The Kraft Paper Hamburger Box is available in both white and yellow kraft paper. White kraft paper is a commonly used paper for printing. Food-grade white kraft paper is mainly made of sulfate conifer bleached pulp. Its whiteness is not very high and even has a faint yellow color. If a white kraft paper is very white and ultra-white, it may be a fluorescent whitening agent added to the raw material of the product. The fluorescent agent is easy to accumulate in the human body. Long-term intake will seriously damage the human immune system and even lead to cancerous cells. It is not allowed to be used as Kraft Paper Hamburger Box.
Have you ever wondered why kraft paper is called "kraft" paper, because the color resembles cowhide? Although kraft paper looks like cowhide in appearance, the yellow-brown paper gives people a healthy and simple feeling to some extent. Kraft paper has already evolved, or it is no longer satisfied with simple packaging. As a renewable and environmentally friendly resource, kraft paper will go to a deeper and wider field. In the early days, people did use cowhide to wrap things, and later they used kraft paper. In addition to the name and color, the more important thing is that the kraft paper needs to be as wear-resistant as cowhide, so the more significant advantages of kraft paper are its strength, flexibility and strength, and high bursting resistance. Can withstand greater tension and pressure without breaking. Since its development, the Kraft Paper Hamburger Box made of kraft paper seems to have made new progress in "packaging".
There are two common types of Hamburger Boxes. One is direct printing. Since kraft paper has a good waterproof and moisture-proof effect, the used packing boxes can be put away for future use, saving resources. There is also a packaging box that can be pasted with self-adhesive, and after a product is used up, it can be replaced with a label to continue to store other items for recycling. The economic input of recycling and remaking is avoided, and the cost is also reduced.
