How are alien packaging bags printed and made?

The printing process of irregular packaging bags needs to be designed and adjusted according to specific situations. The following are the general steps:
1. Creating a design draft: Firstly, it is necessary to create an accurate design draft, including the shape, size, pattern, text, and other elements of the packaging bag. Design drafts can be drawn using CAD software or created using 3D modeling software.
2. CTP plate making: The design draft is made into a CTP (Computer to Plate) plate, which can be digitized and converted into a printable layout.
3. Machine printing: Install the CTP plate onto the printing machine for machine printing. Before printing, it is necessary to choose a suitable printing machine and paper, while considering factors such as printing quality and efficiency.
4. Surface treatment: After printing, the printed paper is subjected to surface treatment such as glazing, sanding, laminating, etc. These treatments can increase the glossiness, waterproofness, wear resistance, etc. of the paper, and improve the quality and durability of the packaging bag.
5. Die cutting: Die cutting is a key step in making irregular packaging boxes, where the printed paper is cut into the desired shape using a die cutting machine. When die-cutting, it is necessary to consider the shape and design requirements of the packaging box to ensure that the cut paper can be accurately spliced into the desired box shape.
6. Adhesive: Glue the cut paper together to form the shape of an irregular packaging bag. Proper adhesive is required during bonding to ensure the box is firm, not deformed, and to maintain its appearance and stability.
7. Inspection: During the printing and production process, it is necessary to conduct quality inspection on the packaging bags to ensure that they meet the design requirements and standards. Inspection includes checking the shape, size, printing quality, surface treatment, and other aspects. In general, the printing of irregular packaging bags needs to consider multiple factors, such as paper material, printing technology, production process, etc. At the same time, it is necessary to design and adjust according to the needs and aesthetic requirements of customers to meet the demands of different markets.
