1. Single-Coated Paper: Also known as single-sided coated paper, this material features one smooth side and one matte side, with only the smooth side being suitable for printing. This material allows for diverse color printing capabilities, offering unlimited color options. Common post-printing finishing processes include lamination, UV coating, hot stamping, and embossing.
2. Double-Coated Paper: Also known as double-sided coated paper, this material is renowned for its smooth finish on both sides. Possessing a premium texture, this paper is frequently utilized for high-quality products, such as those produced by Junye Packaging Printing.
3. Corrugated Paper: Corrugated paper is formed by laminating smooth kraft paper with a wavy paper layer (the paper core); it is a vital material within the paper packaging industry. Compared to standard paper, corrugated paper offers greater rigidity and superior load-bearing capacity. While it supports printing in various colors, the print quality is generally not as sharp as that achieved on single-coated paper. Common post-printing surface treatments include lamination, UV coating, hot stamping, and embossing.
4. Specialty Paper: Specialty paper refers to papers designed for specific applications and produced in smaller quantities. This category encompasses a wide variety of types, including embossed paper, patterned paper, "Ningcai" pearlescent paper, "Xingcai" metallic paper, and gold paper. These papers undergo specialized treatments to elevate the tactile quality and premium aesthetic of the packaging. Embossed and textured papers typically do not accept standard printing and are limited to surface hot stamping; however, varieties such as "Xingcai" and gold paper are compatible with four-color printing.
5. Cardboard: Cardboard is a staple material for constructing the structural framework of gift boxes; its surface is typically laminated with a layer of single-coated paper or specialty paper. Common cardboard colors include black, white, gray, and yellow, and it is available in various thickness grades to meet diverse load-bearing requirements. If the cardboard is laminated with single-coated paper, the finishing processes mirror those used for standard single-coated paper boxes; if laminated with specialty paper, finishing is-in most cases-limited to hot stamping, although some specific materials may accommodate simple printing, albeit potentially with suboptimal results.
