1. Later design and what material to choose
The design and manufacture of luxury paper boxes is the key link of the entire paper bag consumption process. Luxury paper box selection of materials, decorative techniques, and performance are inseparable from the use and effectiveness of paper bags. Kraft paper is good toughness, high strength, rougher appearance. Cardboard stiffness is good but poor toughness, used as a paper bag general need for exterior lamination. Copperplate paper has a certain toughness, rich printing color, but the stiffness is worse than cardboard. Emphasize the durability of the choice of kraft paper, luxury packing boxes on the color and stiffness are delicate when the majority of cardboard, and the need for rich and colorful pattern effect, people tend to prefer coated paper. To improve the taste and level of portable paper bags, designers in the post-printing exterior decorative processes on the brain. Of course, no matter what kind of finishing process is used, designers should think about the economic application of paper materials, process design sensibility. For the sake of consumption and quality control, it is indispensable to create a set of complete and clear work engineering drawings when designing, and in a few cases, the goods also need to be confirmed by proofing.
