation of traditional printing, it gradually moved towards the production capacity of the medium version, while the cost performance of traditional printing gradually declined from the long-run to the short-run. Digital printing will be more widely used in the fields of large format packaging, large format posters and artwork reproduction, and commercial printing. Under the self-requirement of providing customers with one-stop printing services, printing enterprises will achieve a new and further integration of traditional and digital printing methods.
