Kraft paper has the advantages of hard and strong texture, good toughness, abrasion resistance, and not easy to tear and break. Kraft paper can be recycled and reused many times, and the price is not high, the printing cost is low, no film is required, and the cost is saved. Because of these good properties, kraft paper packaging is very popular. SIUMAI packaging uses UV ink to print kraft paper, which can be professionally printed with white ink. The printing effect is clear and efficient. Because the soap packaging needs to be moisture-proof and oil-proof, kraft paper is very used for packaging soap. Kraft paper packaging is 100% recycled and reused, which is an important point that kraft paper is superior to other packaging materials. Even for it, the kraft paper will quickly be degraded in the soil "turned into spring mud to protect the flowers." Unlike plastic packaging, which is difficult and easy to degrade, it causes "white pollution" and has a destructive effect on the soil and the environment.
