As sustainability requirements and global plastic reduction policies continue to expand, paper packaging is becoming an increasingly important solution in the flexible packaging industry. Different paper substrates present challenges such as high ink absorption, moisture sensitivity, surface roughness and registration instability during high-speed flexographic printing production.
Changhong flexo printing machine provides tailored paper printing solutions for various packaging applications, helping manufacturers achieve stable printing quality, efficient production performance for paper packaging printing applications and reliable material adaptability across different paper structures and converting processes.
Paper Flexo Printing Solutions
Changhong flexo printing solutions work with paper substrates ranging from 12 to 400 gsm, and keep stable performance in all kinds of packaging application scenarios.
Kraft Paper
Great for eco-friendly packaging bags, food packs and industrial packaging. It's tough enough and has really solid load-bearing ability.
White Cardboard
Best for high-end packaging, labels and paper box printing. Its smooth surface does a great job showing fine patterns and bright colors.
Coated Paper
It has great surface gloss and shows ink really well, so it's widely used for food and daily chemical packaging.
PE Coated Paper
Good for paper cups, food packs and moisture-proof packaging. It's easy to print on and also has reliable waterproof performance.
Food Grade Paper
Made just for bread bags, fast food containers and food paper packaging, and it fully meets all food-grade production standards.
Recycled Paper
A go-to choice for eco-friendly, sustainable packaging. When printing with flexo, it needs steady tension control and smooth web handling.
Main Challenges in Paper Printing
- Different types of paper absorb ink differently, which often makes the colors look inconsistent.
- When printing at high speeds, paper tends to stretch and the web can go off track.
- The fiber structure of paper affects how accurate the printing registration can be.
- Lightweight paper is more prone to wrinkling or tearing during the printing process.
- Thick paper needs more precise tension control when unwinding and rewinding.
- The drying speed of water-based ink is a bottleneck for overall production efficiency.
