As a common packaging product in daily life, the durability and clarity of the printed pattern on PE vest bag are directly related to the overall image and publicity effect of the product. In the printing process, a series of professional technologies and quality control measures can be used to significantly improve the durability and clarity of the pattern on PE vest bag.First of all, the choice of ink is crucial. Screen printing inks designed for plastic materials should be used. Such inks not only have good adhesion and flexibility, but also ensure that the color of the printed pattern is bright and durable. Avoid using inferior inks, because inferior inks tend to fade gradually during use, affecting the overall appearance.Secondly, the surface treatment before printing should not be ignored. The surface tension of PE material is low, and direct printing may cause the ink to not adhere firmly. Therefore, before printing, the PE vest bag needs to be corona treated or coated to increase its surface tension and ensure that the ink can adhere firmly. This step is crucial to improving the durability of the printed pattern.In the printing process, choosing the right printing technology and operation method is also critical. The use of advanced screen printing technology, combined with precise plate making and debugging, can ensure the clarity of the pattern. At the same time, the viscosity of the ink and the angle of the scraper should be strictly controlled during the printing process to avoid drawing or smudges during the printing process. In addition, maintaining a stable printing speed is also an important factor in ensuring that the pattern is uniform and clear.After printing, the drying and curing steps are equally important. Using an infrared dryer or a hot air dryer can quickly cure the ink and enhance the adhesion and wear resistance of the pattern. During the drying process, the temperature and time should be moderate to avoid excessive drying that may cause material deformation or ink cracking.Finally, quality control is the key to ensuring the durability and clarity of the printed pattern. During the printing process, regular sampling and testing of the printing effect should be carried out to ensure that each batch of products meets the quality standards. At the same time, regular maintenance and maintenance of the printing equipment to ensure that the equipment operates normally is also an important measure to ensure printing quality.In summary, by selecting suitable inks, conducting adequate surface treatment, adopting advanced printing technology and operating methods, strictly controlling the drying and curing process, and strengthening quality control, the durability and clarity of the printed pattern on the pe vest bag can be significantly improved. These measures not only help to enhance the overall image of the product, but also bring better publicity effects to the company.
