Have you ever had this experience?   Walk into a stylish cafe and the waiter hands you a kraft paper bag emblazoned with the shop's logo. At Christmas, you receive a gift wrapped in plain kraft paper, tied with twine and pine cones. Or, while sorting through old belongings, you come across a yellowed kraft-covered notebook, bearing the marks of time.   Kraft paper always seems to play an unassuming yet indispensable role in some corner of our lives. It's not as glossy and colorful as coated paper, nor as colorful as fine art paper. It's simply what it is, with an innate sense of simplicity, warmth, and reassurance.   But you might not know that this seemingly simple paper is actually quite a tough guy.   The secret is in the name: the power of "Kraft." "Kraft paper" sounds impressive, but its strength doesn't come from cowhide. Its English name is Kraft Paper, and "Kraft" means "strength" in German.   The name originates from 1879, when Swedish chemist Carl F. Dahl invented a new pulping method—the sulfate process. He discovered that the pulp produced by this method had exceptionally long and strong fibers.

Thus, the resounding name "Kraft Paper" was born.   So, the next time you lift a heavy kraft paper bag and feel it securely hold its contents, remember that this sense of security is in its DNA.   From packaging to art, it's everywhere.

Its natural color and rough texture create a sense of down-to-earth beauty. Many brands are using it for business cards, tote bags, and menus, which is not only environmentally friendly but also conveys a genuine, unpretentious brand image.   In the handmade community, it's a favorite among creators.
