Compared to the plastic bags we commonly use, paper bags are more environmentally friendly. Therefore, people nowadays have generally started using paper bags. What are the materials of paper bags?
1. Advantages of kraft paper: It has high toughness and solidity, is not easy to tear, and is generally suitable for printing monochrome or two-color paper bags with limited color options.
2. The advantages of white cardboard are: solid, durable, and very smooth. The printed colors are rich and full. Paper bags commonly use 210-300 grams of white cardboard, with 230 grams of white cardboard being the most commonly used.
3. The advantages of black cardboard are: solid and durable, with a black color. Because black cardboard itself is black, its biggest disadvantage is that it cannot print colors, but it can be used for processes such as hot stamping and silver stamping.
4. The material characteristics of copperplate paper are good whiteness and glossiness, which can make the image and picture reflect a three-dimensional sense during printing, but its solidity is not as good as white cardboard. The thickness of copperplate paper commonly used in paper bags ranges from 128 to 300 grams. The commonly used sizes are: 120-300 grams
In summary, the materials of paper bags mainly include kraft paper, white cardboard, black cardboard, and copperplate paper.
